LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 7.2 Pin description The pin description consists of two parts showing pin functions that are fixed to a certain package pin (see Table4) and showing pin functions that can be assigned to any pin on the package through the switch matrix (see Table5). The pin description table in Table4 shows the pin functions that are fixed to specific pins on each package. These fixed-pin functions are selectable between GPIO and the comparator inputs, SWD, RESET, and the XTAL pins. By default, the GPIO function is selected except on pins PIO0_2, PIO0_3, and PIO0_5. JTAG functions are available in boundary scan mode only. Table5 shows the the I2C, USART, SPI, and SCT pin functions, which can be assigned through the switch matrix to any pin that is not power or ground in place of the pin’s fixed functions. The following exceptions apply: For full I2C-bus compatibility, assign the I2C functions to the open-drain pins PIO0_11 and PIO0_10. Do not assign more than one output to any pin. However, more than one input can be assigned to a pin. Once any function is assigned to a pin, the pin’s GPIO functionality is disabled. Pin PIO0_4 triggers a wake-up from Deep power-down mode. If you need to wake up from Deep power-down mode via an external pin, do not assign any movable function to this pin. The JTAG functions TDO, TDI, TCK, TMS, and TRST are selected on pins PIO0_0 to PIO0_4 by hardware when the part is in boundary scan mode. Table 4.

TRST In ISP mode, this is the USART0 transmit pin U0_TXD. In boundary scan mode: TRST (Test Reset). This pin triggers a wake-up from Deep power-down mode. If you need to wake up from Deep power-down mode via an external pin, do not assign any movable function to this pin. This pin should be pulled HIGH externally before entering Deep power-down mode. A LOW-going pulse as short as 50 ns causes the chip to exit Deep power-down mode and wakes up the part. RESET/PIO0_5 4 3 3 1 [4] I/O I; PU RESET — External reset input: A LOW-going pulse as short as 50 ns on this pin resets the device, causing I/O ports and peripherals to take on their default states, and processor execution to begin at address 0. In deep power-down mode, this pin must be pulled HIGH externally. The RESET pin can be left unconnected or be used as a GPIO or for any movable function if an external RESET function is not needed and the Deep power-down mode is not used. I - PIO0_5 — General purpose digital input/output pin. PIO0_6/VDDCMP 18 15 15 - [9] I/O I; PU PIO0_6 — General purpose digital input/output pin.

SS [1] Pin state at reset for default function: I = Input; AI = Analog Input; O = Output; PU = internal pull-up enabled (pins pulled up to full V DD level); IA = inactive, no pull-up/down enabled. [2] 5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors and configurable hysteresis; includes high-current output driver. [3] True open-drain pin. I2C-bus pins compliant with the I2C-bus specification for I2C standard mode, I2C Fast-mode, and I2C Fast-mode Plus. Do not use this pad for high-speed applications such as SPI or USART. The pin requires an external pull-up to provide output functionality. When power is switched off, this pin is floating and does not disturb the I2C lines. Open-drain configuration applies to all functions on this pin. Remark: If this pin is not available on the package, prevent it from internally floating as follows: Set bits 10 and 11 in the GPIO DIR0 register to 1 to enable the output driver and write 1 to bits 10 and 11 in the GPIO CLR0 register to drive the outputs LOW internally. [4] See Figure11 for the reset pad configuration. RESET functionality is not available in Deep power-down mode. Use the WAKEUP pin to reset the chip and wake up from Deep power-down mode. An external pull-up resistor is required on this pin for the Deep power-down mode. [5] 5 V tolerant pin providing standard digital I/O functions with configurable modes, configurable hysteresis, and analog input. When configured as an analog input, the digital section of the pin is disabled, and the pin is not 5 V tolerant. [6] 5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors and configurable hysteresis. In Deep power-down mode, pulling this pin LOW wakes up the chip. The wake-up pin function can be disabled and the pin can be used for other purposes, if the WKT low power oscillator is enabled for waking up the part from Deep power-down mode. [7] 5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors and configurable hysteresis. [8] 5 V tolerant pin providing standard digital I/O functions with configurable modes, configurable hysteresis, and analog I/O for the system oscillator. When configured as an analog I/O, the digital section of the pin is disabled, and the pin is not 5 V tolerant. [9] The digital part of this pin is 3 V tolerant pin due to special analog functionality. Pin provides standard digital I/O functions with configurable modes, configurable hysteresis, and an analog input. When configured as an analog input, the digital section of the pin is disabled.