---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
1 | VCI | Power supply pin for touch analog driving. VCI must be greater than or equal to VDD. | ||||||||||||||||||||
2 | VSS | Ground pin. | ||||||||||||||||||||
3 | VCC | Power Supply for Display. Most positive voltage. Connect to external source. | ||||||||||||||||||||
4 | VSL | This is segment voltage (output low level) reference pin. When external VSL is not used, connect externally to VSS. When external VSL is used, connect with resistor and diode to ground |
||||||||||||||||||||
5 | DCDCEN0 | Enable output pin for external DCDC circuit. NC if not used | ||||||||||||||||||||
6 | DCDCEN1 | Enable input pin for external DCDC circuit. Tie low if not used. | ||||||||||||||||||||
7 | VDD | Power supply pin for core logic operation. | ||||||||||||||||||||
8 | FR | This pin outputs RAM write synchronization signal. It should be kept NC if it is not used. |
||||||||||||||||||||
9 | DCS | This pin is the chip select input connecting to the MCU for display interface. | ||||||||||||||||||||
10 | TCS | This pin is the chip select input connecting to the MCU for touch. | ||||||||||||||||||||
11 | RES# | This pin is the reset signal input for display interface. | ||||||||||||||||||||
12 | TRES | This pin is the reset signal input for touch. | ||||||||||||||||||||
13 | DC | This pin is Data/Command control pin for display interface. In I2C mode, this pin acts as SA0 for slave address selection. |
||||||||||||||||||||
14 | E/RD# | In I2C mode, this pin acts as SA1 for slave address selection. | ||||||||||||||||||||
15 | IRQ | Interrupt signal for touch reporting. | ||||||||||||||||||||
16 | TD0 | Serial Data Input/Output and clock for Touch In SPI mode TD2 serves as SDOUT, TD1 serves as SDIN, and TD0 serves as the serial clock SCLK. In I2C mode TD2 and TD1 should be tied together and serve as SDA and TD0 is the serial clock SCL. External pull up resistors. |
