64COM/128SEG GRAPHIC DRIVER FOR DOT MATRIX LCD
S6B0708
INTRODUCTION
S6B0708 is a single-chip LCD driver IC for liquid crystal dot-matrix graphic display systems. It incorporates 192
driver circuit for 64 common and 128 segment and 64 x 128-bit bit-map RAM. It is capable of interfacing with the
microprocessor, accepting 8-bit parallel display data directly from it, and storing data in an one chip display data
RAM. And it generates internal signals for using LCD driving independent of microprocessor clock.
FEATURES
• 64-channel common & 128-channel segment driver for dot matrix LCD
• On-chip display data RAM: 64 × 128 = 8192bits
• Display data is stored in display data RAM from MPU
- RAM bit data: ON(1), OFF(0)
• Internal timing generator circuit for dynamic display
• 8-bit parallel bi-directional data bus
• Applicable LCD duty: 1/64
• Power supply voltages: Power supply voltage range: 4.5 - 5.5V (VDD)
• LCD driving voltage range: 8.0 - 17.0V (VLCD = VDD-VEE)
• Wide operating temperature range: Ta = -30°C - 85°C
• High voltage CMOS process
• Gold bumped chip available