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 8. Functional description 8.1 ARM Cortex-M0+ core The ARM Cortex-M0+ core runs at an operating frequency of up to 30 MHz using a two-stage pipeline. Integrated in the core are the NVIC and Serial Wire Debug with four breakpoints and two watchpoints. The ARM Cortex-M0+ core supports a single-cycle I/O enabled port for fast GPIO access. The core includes a single-cycle multiplier and a system tick timer. 8.2 On-chip flash program memory The LPC81xM contain up to 16 kB of on-chip flash program memory. The flash memory supports a 64 Byte page size with page write and erase. 8.3 On-chip SRAM The LPC81xM contain a total of up to 4 kB on-chip static RAM data memory. 8.4 On-chip ROM The 8 kB on-chip ROM contains the boot loader and the following Application Programming Interfaces (API): • In-System Programming (ISP) and In-Application Programming (IAP) support for flash programming • Power profiles for configuring power consumption and PLL settings • USART driver API routines • I2C-bus driver API routines 8.5 Nested Vectored Interrupt Controller (NVIC) The Nested Vectored Interrupt Controller (NVIC) is an integral part of the Cortex-M0+. The tight coupling to the CPU allows for low interrupt latency and efficient processing of late arriving interrupts. 8.5.1 Features • Controls system exceptions and peripheral interrupts. • On the LPC81xM, the NVIC supports 32 vectored interrupts including up to 8 external interrupt inputs selectable from all GPIO pins. • Four programmable interrupt priority levels with hardware priority level masking. • Software interrupt generation using the ARM exceptions SVCall and PendSV. • Relocatable interrupt vector table using vector table offset register. 8.5.2 Interrupt sources Each peripheral device has one interrupt line connected to the NVIC but may have several interrupt flags. Individual interrupt flags may also represent more than one interrupt source. LPC81XM All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2018.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller Up to eight pins, regardless of the selected function, can be programmed to generate an interrupt on a level, a rising or falling edge, or both. The interrupt generating pins can be selected from all digital or mixed digital/analog pins. The pin interrupt/pattern match block controls the edge or level detection mechanism. 8.6 System tick timer The ARM Cortex-M0+ includes a 24-bit system tick timer (SysTick) that is intended to generate a dedicated SysTick exception at a fixed time interval (typically 10 ms). 8.7 Memory map The LPC81xM incorporates several distinct memory regions. Figure7 shows the overall map of the entire address space from the user program viewpoint following reset. The interrupt vector area supports address remapping. The ARM private peripheral bus includes the ARM core registers for controlling the NVIC, the system tick timer (SysTick), and the reduced power modes.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller • Program the input glitch filter with different filter constants using one of the IOCON divided clock signals (IOCONCLKCDIV, see Figure 10 “LPC81xM clock generation”). You can also bypass the glitch filter. • Invert the input signal. • Hysteresis can be enabled or disabled. • For pins PIO0_10 and PIO0_11, select the I2C-mode and output driver for standard digital operation, for I2C standard and fast modes, or for I2C Fast mode+. • On mixed digital/analog pins, enable the analog input mode. Enabling the analog mode disconnects the digital functionality. Remark: The functionality of each I/O pin is flexible and is determined entirely through the switch matrix. See Section8.9 for details. 8.8.1 Standard I/O pad configuration Figure8 shows the possible pin modes for standard I/O pins with analog input function: • Digital output driver with configurable open-drain output • Digital input: Weak pull-up resistor (PMOS device) enabled/disabled • Digital input: Weak pull-down resistor (NMOS device) enabled/disabled • Digital input: Repeater mode enabled/disabled • Digital input: Input glitch filter selectable on all pins • Analog input LPC81XM All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2018.

