PCF8576CT/1,112

Overview

The PCF8576CT/1,112 is a universal LCD driver designed for low multiplex rates. It interfaces with static or multiplexed LCDs containing up to four backplanes and 40 segments. The device communicates via a two-line bidirectional I2C-bus and includes display RAM with auto-incremented addressing. It supports selectable backplane configurations (static, 2, 3, or 4) and display bias settings (static, 1/2, or 1/3). The chip features internal LCD bias generation with voltage-follower buffers and versatile blinking 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
• Internal LCD bias generation with voltage-follower buffers
• Display memory bank switching in static and duplex drive modes

Applications

• Static or multiplexed liquid crystal displays
• Battery-operated telephone applications
• Consumer electronic devices requiring low power consumption
• Automotive twisted nematic LCDs

Procurement Notes

Verify the specific suffix /1,112 against official NXP documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and end-of-life status directly with the manufacturer or authorized distributors before procurement planning.

Selection Notes

Select this component for applications requiring a single-chip solution for low multiplex rate LCDs. Ensure the design utilizes an I2C-compatible microcontroller. Verify that the required segment count does not exceed 40 and backplane requirements fit within the static or 2/3/4 multiplexing options supported by the hardware.

Part Context

The PCF8576 series serves as a peripheral device for interfacing with various LCD types. This specific variant belongs to the family of universal LCD drivers characterized by low power consumption and flexible driving configurations. It is distinct from higher-capacity models like the PCF8536 or PCA8546 which support larger segment counts and additional PWM generators.
