FEATURES Single-chip LCD controller & driver Driver Output Circuits l l l l l l l 132 segments / 39 mons (DTY=”L”) 132 segments / 12 mons (DTY=”H”) Capacity: 132X39=5148 bits 8-bit parallel bi-directional interface with 6800-series or 8080-series 4-line SPI (serial peripheral interface) available (only write operation) 3-line SPI (serial peripheral interface) available Embedded Boosters with voltage regulation function that generates high-accuracy voltage (externally V0I / XV0I voltage supply is also supported). On-chip Low Power Analog Circuit l l l l Voltage regulation temperature gradient -0.07%/°C Programmable Booster stages: X3,X4. On-chip electronic contrast control function Built-in Voltage Follower generates LCD bias voltages (1/4 to 1/7). Built-in oscillator l Built-in oscillator requires no external ponents (external clock input is also supported) External RESB (reset) pin Supply voltage range l l VDD - VSS (Digital): 2.4 to 3.3V (typical); VDD2 - VSS (Analog): 2.4 to 3.3V (typical). On-chip Display Data RAM (DDRAM) Microprocessor Interface Display supply voltage (V0-VSS) range: 3.0V~8.31V Temperature range: -30 to +85 degree Support LCD Module Size up to 1.4” 6800 , 8080 , 4-Line , 3-Line interface Ver 1.0a 1/48 2008/02/14 3.

Pitch 34 69 130 83 For easy LCM design, the Power-1, Power-2 & Power-3 are identical (any one of them can be used). Power-3 has VGI, VGS, V0O, V0I, V0S, XV0O, XV0I and XV0S which are not in Power-1 or Power-2. I/O Port-A and I/O Port-B are identical (except “RESB” pin). “MODE” pin is used to select Port-A or Port-B. Please note the unused pins...
