S6A0094
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.

Description
External clock input
It must be fixed to "High" or "Low" when the internal oscillation circuit is used.
In case of the external clock mode, CK is used as the clock and OS bit
should be OFF.
MPU interface selection input
MI = "Low": 80 series MPU
MI = "High": 68 series MPU
Parallel / Serial selection input
When PS = "Low": Serial mode
When PS = "High": 4-bit/8-bit bus mode
Interface data length selection pin for parallel data input
When PS = "Low"
IF = "Low" or "High": serial interface mode
When PS = “High”
IF = "Low": 4-bit bus mode
IF = "High": 8-bit bus mode
SEG direction selection input
When DIRS = "Low”
SEG1 → SEG2 → SEG79 → SEG80
When DIRS = "High”
SEG80 → SEG79 → SEG2 → SEG1
Display line mode selection input
