INTRODUCTION
The S6A0094 is an LCD driver and controller LSI for liquid crystal dot matrix character display systems. It can display 2, 3 or 4 lines of 16 characters with 5 x 8 dots format. It is capable of interfacing various microprocessors, supporting the 4-bit, 8-bit parallel modes and the clock synchronized serial mode. Voltage converter, oscillator, voltage regulator, voltage follower and bias circuit are built in the IC. The double height character mode and line vertical scroll functions are supported.
