PCF8576CT/1,118

Overview

The PCF8576CT/1,118 is a universal LCD driver designed for low multiplex rates. It interfaces with microcontrollers via a two-line bidirectional I2C-bus. The device generates drive signals for static or multiplexed LCDs containing up to four backplanes and 40 segments. It features a single-chip LCD controller and driver architecture with selectable backplane configurations (static, 2, 3, or 4 backplanes). The component includes internal LCD bias generation with voltage-follower buffers and supports display memory bank switching in static and duplex drive modes.

Feature Summary

• Single-chip LCD controller and driver supporting up to 40 segment drives
• Two-line bidirectional I2C-bus interface compatible with most microprocessors
• Selectable backplane drive configuration for static or multiplexed displays
• Internal LCD bias generation with voltage-follower buffers

Applications

• Static or low-multiplex Liquid Crystal Displays
• Battery-operated telephone applications
