1/2 Duty LCD Driver
with On-Chip Key Input Function
http://onsemi.com
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.
