Chip on Glass LCD Module 240x128 with PCB - WO240128B2

사양

인터페이스 핀 기능

Pin No.

기호

기능

VDD

Power supply

No connection

VSS

Ground

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

Reset input pin. When RSTB is “L”, internal initialization procedure is executed

/RD(E)

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

MPU Type	ERD	Description
6800-series	E	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 out put status.

This pin is not used in serial interfaces and should be connected to VDD1

7~14

D7~D0

The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance
If using serial interface:
D0 is the SDA signal in 4-Line & 3-Line interface
D1 is the A0 signal in 4-Line interface

/WR/(R/W)

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

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

This pin is not used in serial interfaces and should be connected to VDD1

A0(SCL)

The function of this pin is different in parallel and serial interface
In parallel interface: A0 is register selection input
A0 = "H": inputs on data bus are display data
A0 = "L": inputs on data bus are command
In serial interface: this pad will be used as SCL (serial-clock) input