Standard I/O pad configuration 8.9 Switch Matrix (SWM) The switch matrix controls the function of each digital or mixed analog/digital pin in a highly flexible way by allowing to connect many functions like the USART, SPI, SCT, and I2C functions to any pin that is not power or ground. These functions are called movable functions and are listed in Table5. Functions that need specialized pads like the oscillator pins XTALIN and XTALOUT can be enabled or disabled through the switch matrix. These functions are called fixed-pin functions and cannot move to other pins. The fixed-pin functions are listed in Table4. If a fixed-pin function is disabled, any other movable function can be assigned to this pin. 8.10 Fast General-Purpose parallel I/O (GPIO) Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs can be set or cleared in one write operation. LPC81xM use accelerated GPIO functions: • GPIO registers are located on the ARM Cortex M0+ IO bus for fastest possible single-cycle I/O timing, allowing GPIO toggling with rates of up to 15 MHz.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller • An entire port value can be written in one instruction. • Mask, set, and clear operations are supported for the entire port. All GPIO port pins are fixed-pin functions that are enabled or disabled on the pins by the switch matrix. Therefore each GPIO port pin is assigned to one specific pin and cannot be moved to another pin. Except for pins SWDIO/PIO0_2, SWCLK/PIO0_3, and RESET/PIO0_5, the switch matrix enables the GPIO port pin function by default. 8.10.1 Features • Bit level port registers allow a single instruction to set and clear any number of bits in one write operation. • Direction control of individual bits. • All I/O default to inputs with internal pull-up resistors enabled after reset - except for the I2C-bus true open-drain pins PIO0_2 and PIO0_3. • Pull-up/pull-down configuration, repeater, and open-drain modes can be programmed through the IOCON block for each GPIO pin (see Figure8). • 8.11 Pin interrupt/pattern match engine The pin interrupt block configures up to eight pins from all digital pins for providing eight external interrupts connected to the NVIC. The pattern match engine can be used, in conjunction with software, to create complex state machines based on pin inputs. Any digital pin, independently of the function selected through the switch matrix, can be configured through the SYSCON block as input to the pin interrupt or pattern match engine. The registers that control the pin interrupt or pattern match engine are located on the IO+ bus for fast single-cycle access. 8.11.1 Features • Pin interrupts – Up to eight pins can be selected from all digital pins as edge- or level-sensitive interrupt requests. Each request creates a separate interrupt in the NVIC. – Edge-sensitive interrupt pins can interrupt on rising or falling edges or both. – Level-sensitive interrupt pins can be HIGH- or LOW-active. – Pin interrupts can wake up the LPC81xM from sleep mode, deep-sleep mode, and power-down mode. • Pin interrupt pattern match engine – Up to eight pins can be selected from all digital pins to contribute to a boolean expression. The boolean expression consists of specified levels and/or transitions on various combinations of these pins. – Each minterm (product term) comprising the specified boolean expression can generate its own, dedicated interrupt request. – Any occurrence of a pattern match can be programmed to also generate an RXEV notification to the ARM CPU. The RXEV signal can be connected to a pin. LPC81XM All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2018. All rights reserved.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller • Data frames of 1 to 16 bits supported directly. Larger frames supported by software. • Master and slave operation. • Data can be transmitted to a slave without the need to read incoming data. This can be useful while setting up an SPI memory. • Control information can optionally be written along with data. This allows very versatile operation, including “any length” frames. • One Slave Select input/output with selectable polarity and flexible usage. Remark: Texas Instruments SSI and National Microwire modes are not supported. 8.14 I2C-bus interface The I2C-bus is bidirectional for inter-IC control using only two wires: a serial clock line (SCL) and a serial data line (SDA). Each device is recognized by a unique address and can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the capability to both receive and send information (such as memory). Transmitters and/or receivers can operate in either master or slave mode, depending on whether the chip has to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be controlled by more than one bus master connected to it. The I2C-bus functions are movable functions and can be assigned through the switch matrix to any pin. However, only the true open-drain PIO0_10 and PIO0_11 provide the electrical characteristics to support the full I2C-bus specification (see Ref.1). 