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.
