Pin no.
Symbol
Function
1
CS
Chip select input pins
Data / instruction I/O is enabled only when CS1B is “L” and CS2 is “H”. when chip select is non-active, DB0 to DB7 may be high
impedance.
2
RESET
Reset input pin When /RES is “L”, initialization is executed.
3
A0
This is connected to the least significant bit of the normal MPU
address bus, and it determines whether the data bits are data
or a command.
A0 = “H”: Indicate that D0 to D7 are display data
A0 = “L”: Indicates that D0 to D7 are control data
4
SCL
Serial clock input pin.
5
SDA
Serial data input pin.
6
VDD
Power supply, +3.3V.
7
VSS
Power supply, 0V.
8
V0
LCD driver supplies voltages. It is generated by internal DC/DC
converter.
Connect a 0.1uF ~ 2.2uF capacitor between this pin and VSS
