CC2531BlockDiagram A block diagram of the CC2531 is shown in Figure 7.

In the following subsections, a short description of each module that appears in Figure7isgiven. 18 SubmitDocumentationFeedback Copyright©2009–2010,TexasInstrumentsIncorporated ProductFolderLink(s):CC2531F128 CC2531F256

CC2531F128, CC2531F256 www.ti.com SWRS086A–SEPTEMBER2009–REVISEDJUNE2010 For more details about the modules and their usage, see the corresponding chapters in the CC253x User's Guide(SWRU191). CPUandMemory The 8051 CPU core used in the CC253x device family is a single-cycle 8051-compatible core. It has three different memory-access buses (SFR, DATA, and CODE/XDATA) with single-cycle access to SFR, DATA, and themainSRAM.Italsoincludesadebuginterfaceandan18-inputextendedinterruptunit. The interrupt controller services a total of 18 interrupt sources, divided into six interrupt groups, each of which is associated with one of four interrupt priorities. Any interrupt service request is serviced also when the device is in idle mode by going back to active mode. Some interrupts can also wake up the device from sleep mode (powermodes1–3). The memory arbiter is at the heart of the system, as it connects the CPU and DMA controller with the physical memories and all peripherals through the SFR bus. The memory arbiter has four memory access points, access of which can map to one of three physical memories: an 8-KB SRAM, flash memory, and XREG/SFR registers. It is responsible for performing arbitration and sequencing between simultaneous memory accesses to the same physicalmemory. The 8-KB SRAM maps to the DATA memory space and to parts of the XDATA memory spaces. The 8-KB SRAM is an ultralow-power SRAM that retains its contents even when the digital part is powered off (power modes2and3).Thisisanimportantfeatureforlow-powerapplications. The 256 KB flash block provides in-circuit programmable non-volatile program memory for the device, and maps into the CODE and XDATA memory spaces. In addition to holding program code and constants, the non-volatile memory allows the application to save data that must be preserved such that it is available after restartingthedevice.Usingthisfeatureonecan,e.g.,usesavednetwork-specificdatatoavoidtheneedforafull start-upandnetworkfind-and-joinprocess. ClocksandPowerManagement The digital core and peripherals are powered by a 1.8-V low-dropout voltage regulator. It provides power management functionality that enables low-power operation for long battery life using different power modes. Fivedifferentresetsourcesexisttoresetthedevice. Peripherals The CC2531 includes many different peripherals that allow the application designer to develop advanced applications. The debug interface implements a proprietary two-wire serial interface that is used for in-circuit debugging. Through this debug interface, it is possible to perform an erasure of the entire flash memory, control which oscillators are enabled, stop and start execution of the user program, execute supplied instructions on the 8051 core, set code breakpoints, and single-step through instructions in the code. Using these techniques, it is possibletoperformin-circuitdebuggingandexternalflashprogrammingelegantly. The device contains flash memory for storage of program code. The flash memory is programmable from the user software and through the debug interface. The flash controller handles writing and erasing the embedded flashmemory.Theflashcontrollerallowspage-wiseerasureand4-bytewiseprogramming. The I/O controller is responsible for all general-purpose I/O pins. The CPU can configure whether peripheral modulescontrolcertainpinsorwhethertheyareundersoftwarecontrol,andifso,whethereachpinisconfigured as an input or output and if a pullup or pulldown resistor in the pad is connected. CPU interrupts can be enabled on each pin individually. Each peripheral that connects to the I/O pins can choose between two different I/O pin locationstoensureflexibilityinvariousapplications. A versatile five-channel DMA controller is available in the system, accesses memory using the XDATA memory space, and thus has access to all physical memories. Each channel (trigger, priority, transfer mode, addressing mode, source and destination pointers, and transfer count) is configured with DMA descriptors anywhere in memory. Many of the hardware peripherals (AES core, flash controller, USARTs, timers, ADC interface) achieve highly efficient operation by using the DMA controller for data transfers between SFR or XREG addresses and flash/SRAM.

