SPECIFICATIONS

Função do pino de interface

Pin No. Símbolo Descrição
1 ESD ESD
2 SI2 SI2 selects the interface type: I2C serial interface or not
SI2 Selected Interface
"L" Serial 4-Line SPI Interface
"H" I2C Serial Interface
3 VG VG is the LCD driving voltage for segment circuits
4 XV0 XV0 is the LCD driving voltage for common circuits at positive frame.
5 V0 V0 is the LCD driving voltage for common circuits at negative frame.
6 VSS GROUND
7 VDD POWER
8 SDA D[1:3] must be connected together as SDA.
D[4:7]=(1,1,1,1): ID Pin. D[4:7] should fix to “H” or “L” by VDDH or
VSSL.
9 SCL
10 A0 It determines whether the access is related to data or command.
A0=“H” : Indicates that signals on D[7:0] are display data.
A0=“L” : Indicates that signals on D[7:0] are command.
11 RSTB Hardware reset input pin. When RSTB is “L”, internal initialization is executed and the internal registers will be initialized.
12 CSB Chip select input pin. Interface access is enabled when CSB is “L”.
When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance.
13 ESD ESD
