S6B33A2 PRELIMINARY VER 1.3 128 RGB SEGMENT & 129 COMMON DRIVER FOR 4,096 COLOR STN LCD
INTRODUCTION
S6B33A2 is a mid-display-size-compatible driver for liquid crystal dot matrix gray-scale graphic systems. With on-
chip RC oscillator circuit, the display-timing signal is generated without being sent from MPU. Also, it is capable of
using 8bit/16bit data bus alternatively and operating with 68/80-series MPU in asynchronous. Due to the internal bit-
map display RAM of 128 ×128 ×12-bit, S6B33A2 is capable of operating max. 128 RGB x 128 dot LCD panels in
low-power consumption. Being the segment RGB 3-output, one pixel is 12-bit data and S6B33A2 can display 4,096
color.