8.14.1 Features • Supports standard and fast mode with data rates of up to 400 kbit/s. • Independent Master, Slave, and Monitor functions. • Supports both Multi-master and Multi-master with Slave functions. • Multiple I2C slave addresses supported in hardware. • One slave address can be selectively qualified with a bit mask or an address range in order to respond to multiple I2C bus addresses. • 10-bit addressing supported with software assist. • Supports SMBus. • Supported by on-chip ROM API. • If the I2C functions are connected to the true open-drain pins (PIO0_10 and PIO0_11), the I2C supports the full I2C-bus specification: – Fail-safe operation: When the power to an I2C-bus device is switched off, the SDA and SCL pins connected to the I2C-bus are floating and do not disturb the bus. – Supports Fast-mode Plus with bit rates up to 1 Mbit/s. 8.15 State-Configurable Timer/PWM (SCTimer/PWM) The state configurable timer (SCTimer/PWM or SCT) can perform basic 16-bit and 32-bit timer/counter functions with match outputs and external and internal capture inputs. In addition, the SCTimer/PWM can employ up to two different programmable states, which can change under the control of events, to provide complex timing patterns.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller All inputs and outputs of the SCTimer/PWM are movable functions and are assigned to pins through the switch matrix. 8.15.1 Features • Two 16-bit counters or one 32-bit counter. • Counters clocked by bus clock or selected input. • Up counters or up-down counters. • State variable allows sequencing across multiple counter cycles. • The following conditions define an event: a counter match condition, an input (or output) condition, a combination of a match and/or and input/output condition in a specified state, and the count direction. • Events control outputs, interrupts, and the SCT states. – Match register 0 can be used as an automatic limit. – In bi-directional mode, events can be enabled based on the count direction. – Match events can be held until another qualifying event occurs. • Selected events can limit, halt, start, or stop a counter. • Supports: – 4 inputs – 4 outputs – 5 match/capture registers – 6 events – 2 states 8.16 Multi-Rate Timer (MRT) The Multi-Rate Timer (MRT) provides a repetitive interrupt timer with four channels. Each channel can be programmed with an independent time interval, and each channel operates independently from the other channels. 8.16.1 Features • 31-bit interrupt timer • Four channels independently counting down from individually set values • Bus stall, repeat and one-shot interrupt modes 8.17 Windowed WatchDog Timer (WWDT) The watchdog timer resets the controller if software fails to periodically service it within a programmable time window. 8.17.1 Features • Internally resets chip if not periodically reloaded during the programmable time-out period. • Optional windowed operation requires reload to occur between a minimum and maximum time period, both programmable.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller • Optional warning interrupt can be generated at a programmable time prior to watchdog time-out. • Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled. • Incorrect feed sequence causes reset or interrupt if enabled. • Flag to indicate watchdog reset. • Programmable 24-bit timer with internal prescaler. • Selectable time period from (T 2564) to (T 2244) in cy(WDCLK) cy(WDCLK) multiples of T 4. cy(WDCLK) • The Watchdog Clock (WDCLK)is generated by a the dedicated watchdog oscillator (WDOSC). 8.18 Self Wake-up Timer (WKT) The self wake-up timer is a 32-bit, loadable down-counter. Writing any non-zero value to this timer automatically enables the counter and launches a count-down sequence. When the counter is used as a wake-up timer, this write can occur just prior to entering a reduced power mode. 8.18.1 Features • 32-bit loadable down-counter. Counter starts automatically when a count value is loaded. Time-out generates an interrupt/wake up request. • The WKT resides in a separate, always-on power domain. • The WKT supports two clock sources: the low-power oscillator and the IRC. The low-power oscillator is located in the always-on power domain, so it can be used as the clock source in Deep power-down mode. • The WKT can be used for waking up the part from any reduced power mode, including Deep power-down mode, or for general-purpose timing. 8.19 Analog comparator (ACMP) The analog comparator with selectable hysteresis can compare voltage levels on external pins and internal voltages. After power-up and after switching the input channels of the comparator, the output of the voltage ladder must be allowed to settle to its stable value before it can be used as a comparator reference input. Settling times are given in Table23. The analog comparator output is a movable function and is assigned to a pin through the switch matrix. The comparator inputs and the voltage reference are enabled or disabled on pins PIO0_0 and PIO0_1 through the switch matrix.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller Each oscillator, except the low-frequency oscillator, can be used for more than one purpose as required in a particular application. Following reset, the LPC81xM will operate from the IRC until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure10 for an overview of the LPC81xM clock generation. 