符號

功能說明

N.C. (GND)

The supporting pins can reduce the influences from stresses on the function pins. These pins must be connected to external ground.

C2N

DC/DC voltage converter.
Connect a capacitor between CA1P and CA1N.
Connect a capacitor between CA2P and CA2N.

C2P

C1P

C1N

VBAT

Analog power for internal booster. If VDD=VABT

DGND

Digital ground. Connect to GND

VDD

Power supply pin for core logic operation.

IF0

These pins select interface operation mode.

IF2	IF1	IF0	MPU interface type
L	L	L	4-line serial interface
L	L	H	3-line serial interface
L	H	L	I2C serial interface
H	H	L	8-bit 8080 parallel interface
H	L	L	8-bit 6800 parallel interface

IF1

IF2

CSB

Chip select input pin.
CSB=“L”: This chip is selected and the MPU interface is active.
CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance).

RSTB

This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation.

It determines whether the access is related to data or command.
A0 = "H": Indicates that D[7:0] are display data;
A0 = "L": Indicates that D[7:0] are control data.
This pin is I2C slave address bit (SA0), when I2C interface is selected.

RWR

Read / Write execution control pin. (This pin is only used in parallel interface)

MPU	RWR	Description
6800-series	R/W	Read / Write control input pin R/W = "H' : read R/W = "L" :write
8080-series	/WR	Write enable input pin. The data are latched at the rising edge of th /WR signal.

This pin is not used in serial interfaces and should be connected to DGND.

ERD

Read / Write execution control pin. (This pin is only used in parallel interface)

MPU Type	ERD	Description
6800-series	ERD	Read / Write control input pin. R/W = "H": When E is "H", data bus is in output status. R/W = "L": The data are latched at the falling edge of the E signal.
8080-series	/RD	Read enable input pin. When /RD is "L", data bus is in output status.

This pin is not used in serial interfaces and should be connected to DGND.

D0~D7

When using 8-bit parallel interface: 8080 or 6800 mode 8 bit bi-directional data bus. Connect to the data bus of 8-bit microprocessor. When CSB is “H”, D[7:0] are high impedance. When using serial interface : 3-line SPI or 4-line SPI mode
D[2:1] : serial input/output data (SDA).
D[0] : serial input clock (SCL).
D1 to D2 must be connected together (SDA)
D[7:3] : fix to “L” by DGND. When using serial interface : I2C interface
D[2] : SDA_OUT, serial data and acknowledge output for the I2C interface.
