Description

1

/CS1

This is the chip select signal. When /CS1 = “L” and CS2 = “H”, then the chip select becomes active, and data/command I/O is enabled.

2

/RES

RESET signal

3

A0

This is connect to the least significant bit of the normal MPU address bus, and it determines whether the data bits are data or command.

A0 = “H”: Indicates that D0 to D7 are display data.

A0 = “L”: Indicates that D0 to D7 are control data.

4

/WR

(R/W)

When connected to 8080 series MPU, this pin is treated as the “/WR” signal of the 8080 MPU and is LOW-active.

The signals on the data bus are latched at the rising edge of the /WR signal.

5

/RD

(E)

When connected to 8080 series MPU, this pin is treated as the “/RD” signal of the

8080 MPU and is LOW-active.

The data bus is in an output status when this signal is “L”.

6~13

DB0~DB7

This is an 8-bit bi-direction data bus.

When serial interface is selected (P/S=”L”)

DB7 : serial data input (SI);

DB6 : the serial clock input (SCL).

DB0 ~ DB5 should be connected to VDD or floating.

When the chip select is not active, DB0 to DB7 are set to high impedance.

14

VDD

Power supply for logic.

15

VSS

Ground (GND)

16

VOUT

Connect a capacitor between this terminal and VSS

17

CAP3-

Connect a capacitor between this terminal and the CAP1+ Terminal.

18

CAP1+

Connect a capacitor between this terminal and the CAP1- Terminal.

19

CAP1-

Connect a capacitor between this terminal and the CAP1+ Terminal.

20

CAP2-

Connect a capacitor between this terminal and the CAP2+ Terminal.

21

CAP2+

Connect a capacitor between this terminal and the CAP2- Terminal.

22~26

V4~V0

This is a multi-level power supply for LCD module.

V0 ≧V1 ≧V2 ≧V3 ≧V4 ≧VSS

27

C86

This is the MPU interface switch terminal

C86=”H”：6800 Series MPU interface

C86=”L”：8080 MPU interface

28

P/S

This pin configures the interface to be parallel mode or serial mode.

P/S = “H”: Parallel data input/output.

P/S = “L”: Serial data input.