8.20.1.1 Internal RC Oscillator (IRC) The IRC may be used as the clock source for the WWDT, and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC frequency is 12MHz. The IRC is trimmed to 1.5% accuracy over the entire voltage and temperature range. The IRC can be used as a clock source for the CPU with or without using the PLL. The IRC frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. Upon power-up or any chip reset, the LPC81xM use the IRC as the clock source. Software may later switch to one of the other available clock sources. 8.20.1.2 Crystal Oscillator (SysOsc) The crystal oscillator can be used as the clock source for the CPU, with or without using the PLL. The SysOsc operates at frequencies of 1MHz to 25MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. 8.20.1.3 Internal Low-power Oscillator and Watchdog Oscillator (WDOsc) The nominal frequency of the WDOsc is programmable between 9.4 kHz and 2.3 MHz. The frequency spread over silicon process variations is 40%. The WDOsc is a dedicated oscillator for the windowed WWDT. The internal low-power 10 kHz ( 40% accuracy) oscillator serves a the clock input to the WKT. This oscillator can be configured to run in all low power modes. 8.20.2 Clock input An external clock source can be supplied on the selected CLKIN pin. When selecting a clock signal for the CLKIN pin, follow the specifications for digital I/O pins in Table 9 “Static characteristics” and Table 16 “Dynamic characteristics: I/O pins[1]”. An 1.8V external clock source can be supplied on the XTALIN pins to the system oscillator limiting the voltage of this signal ((see Section14.2). The maximum frequency for both clock signals is 25 MHz. 8.20.3 System PLL The PLL accepts an input clock frequency in the range of 10MHz to 25MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156MHz to 320MHz, so there is an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is insured that the PLL output has a 50% duty cycle. The PLL is turned off and bypassed following a chip reset and may be enabled by software. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is nominally 100s. 8.20.4 Clock output The LPC81xM features a clock output function that routes the IRC, the SysOsc, the watchdog oscillator, or the main clock to the CLKOUT function. The CLKOUT function can be connected to any digital pin through the switch matrix. 8.20.5 Wake-up process The LPC81xM begin operation at power-up by using the IRC as the clock source. This allows chip operation to resume quickly. If the SysOsc, the external clock source, or the PLL is needed by the application, software must enable these features and wait for them to stabilize before they are used as a clock source. 8.20.6 Power control The LPC81xM supports the ARM Cortex-M0 Sleep mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, a register is provided for shutting down the clocks to individual on-chip peripherals, allowing to fine-tune power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Selected peripherals have their own clock divider which provides even better power control. 8.20.6.1 Power profiles The power consumption in Active and Sleep modes can be optimized for the application through simple calls to the power profile API. The API is accessible through the on-chip ROM. The power configuration routine configures the LPC81xM for one of the following power modes: • Default mode corresponding to power configuration after reset. • CPU performance mode corresponding to optimized processing capability. • Efficiency mode corresponding to optimized balance of current consumption and CPU performance. • Low-current mode corresponding to lowest power consumption. In addition, the power profile includes routines to select the optimal PLL settings for a given system clock and PLL input clock. 8.20.6.2 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller In Sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 8.20.6.3 Deep-sleep mode In Deep-sleep mode, the LPC81xM is in Sleep-mode and all peripheral clocks and all clock sources are off except for the IRC and watchdog oscillator or low-power oscillator if selected. The IRC output is disabled. In addition all analog blocks are shut down and the flash is in stand-by mode. In Deep-sleep mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC81xM can wake up from Deep-sleep mode via a reset, digital pins selected as inputs to the pin interrupt block, a watchdog timer interrupt, or an interrupt from the USART (if the USART is configured in synchronous slave mode), the SPI, or the I2C blocks (in slave mode). Any interrupt used for waking up from Deep-sleep mode must be enabled in one of the SYSCON wake-up enable registers and the NVIC. Deep-sleep mode saves power and allows for short wake-up times. 