PCA8547 4 x 44 automotive LCD driver with integrated charge pump Rev. 2 — 7 April 2015 Product data sheet 1. General description The PCA8547 is a fully featured Liquid Crystal Display (LCD)1 driver, specifically designed for high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:4. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes, 44segments, and up to 176elements. The PCA8547 features an internal charge pump with internal capacitors for on-chip generation of the LCD driving voltage. To ensure an optimal and stable contrast over the full temperature range, the PCA8547 offers a programmable temperature compensation of the LCD supply voltage. The PCA8547 can be easily connected to a microcontroller by either the two-line I2C-bus (PCA8547A) or a three-line bidirectional SPI-bus (PCA8547B). For a selection of NXP LCD segment drivers, see Table43 on page66. 2.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 8.1.1 Command: Initialize This command generates a chip-wide reset. It consists of two bytes which have to be sent both to the device. Table 6. Initialize - initialize command bit description For further information, see Section8.2 on page16. Bit Symbol Value Description Initialize-MSB 7 to 0 - 00111010 fixed value Initialize-LSB 7 to 0 - 00000100 fixed value 8.1.2 Command: OTP-refresh During production and testing of the device, each IC is calibrated to achieve the specified accuracy of V , the frame frequency, and the temperature measurement. This LCD calibration is performed on EPROM cells called One Time Programmable (OTP) cells. The device reads these cells every time at power-on, after a reset, and every time when the initialize command or the OTP-refresh command is sent. Remark: It is recommended not to enter power-down mode during the OTP refresh cycle. Table 7.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 8.1.3.1 Oscillator The internal logic and LCD drive signals of the PCA8547 are timed either by the built-in oscillator or from an external clock. 8.1.3.2 Internal oscillator When the internal oscillator is used, it is possible to make the clock signal available on pin CLK by using the Oscillator-ctrl command (see Table8). If this is not intended, the pin CLK should be left open. At power-on the signal at pin CLK is disabled and pin CLK is in 3-state. If the internal charge pump is enabled, then the internal oscillator starts and is used to run the charge pump. An external oscillator can still be applied for driving the display waveforms. The duty cycle of the output clock provided on the CLK pin is not always 50:50. Table18 on page13 shows the expected duty cycle for each of the chosen frame frequencies. 8.1.3.3 External clock In applications where an external clock must be applied to the PCA8547, bit OSC (see Table8) must be set logic1. In this case, pin CLK becomes an input. The CLK signal is a signal that is fed into the V domain. Therefore it must have an DD1 amplitude equal to the V voltage supplied to the chip and be referenced to V . DD1 SS The clock frequency (f ) determines the LCD frame frequency. clk Remark: If an external clock is used then this clock signal must always be supplied to the device. Removing the clock can freeze the LCD in a DC state. Removal of the clock is possible when following the correct procedures (see Figure11 on page21 and Figure12 on page22). 8.1.4 Command: Charge-pump-ctrl The Charge-pump-ctrl command enables or disables the internal V generation and LCD controls the charge pump voltage multiplier setting.

[2] Duty cycle definition: %HIGH-level time: %LOW-level time. [3] Default value. 8.1.12.1 Timing and frame frequency The timing of the PCA8547 organizes the internal data flow of the device. This includes the transfer of display data from the display RAM to the display segment outputs. The timing also generates the LCD frame frequency. The frame frequency is a fixed division of the internal clock or of the frequency applied to pin CLK when an external clock is used. When the internal clock is used, the clock frequency can be programmed by software such that the nominal frame frequency can be chosen in steps of 10Hz in the range of 60Hz to 300Hz (see Table18). Furthermore the nominal frame frequency is factory-calibrated with an accuracy of ±15%. When the internal clock is enabled at pin CLK by using bit COE, the duty ratio of the clock may change when choosing different values for the frame frequency prescaler. Table18 shows the different output duty ratios for each frame frequency prescaler setting. 8.1.13 Command: Bank-select The PCA8547 allows writing data to one area of the RAM while displaying from another. These areas are named RAM banks. There are two banks, 0and1. Figure33 on page43 and Figure34 on page43 show the concept. The Bank-select command controls where data is written to and where it is displayed from.

