PCF8576CHL/1,118

Overview

The PCF8576CHL/1,118 is a universal LCD driver designed for low multiplex rates. It interfaces with almost any Liquid Crystal Display (LCD) and generates drive signals for static or multiplexed displays containing up to four backplanes and 40 segments. The device communicates via a two-line bidirectional I²C-bus, minimizing communication overhead through display RAM with auto-incremented addressing and hardware subaddressing. It operates within a temperature range of -40 °C to 85 °C and is housed in a 64-pin LQFP package.

Feature Summary

• Single-chip LCD controller and driver supporting up to 40 segment drives
• Compatible with most microcontrollers via two-line bidirectional I²C-bus interface
• Generates drive signals for static or multiplexed LCDs with up to four backplanes
• Minimizes communication overhead using display RAM with auto-incremented addressing

Applications

• Low multiplex rate liquid crystal display systems
• Microcontroller-based peripheral display interfacing
• Cascaded larger LCD applications requiring multiple drivers

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's current product data sheet to ensure compatibility with design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Cross-reference the part number with official NXP documentation to validate availability and manufacturing status, as component specifications may evolve over time.

Selection Notes

Select this component for applications requiring a dedicated driver for low multiplex rate LCDs with up to 40 segments. Ensure the system architecture supports I²C communication and that the display configuration does not exceed the four-backplane limit. Consider cascading capabilities if the application requires driving larger displays beyond the single-chip capacity.

Part Context

This component belongs to the PCF8576 family of universal LCD drivers manufactured by NXP Semiconductors. It serves as a peripheral device specifically engineered to interface with liquid crystal displays. The series is characterized by its ability to handle segment drives efficiently while maintaining low power consumption and simplified communication protocols through standard bus interfaces.

Replacement Considerations

Consult the NXP LCD segment driver selector table for verified substitute part numbers. Ensure any replacement maintains compatibility with the required segment count, backplane configuration, and I²C interface specifications.
