2.85V Power supply

4

GND

P

Power ground

5

8B_4W

I

Select the MCU interface mode:

When 8b_4w='0', 8080 MCU 8-bit interface is selected.

When 8b_4w ='1', 4-wire 8-bit data serial interface is selected.

6

/RESET

I

Reset pin. Initializes the LCM when low.

7

/CS

I

Chip select input pin( "Low" enable). This pin can be permanently fixed "Low" in MPU interface mode only

8

/ RS_SCL

I

This pin is used to select "Data or Command" in the parallel interface:

When DCX='1', data is selected.

When DCX='0', command is selected.

This pin is used to be serial interface clock in 4-wire 8-bit serial data interface.

9

/WR_RS

I

8080 system (WRX): Serves as a write signal and writes data at the rising edge.

4-line system (D/CX): Serves as command or parameter select.

10

/RD

I

8080 system (RD): Serves as a read signal and MCU read data at the rising edge.

Fix to IOVCC level when not in using.

11

SDA

I/O

Serial input/ouput signal in 4-wire 8-bit serial data interface.

The data is applied on rising edge of the SCL signal.

If not used, fix this pin at VCC or GND

12~19

DB0~DB7

I

8-bit parallel bi-directional data bus for MCU system.

20

TE

O

Tearing effect output. If not used, please open this pin.
