LC75852E: LCD Driver, 1/2 Duty, with Key Input

The LC75852E is 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.
