9.0 INTERFACE
1 CS1B I
Data / instruction I/O is enabled only when CS1B is "L", When chip select is non-active, DB0 to DB7 may be high impedance.
2 RSTB I Reset input pin
When RSTB is "L", initialization is executed.
3 RS I
RS = "H": DB0 to DB7 are display data RS = "L": DB0 to DB7 are Instruction
4 SCL
5 SDA
Serial interface selected (PS ="L"); DB6: serial input clock (SCLK) DB7: serial input data (SID) When chip select is not active, DB6 and DB7 may be high impedance.
6 VDD Supply Power supply
7 VSS Supply Ground
8 VOUT I/O Voltage converter input/output pin. 9 C1- O Capacitor 1 negative connection pin for voltage converter. 10 C1+ O Capacitor 1 positive connection pin for voltage converter. 11 C2+ O Capacitor 2 positive connection pin for voltage converter. 12 C2- O Capacitor 2 negative connection pin for voltage converter. 13 V1 14 V2 15 V3 16 V4 17 V0 I/O LCD driver supply voltages. The voltage determined by LCD pixel is impedance-converted by an operational amplifier for application. Voltages should have the following relationship: AZ DISPLAY, INC. . 8
