26 COM / 80 SEG DRIVER & CONTROLLER FOR STN LCD
KS0093
INTRODUCTION
The KS0093 is an LCD driver and controller LSI for liquid crystal dot matrix character display systems. It can
display 2 or 3 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
Table 3. Pin Description (Continued)
Description
Reset input
KS0093 is initialized while RESETB is low.
Chip selection input
KS0093 is selected while CSB is low.
Register selection input
When RS = "Low", instruction register
When RS = "High", data register.
In 80-series MPU interface mode
This pin is connected to WR pin of MPU and is a active low write signal
In 68-series MPU interface mode
This pin is connected to R/W pin of MPU
When RW_WR = "Low", write mode
When RW_WR = "High", read mode
In 80-series MPU interface mode
This pin is connected to RD pin of MPU and is a active low read signal
In 68-series MPU interface mode
This pin is connected to E pin of MPU and enable read or write command
according to RW_WR signal.