Bit Symbol Binary value Description 7 to 2 - 000010 fixed value 1 IBS selects RAM bank to write to 0[1] Bank 0 1 Bank 1 0 OBS selects RAM bank to read from to the LCD 0[1] Bank 0 1 Bank 1 [1] Default value. 8.1.14 Command: Write-RAM-data By setting the RS bit of the control byte to logic1, all data transferred is interpreted as RAM data and placed in the RAM in accordance with the current setting of the RAM address pointer (see Section8.1.11 on page13). Definition of the RS can be found in Table31 on page45. Remark: After Power-On Reset (POR) the RAM content is random and should be brought to a defined status by clearing it (setting it to logic0).

Bit Symbol Binary value Description 7 to 0 B[7:0] 00000000 to writing data byte-wise to the RAM 11111111 8.1.15 Command: Temp-read The Temp-read command allows reading out the temperature values measured by the internal temperature sensor. Table 21. Temp-read - temperature readout command bit description For further information, see Section8.4.4 on page28. Bit Symbol Binary value Description 7 to 0 TD[7:0] 00000000 to digital temperature values[1] 11111111 [1] For this command, bit R/W of the I2C-bus slave address byte has to be set logic1 (see Table32). 8.1.16 Command: Invmode_ctrl The Invmode_ctrl command allows changing the drive scheme inversion mode. The waveforms used to drive LCD displays inherently produce a DC voltage across the display cell. The PCA8547 compensates for the DC voltage by inverting the waveforms on alternate frames or alternate lines. The choice of compensation method is determined with the LF bit.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump Table 22. Invmode_ctrl - drive scheme inversion command bit description For further information, see Section8.4.6 on page34. Bit Symbol Binary value Description 7 to 2 - 110101 fixed value 1 LF set inversion mode 0[1] driving scheme A: line inversion mode 1 driving scheme B: frame inversion mode 0 - 0 fixed value [1] Default value. In frame inversion mode, the DC value is compensated across two frames and not within one frame. Changing the inversion mode to frame inversion reduces the power consumption, therefore it is useful when power consumption is a key point in the application. Frame inversion may not be suitable for all applications. The RMS voltage across a segment is better defined, however since the switching frequency is reduced there is possibility for flicker to occur. Figure24 on page34 to Figure27 on page37 are showing the waveforms in line inversion mode. 8.1.17 Command: Temp-filter Table 23. Temp-filter - digital temperature filter command bit description For further information, see Section8.4.4 on page28.

After a reset and the initialization the starting conditions of the PCA8547 are as follows: 1. All backplane and segment outputs are set to V . SS 2. Selected drive mode is: 1:4 with 1⁄ bias. 4 3. Input and output bank selectors are reset. 4. The I2C-bus and SPI-bus interface are initialized. 5. The data pointer is cleared (set logic0).

The first command sent to the device after the power-on or reset event must be the Initialize command (see Section8.1.1). After POR and before enabling the display, the RAM content should be brought to a defined status • by clearing it (setting it all to logic0) or • by writing meaningful content (for example, a graphic) otherwise unwanted display artifacts may appear on the display.

Recommended power-down sequence for minimum power-down current when using an external supplied V and an external clock signal LCD Remark: It is necessary to run the power-down sequence before removing the supplies. Depending on the application, care must be taken that no other signals are present at the chip input or output pins when removing the supplies (see Section10). Otherwise this may cause unwanted display artifacts. In the case of uncontrolled removal of supply voltages the PCA8547 will not be damaged. Remark: Static voltages across the liquid crystal display can build up when the external LCD supply voltage (V ) is on while the IC supply voltage (V or V ) is off, or the LCD DD1 DD2 other way around. This may cause unwanted display artifacts. To avoid such artifacts, V , V , and V must be applied or removed together. LCD DD1 DD2 Remark: A clock signal must always be supplied to the device when the display is active. Removing the clock may freeze the LCD in a DC state, which is not suitable for the liquid crystal. It is recommended to first disable the display and afterwards to remove the clock signal. 8.3 Possible display configurations The PCA8547 is a versatile peripheral device designed to interface between any microcontroller to a wide variety of LCD segment or dot matrix displays (see Figure13). It can directly drive any static or multiplexed LCD containing up to four backplanes with 44segments. The display configurations possible with the PCA8547 depend on the number of active backplane outputs required. A selection of possible display configurations is given in Table25.

