OM4085 - Universal LCD driver for low multiplex rates

Datasheet Summary

Description

The OM4085 is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD) having low multiplex rates.

Features

  • Single-chip LCD controller/driver.
  • Selectable backplane drive configuration: static or 2, 3 or 4 backplane multiplexing.
  • Selectable display bias configuration: static, 1⁄2 or 1⁄3.
  • Internal LCD bias generation with voltage-follower buffers.
  • 24 segment drives: up to twelve 8-segment numeric characters; up to six 15-segment alphanumeric characters; or any graphics of up to 96 elements.
  • 24 × 4-bit RAM for display data storage.
  • Auto-incr.
