LC75852E, 75852W
Asynchronous Silicon Gate 1/2 Duty LCD Driver
with On-Chip Key Input Function
Overview
The LC75852E and LC75852W are 1/2 duty dynamic
LCD display drivers. In addition to being able to directly
drive LCD panels with up to 90 segments, they can also
control up to four general-purpose output ports. These
products also include a key scan circuit which allows
them to accept input from keypads with up to 30 keys.
This allows end product front panel wiring to be
simplified.
Features
• Up to 30 key inputs (Key scan is only performed when a
key is pressed.)
• 1/2 duty – 1/2 bias (up to 90 segments)
• Sleep mode and the all segments off function can be
controlled from serial data.
• Segment output port/general-purpose output port usage
can be controlled from serial data.
• Serial data I/O supports CCB format communication
with the system controller.
• High generality since display data is displayed directly
without decoder intervention
• Reset pin that can establish the initial state.

Control Data Functions
1. S0, S1 .................Sleep control data
This control data switches the LSI between normal mode and sleep mode. It also sets the key scan output standby
states for pins KS1 to KS6.