DD1 DD2 LCD Fig 15. Typical SPI system configuration when using an external V LCD The host microcontroller maintains the two-line I2C-bus communication channel with the PCA8547A or the three-line SPI-bus with the PCA8547B. The appropriate biasing voltages for the multiplexed LCD waveforms are generated internally. The only other connections required to complete the system are the power supplies (V , V V , DD1 DD2, SS V ), the external capacitors, and the LCD panel selected for the application. LCD The recommended values for external capacitors on V , V , and V are of nominal DD1 DD2 LCD 100nF value. When using bigger capacitors, especially on the V , the generated ripple LCD will be consequently smaller. However it will take longer for the internal charge pump to first reach the target V voltage. LCD If V and V are connected externally, the capacitors on V and V can be DD1 DD2 DD1 DD2 replaced by a single capacitor with a nominal value of 220nF. Remark: In case of insufficient decoupling, ripple on V and V will create additional DD1 DD2 V ripple. The ripple on the V can be reduced by making the V connection as LCD LCD SS low-ohmic as possible. Excessive ripple on V may cause flicker on the display. LCD 8.4 LCD supply voltage 8.4.1 External V supply LCD V can be directly supplied to the VLCD pin. In this case, the internal charge pump must LCD not be enabled otherwise a high current may occur on pin VDD2 and pin VLCD. When V is supplied externally, no internal temperature compensation occurs on this voltage LCD even if bit TCE is set logic1 (see Section8.4.4.2). The V voltage which is supplied LCD externally will be available at the segments and backplanes of the device through the chosen bias system. Also programming VPR[7:0] will have no effect on the V which is LCD externally supplied. 8.4.2 Internal V generation LCD V can be generated and controlled on the chip by using software commands. When LCD the internal charge pump is used, the programmed V is available on pin VLCD. The LCD charge pump generates a V of up to 3V . The charge pump can be enabled or LCD DD2 disabled with the CPE bit (see Table9 on page10). With bit CPC, the charge pump multiplier setting can be configured.

(2) Automatic limitation for V > 9.0V. LCD Fig 17. V programming of PCA8547 (assuming VT[7:0]=0h) LCD The programmable range of VPR[7:0] is from 0h to FFh. With the upper part of the programmable range, it is possible to achieve more than 9.0V, but the PCA8547 has a built-in automatic limitation of V at 9.0V.

DD2 8.4.3 Charge pump 8.4.3.1 Charge pump configuration To obtain the desired V values, the charge pump has to be configured properly. It has LCD to be taken into account that the maximum theoretical values cannot be reached due to internal losses (see Section8.4.3.2). So, for example, it is not possible to get a V =6.0V with V =3.0V and a charge pump configuration of 2times V . In this LCD DD2 DD2 case, a charge pump configuration of 3times V is needed.

Charge pump configuration: V =3V LCD DD2 Fig 19. Charge pump driving capability with V =5.0V DD2 8.4.4 Temperature measurement and temperature compensation of V LCD 8.4.4.1 Temperature readout The PCA8547 has a built-in temperature sensor which provides an 8bit digital value, TD[7:0], of the ambient temperature. This value can be read through the interface (see Figure41 on page49 and Figure45 on page51). The actual temperature is determined from TD[7:0] using Equation2: T (°C) = 0.9375TD7:0–40 (2) The measurement needs about 5ms to complete and is repeated periodically as soon as bit TME is set logic1 (see Table10 on page11). The time between measurements is linked to the system clock and hence varies with changes in the chosen frame frequency, see Table26. Table 26. Temperature measurement update rate Selected frame frequency Temperature measurement update rate 60 Hz 3.3 s 200 Hz 1 s 300 Hz 0.67 s The temperature sensor can be thought of as analog to digital converter. Like all A/D converters, jitter will exist on the LSB of the output value. This is also true of the temperature sensor in the PCA8547.

Temperature measurement delay during ramping up-down of the environment temperature This delay may cause undesired effects at start-up when the environment temperature may be different than the reset value of the PCA8547 which is 20C. In this case, it takes up to 30s until the correct measured temperature value will be available. A control bit, TFE (see Table23 on page16), is implemented to enable or disable the digital temperature filter. This bit is set logic0 by default, which means, that the filter is disabled and the unfiltered environment temperature value is available to calculate the desired V .