8.20.6.4 Power-down mode In Power-down mode, the LPC81xM is in Sleep-mode and all peripheral clocks and all clock sources are off except for watchdog oscillator or low-power oscillator if selected. In addition all analog blocks and the flash are shut down. In Power-down mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC81xM can wake up from Power-down mode via a reset, digital pins selected as inputs to the pin interrupt block, a watchdog timer interrupt, or an interrupt from the USART (if the USART is configured in synchronous slave mode), the SPI, or the I2C blocks (in slave mode). Any interrupt used for waking up from Power-down mode must be enabled in one of the SYSCON wake-up enable registers and the NVIC. Power-down mode reduces power consumption compared to Deep-sleep mode at the expense of longer wake-up times. 8.20.6.5 Deep power-down mode In Deep power-down mode, power is shut off to the entire chip except for the WAKEUP pin and the self wake-up timer if enabled. Four general-purpose registers are available to store information during Deep power-down mode. The LPC81xM can wake up from Deep power-down mode via the WAKEUP pin, or without an external signal by using the time-out of the self wake-up timer (see Section8.18). The LPC81xM can be prevented from entering Deep power-down mode by setting a lock bit in the PMU block. Locking out Deep power-down mode enables the application to keep the watchdog timer or the BOD running at all times.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller When entering Deep power-down mode, an external pull-up resistor is required on the WAKEUP pin to hold it HIGH. Pull the RESET pin HIGH to prevent it from floating while in Deep power-down mode. 8.21 System control 8.21.1 Reset Reset has four sources on the LPC81xM: the RESET pin, the Watchdog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage attains a usable level, starts the IRC and initializes the flash controller. A LOW-going pulse as short as 50 ns resets the part. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. In Deep power-down mode, an external pull-up resistor is required on the RESET pin.

Reset pad configuration 8.21.2 Brownout detection The LPC81xM includes up to four levels for monitoring the voltage on the V pin. If this DD voltage falls below one of the selected levels, the BOD asserts an interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC to cause a CPU interrupt. Alternatively, software can monitor the signal by reading a dedicated status register. Four threshold levels can be selected to cause a forced reset of the chip. LPC81XM All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2018.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 8.21.3 Code security (Code Read Protection - CRP) CRP provides different levels of security in the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD) and In-System Programming (ISP) can be restricted. Programming a specific pattern into a dedicated flash location invokes CRP. IAP commands are not affected by the CRP. In addition, ISP entry via the ISP entry pin can be disabled without enabling CRP. For details, see the LPC800 user manual. There are three levels of Code Read Protection: 1. CRP1 disables access to the chip via the SWD and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors cannot be erased. 2. CRP2 disables access to the chip via the SWD and only allows full flash erase and update using a reduced set of the ISP commands. 3. Running an application with level CRP3 selected, fully disables any access to the chip via the SWD pins and the ISP. This mode effectively disables ISP override using the ISP entry pin as well. If necessary, the application must provide a flash update mechanism using IAP calls or using a call to the reinvoke ISP command to enable flash update via the USART. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device. In addition to the three CRP levels, sampling of the ISP entry pin for valid user code can be disabled. For details, see the LPC800 user manual. 8.21.4 APB interface The APB peripherals are located on one APB bus. 8.21.5 AHBLite The AHBLite connects the CPU bus of the ARM Cortex-M0+ to the flash memory, the main static RAM, the CRC, and the ROM.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 8.22 Emulation and debugging Debug functions are integrated into the ARM Cortex-M0+. Serial wire debug functions are supported in addition to a standard JTAG boundary scan. The ARM Cortex-M0+ is configured to support up to four breakpoints and two watch points. The Micro Trace Buffer is implemented on the LPC81xM. The RESET pin selects between the JTAG boundary scan (RESET = LOW) and the ARM SWD debug (RESET = HIGH). The ARM SWD debug port is disabled while the LPC81xM is in reset. The JTAG boundary scan pins are selected by hardware when the part is in boundary scan mode on pins PIO0_0 to PIO0_3 (see Table4). To perform boundary scan testing, follow these steps: 1. Erase any user code residing in flash. 2. Power up the part with the RESET pin pulled HIGH externally. 3. Wait for at least 250 s. 4. Pull the RESET pin LOW externally. 5. Perform boundary scan operations. 6. Once the boundary scan operations are completed, assert the TRST pin to enable the SWD debug mode, and release the RESET pin (pull HIGH). Remark: The JTAG interface cannot be used for debug purposes.

