S6B0708

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 1 S6B0708 LCD 64COM/128SEG GRAPHIC DRIVER FOR DOT MATRIX BLOCK DIAGRAM C1 ...