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 8.4.4.2 Temperature adjustment of the V LCD Due to the temperature dependency of the liquid crystal viscosity the LCD controlling voltage V might have to be adjusted at different temperatures to maintain optimal LCD contrast. The temperature behavior of the liquid comes from the LCD manufacturer. The slope has to be set to compensate for the liquid behavior. Internal temperature compensation may be enabled via bit TCE (see Table10 on page11). The ambient temperature range is split up into four equally sized regions and a different temperature coefficient can be applied to each. Each coefficient can be selected from a choice of eight different slopes. Each one of these coefficients may be independently selected (see Table27). Table 27.

The device will not permit overflow or underflow and will clamp results to either end of the range. 8.4.5 LCD voltage selector The LCD voltage selector co-ordinates the multiplexing of the LCD in accordance with the selected LCD drive configuration. The operation of the voltage selector is controlled by the Set-bias-mode command (see Table15 on page13) and the Set-MUX-mode command (see Table14 on page12). Intermediate LCD biasing voltages are obtained from an internal voltage divider. The biasing configurations that apply to the preferred modes of operation, together with the biasing characteristics as functions of V and the resulting discrimination ratios(D), are LCD given in Table29. Discrimination is a term which is defined as the ratio of the one and off RMS voltage across a segment. It can be thought of as a measurement of contrast. Table 29.

LCD th 1 Bias is calculated by -------------, where the values for a are 1+a a = 1 for 1⁄ bias 2 a = 2 for 1⁄ bias 3 a = 3 for 1⁄ bias 4 The RMS on-state voltage (V ) for the LCD is calculated with Equation3 on(RMS) a2+2a+n VonRMS = VLCD ----------------------------2-- (3) n1+a where V is the resultant voltage at the LCD segment and where the values for n are LCD n=1 for static mode n=2 for 1:2 multiplex n=4 for 1:4 multiplex The RMS off-state voltage (V ) for the LCD is calculated with Equation4: off(RMS) a2–2a+n VoffRMS = VLCD ----------------------------2-- (4) n1+a Discrimination is the ratio of V to V and is determined from Equation5: on(RMS) off(RMS) D = -V----o---n----R---M----S---- = a----2---+-----2----a----+-----n-- (5) V 2 offRMS a –2a+n It should be noted that V is sometimes referred as the LCD operating voltage. LCD 8.4.5.1 Electro-optical performance Suitable values for V and V are dependent on the LCD liquid used. The on(RMS) off(RMS) RMS voltage, at which a pixel will be switched on or off, determine the transmissibility of the pixel. For any given liquid, there are two threshold values defined. One point is at 10% relative transmission (at V ) and the other at 90% relative transmission (at V ), see th(off) th(on) Figure23. For a good contrast performance, the following rules should be followed: V V (6) onRMS thon V V (7) offRMS thoff V and V are properties of the display driver and are affected by the selection on(RMS) off(RMS) of a (see Equation3), n (see Equation4), and the V voltage.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 8.5 Backplane and segment outputs 8.5.1 Backplane outputs The LCD drive section includes four backplane outputs: BP0 to BP3. The backplane output signals are generated based on the selected LCD multiplex drive mode. Table30 describes which outputs are active for each of the multiplex drive modes and what signal is generated. Table 30. Mapping of output pins and corresponding signals with respect to driving mode MUX mode Output pin BP0 BP1 BP2 BP3 Signal 1:4 BP0 BP1 BP2 BP3 1:2 BP0 BP1 BP0[1] BP1[1] static BP0 BP0[1] BP0[1] BP0[1] [1] These pins may optionally or alternatively be connected to the display to improve drive strength. Connect only with the corresponding output pin carrying the same signal. If not required, they can be left open circuit. 8.5.1.1 1:4 multiplex drive mode In the 1:4 multiplex drive mode, BP0 to BP3 must be connected directly to the LCD. 8.5.1.2 1:2 multiplex drive mode In the 1:2 multiplex drive mode, BP0 and BP1 must be connected directly to the LCD. The unused BPs may be left open-circuit. Optionally they may also be connected to the display to increase drive strength. • BP0 is repeated on BP2 • BP1 is repeated on BP3 8.5.1.3 Static drive mode In the static drive mode, BP0 must be connected directly to the LCD. In the static drive mode, the same signal is carried by all four backplane outputs and they can be connected in parallel for very high drive requirements. • BP0 is repeated on BP1, BP2, and BP3 8.5.2 Segment outputs The LCD drive section includes up to 44segment outputs. The segment output signals are generated based on the multiplexed backplane signals and with data resident in the display register. When less than 44segment outputs are required, the unused segment outputs must be left open-circuit.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 8.6 Display controller The display controller executes the commands identified by the command decoder. It contains the status registers of the PCA8547 and co-ordinates their effects. The controller is also responsible for loading display data into the display RAM as required by the filling order. 8.7 Display register The display register holds the display data while the corresponding multiplex signals are generated. 8.8 Display RAM The display RAM stores LCD data. Depending on the multiplex drive mode, the arrangement of the RAM is changed. • multiplex drive mode 1:4: RAM is 44  4bit arranged in two banks • multiplex drive mode 1:2: RAM is 44  2bit arranged in two banks • static drive mode: RAM is 44  1bit arranged in two banks A logic1 in the RAM bit map indicates the on-state of the corresponding LCD element; similarly, a logic0 indicates the off-state. There is a one-to-one correspondence between • the bits in the RAM bitmap and the LCD elements, • the RAM columns and the segment outputs, • the RAM rows and the backplane outputs.