Thermal characteristics The average chip junction temperature, T (C), can be calculated using the following j equation: Tj = Tamb+PDRthj–a (1) • T = ambient temperature (C), amb • R = the package junction-to-ambient thermal resistance (C/W) th(j-a) • P = sum of internal and I/O power dissipation D The internal power dissipation is the product of I and V . The I/O power dissipation of DD DD the I/O pins is often small and many times can be negligible. However it can be significant in some applications. Table 8.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 11.3 Peripheral power consumption The supply current per peripheral is measured as the difference in supply current between the peripheral block enabled and the peripheral block disabled in the SYSAHBCLKCFG and PDRUNCFG (for analog blocks) registers. All other blocks are disabled in both registers and no code is executed. Measured on a typical sample at T =25 C. Unless amb noted otherwise, the system oscillator and PLL are running in both measurements. The supply currents are shown for system clock frequencies of 12 MHz and 30 MHz. Table 10.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller [3] t is the data hold time that is measured from the falling edge of SCL; applies to data in transmission HD;DAT and the acknowledge. [4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the V (min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. IH [5] C = total capacitance of one bus line in pF. b [6] The maximum t for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA f output stage t is specified at 250 ns. This allows series protection resistors to be connected in between the f SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified t. f [7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of t or t by a transition time (see UM10204). This maximum must only be met if VD;DAT VD;ACK the device does not stretch the LOW period (t ) of the SCL signal. If the clock stretches the SCL, the LOW data must be valid by the set-up time before it releases the clock. [9] t is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in SU;DAT transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement t =250 ns must then be met. This will automatically be the case if the device does not stretch the SU;DAT LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line t + t = 1000 + 250 = 1250 ns (according to the r(max) SU;DAT Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time.

[2] IRC enabled, all peripherals off. [3] Watchdog oscillator disabled, Brown-Out Detect (BOD) disabled. [4] Self wakeup-timer disabled. Wake-up from deep power-down causes the LPC800 to go through entire reset process. The wake-up time measured is the time between when a wake-up pin is triggered to wake the device up from the low power modes and from when a GPIO output pin is set in the reset handler. 14.2 XTAL input The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with C = 100 pF. To limit the input voltage to the specified range, choose an additional i capacitor to ground C which attenuates the input voltage by a factor C/(C + C ). In slave g i i g mode, a minimum of 200 mV(RMS) is needed.

Slave mode operation of the on-chip oscillator In slave mode the input clock signal should be coupled by means of a capacitor of 100pF (Figure36), with an amplitude between 200mV (RMS) and 1000mV (RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure37 and in Table26 and Table27. Since the feedback resistance is integrated on chip, only a crystal and the capacitances C and C need to be connected externally in case of X1 X2 fundamental mode oscillation (the fundamental frequency is represented by L, C and L LPC81XM All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2018.

LPC81xM NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 14.3 XTAL Printed Circuit Board (PCB) layout guidelines The crystal should be connected on the PCB as close as possible to the oscillator input and output pins of the chip. Take care that the load capacitors C ,C , and C in case of x1 x2 x3 third overtone crystal usage have a common ground plane. The external components must also be connected to the ground plain. Loops must be made as small as possible in order to keep the noise coupled in via the PCB as small as possible. Also parasitics should stay as small as possible. Values of C and C should be chosen smaller x1 x2 accordingly to the increase in parasitics of the PCB layout.
