S6B33B2 is a mid-display-size-compatible driver for liquid crystal dot matrix gray-scale graphic systems. With on-chip CR 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 LCD driving signal (132 RGB X 162 output) corresponding to the display data and the internal bit-map display RAM of 132 ×163 ×16-bit, S6B33B2 is capable of operating max. 132 RGB x 162 dot LCD panels in low-power consumption. Being the segment RGB 3-output, one pixel is 16-bit data and S6B33B2 can max display 65,536 color.