Fig 28. Display RAM bitmap The display RAM bit map, Figure28, shows row0 to row7 which correspond with the backplane outputs BP0 to BP3, and column0 to column43 which correspond with the segment outputs S0 to S43. The number of rows is twice the number of backplane outputs allowing to use two different RAM banks (see Section8.9). When display data is transmitted to the PCA8547, the display bytes received are stored in the display RAM in accordance with the selected LCD multiplex drive mode. The data is stored as it arrives. Depending on the current multiplex drive mode, data is stored singularly, in pairs, or quadruples. 8.8.1 Data pointer The addressing mechanism for the display RAM is realized using the data pointer. This allows the loading of an individual display data byte, or a series of display data bytes, into any location of the display RAM. The sequence commences with the initialization of the data pointer by the Load-data-pointer command (see Table16 on page13). Following this command, an arriving data byte is stored starting at the display RAM address indicated by the data pointer.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump After each byte stored, the data pointer is automatically incremented in accordance with the chosen LCD multiplex drive mode configuration: • by eight (static drive mode) • by four (1:2 multiplex drive mode) • by two (1:4 multiplex drive mode) When the address counter reaches the end of the RAM row, it stops incrementing after the last byte is transmitted. Redundant bits of the last byte transmitted are discarded. Additional bytes, sent after the end of the RAM is reached, will be discarded too. The data pointer does not wrap around to the beginning. To send new RAM data, the data pointer must be reset. If an I2C-bus or SPI-bus data access is terminated early, then the state of the data pointer is unknown. The data pointer must then be re-written before further RAM accesses. 8.8.2 RAM filling in static drive mode In the static drive mode the eight transmitted data bits are placed in eight successive display RAM columns in row0 (see Figure29).

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 8.9 Bank selection The PCA8547 includes a RAM bank switching feature. A bank can be thought of as a collection of RAM rows. The RAM bank switching gives the provision for preparing display information in an alternative bank and to be able to switch to it once it is complete. There are two banks; bank0 and bank1. Figure28 on page40 shows the location of these banks relative to the RAM map. Input and output banks can be set independently from one another with the Bank-select command (see Table19 on page15). Figure33 shows the concept.

Bus interfaces 9.1 Control byte After initiating the communication over the bus and sending the slave address (I2C-bus, see Section9.2) or subaddress (SPI-bus, see Section9.3), a control byte follows. The purpose of this byte is to indicate both, the content for the following data bytes (RAM or command) and to indicate that more control bytes will follow. Typical sequences could be: • Slave address/subaddress - control byte - command byte - command byte - command byte - end • Slave address/subaddress - control byte - RAM byte - RAM byte - RAM byte - end • Slave address/subaddress - control byte - command byte - control byte - RAM byte - end In this way, it is possible to send a mixture of RAM and command data in one access or alternatively, to send just one type of data in one access.

Control byte format 9.2 I2C-bus interface characteristics (PCA8547A) The I2C-bus is for bidirectional,two-line communication between different ICs or modules. The two lines are a Serial DAta line (SDA) and a Serial CLock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy. 9.2.1 Bit transfer One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as a control signal (see Figure36).

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump • A slave receiver which is addressed must generate an acknowledge after the reception of each byte. • Also a master receiver must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. • The device that acknowledges must pull-down the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse (set-up and hold times must be considered). • A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a STOP condition. Acknowledgement on the I2C-bus is shown in Figure39.

