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.