CC2531F128, CC2531F256 SWRS086A–SEPTEMBER2009–REVISEDJUNE2010 www.ti.com Timer 1 is a 16-bit timer with timer/counter/PWM functionality. It has a programmable prescaler, a 16-bit period value, and five individually programmable counter/capture channels, each with a 16-bit compare value. Each of the counter/capture channels can be used as a PWM output or to capture the timing of edges on input signals. It can also be configured in IR Generation Mode, where it counts Timer 3 periods and the output is ANDed with theoutputofTimer3togeneratemodulatedconsumerIRsignalswithminimalCPUinteraction. Timer 2 (the MAC Timer) is specially designed for supporting an IEEE 802.15.4 MAC or other time-slotted protocol in software. The timer has a configurable timer period and a 24-bit overflow counter that can be used to keep track of the number of periods that have transpired. A 40-bit capture register is also used to record the exact time at which a start-of-frame delimiter is received/transmitted or the exact time at which transmission ends, as well as two 16-bit output compare registers and two 24-bit overflow compare registers that can send variouscommandstrobes(startRX,startTX,etc.)atspecifictimestotheradiomodules. Timer 3 and Timer 4 are 8-bit timers with timer/counter/PWM functionality. They have a programmable prescaler, an 8-bit period value, and one programmable counter channel with an 8-bit compare value. Each of thecounterchannelscanbeusedasaPWMoutput. The sleep timer is an ultralow-power timer that counts 32-kHz crystal oscillator or 32-kHz RC oscillator periods. The sleep timer runs continuously in all operating modes except power mode 3 (PM3). Typical applications of thistimerareasareal-timecounterorasawake-uptimertocomeoutofpowermode1(PM1)or2(PM2). The ADC supports 7 to 12 bits of resolution in a 30-kHz to 4-kHz bandwidth, respectively. DC and audio conversions with up to eight input channels (Port 0) are possible. The inputs can be selected as single-ended or differential. The reference voltage can be internal, AVDD, or a single-ended or differential external signal. The ADC also has a temperature-sensor input channel. The ADC can automate the process of periodic sampling or conversionoverasequenceofchannels. The random-number generator uses a 16-bit LFSR to generate pseudorandom numbers, which can be read by theCPUoruseddirectlybythecommandstrobeprocessor.Itcanbeseededwithrandomdatafromnoiseinthe radioADC. The AES encryption/decryption core allows the user to encrypt and decrypt data using the AES algorithm with 128-bit keys. The core is able to support the AES operations required by IEEE 802.15.4 MAC security, the ZigBeenetworklayer,andtheapplicationlayer. A built-in watchdog timer allows the CC2531 to reset itself in case the firmware hangs. When enabled by software,thewatchdogtimermustbeclearedperiodically;otherwise,itresetsthedevicewhenittimesout.Itcan alternativelybeconfiguredforuseasageneral32-kHztimer. USART 0 and USART 1 are each configurable as either a SPI master/slave or a UART. They provide double buffering on both RX and TX and hardware flow control, and are thus well suited to high-throughput full-duplex applications. Each has its own high-precision baud-rate generator, thus leaving the ordinary timers free for other uses. The USB device operates at full-speed, 12-Mbps transfer rate. The controller has 5 bidirectional endpoints in addition to control endpoint 0. The endpoints support bulk, interrupt, and isochronous operation for implementation of a wide range of applications. The 1024 bytes of dedicated, flexible FIFO memory combined withDMAaccessensuresthataminimumofCPUinvolvementisneededforUSBcommunication. Radio The CC2531 features an IEEE 802.15.4-compliant radio transceiver. The RF core controls the analog radio modules. In addition, it provides an interface between the MCU and the radio which makes it possible to issue commands, read status, and automate and sequence radio events. The radio also includes a packet-filtering and address-recognitionmodule. 20 SubmitDocumentationFeedback Copyright©2009–2010,TexasInstrumentsIncorporated ProductFolderLink(s):CC2531F128 CC2531F256

CC2531F128, CC2531F256 SWRS086A–SEPTEMBER2009–REVISEDJUNE2010 www.ti.com APPLICATION INFORMATION Few external components are required for the operation of the CC2531. A typical application circuit is shown in Figure 18. For a complete USB-certified reference design, see the CC2531 product page on www.ti.com. Typical values and description of external components are shown in Table 2. The USB_P and USB_N pins need series resistors R21 and R31 for impedance matching, and the D+ line must have a pullup resistor, R32. The series resistors should match the 90 Ω ±15% characteristic impedance of the USB bus. Notice that the pullup resistor and DVDD_USB must be connected to a voltage source between 3 V and 3.6 V (typically 3.3 V). The voltage source should be derived from or controlled by the VBUS power supply provided by the USB cable. In this way, the pullup resistor does not provide current to the D+ line when VBUS is removed. The pullup resistor may be connected directly between VBUS and the D+ line. As an alternative, if the CC2531 firmware needs the ability to disconnectfromtheUSBbus,aGPIOontheCC2531canbeusedtocontrolthepullupresistor.