Acknowledgement on the I2C-bus 9.2.5 I2C-bus controller The PCA8547A acts as an I2C-bus slave receiver. It does not initiate I2C-bus transfers or transmit data to an I2C-bus master receiver. The only data output from PCA8547A are the acknowledge signals and the temperature readout byte of the selected device. 9.2.6 Input filters To enhance noise immunity in electrically adverse environments, RC low-pass filters are provided on the SDA and SCL lines. 9.2.7 I2C-bus slave address The device selection depends on the I2C-bus slave address. Two different I2C-bus slave addresses can be used to address the PCA8547A (see Table32).

Therefore, two instances of PCA8547A can be distinguished on the same DD I2C-bus. The least significant bit of the slave address byte is bit R/W (see Table33). Table 33.

The sequence is initiated with a START condition (S) from the I2C-bus master which is followed by one of the two PCA8547A slave addresses available. All PCA8547A’s with the corresponding A0 level acknowledge in parallel to the slave address, but all PCA8547A with an alternative A0 level ignore the whole I2C-bus transfer.

After the last display byte, the I2C-bus master issues a STOP condition(P). Alternatively a START may be issued to RESTART an I2C-bus access. 9.2.9 Data read If a temperature readout (byte TD[7:0]) is made, the R/W bit must be logic1 and then the next data byte following is provided by the PCA8547A as shown in Figure41.

I2C-bus protocol, read mode 9.3 SPI-bus interface (PCA8547B) Data transfer to the device is made via a three-line SPI-bus (see Table31). The SPI-bus is reset whenever the chip enable pin CE is inactive. Table 34. Serial interface Pin Function Description CE chip enable input; active LOW[1] when HIGH, the interface is reset; SCL serial clock input - SDIO serial data input output input data is sampled on the rising edge of SCL; data is output on the falling edge of SCL [1] The chip enable must not be wired permanently LOW. 9.3.1 Data transmission The chip enable signal is used to identify the transmitted data. Each data transfer is a byte, with the Most Significant Bit (MSB) sent first. The transmission is controlled by the active LOW chip enable signal CE. The first byte transmitted is the subaddress byte.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 9.3.2 Data read The temperature readout data byte TD[7:0] can be read from the PCA8547B. A readout is initiated by sending the subaddress byte with the R/W bit set high. The transmission is controlled by the active LOW chip enable signal CE. After the last bit of the subaddress byte is transmitted, the PCA8547B will immediately start to drive the SDIO line. It is only necessary to read the values once, however since the update of the register is asynchronous to the interface clock, it is recommended to read the register twice and check for a stable value. The readout is terminated by asserting CE. At this time, the SDIO bus is released. It is important that the bus is not left floating and that the microcontroller then takes over driving of the bus.

Such precautions are described in the ANSI/ESD S20.20, IEC/ST61340-5, JESD625-A or equivalent standards. CAUTION Static voltages across the liquid crystal display can build up when the LCD supply voltage (V ) is on while the IC supply voltage (V ) is off, or vice versa. This may cause unwanted LCD DD display artifacts. To avoid such artifacts, V and V must be applied or removed together.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 17. Handling information All input and output pins are protected against ElectroStatic Discharge (ESD) under normal handling. When handling Metal-Oxide Semiconductor (MOS) devices ensure that all normal precautions are taken as described in JESD625-A, IEC61340-5 or equivalent standards. 18. Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 18.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 18.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • Board specifications, including the board finish, solder masks and vias • Package footprints, including solder thieves and orientation • The moisture sensitivity level of the packages • Package placement • Inspection and repair • Lead-free soldering versus SnPb soldering PCA8547 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2015.

PCA8547 NXP Semiconductors 4 x 44 automotive LCD driver with integrated charge pump 18.3 Wave soldering Key characteristics in wave soldering are: • Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave • Solder bath specifications, including temperature and impurities 18.4 Reflow soldering Key characteristics in reflow soldering are: • Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure57) than a SnPb process, thus reducing the process window • Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board • Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table41 and42 Table 41. SnPb eutectic process (from J-STD-020D) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350  350 < 2.5 235 220  2.5 220 220 Table 42. Lead-free process (from J-STD-020D) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 to 2000 > 2000 < 1.6 260 260 260 1.6 to 2.5 260 250 245 > 2.5 250 245 245 Moisture sensitivity precautions, as indicated on the packing, must be respected at all times. Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure57.
