PCF8576EUG/2DA/1KP

Overview

The PCF8576E is a bare die Universal LCD driver designed for low multiplex rates, specifically optimized for Chip-on-Glass (COG) applications. It interfaces with segmented displays containing up to four backplanes and 40 segments. The device generates drive signals for static or multiplexed LCDs using an internal bias generation circuit with voltage-follower buffers. It communicates via a two-line bidirectional I2C-bus, minimizing communication overhead through display RAM with auto-incremented addressing and hardware subaddressing. The component supports selectable backplane configurations (static, 2, 3, or 4 backplanes) and display bias settings (static, 1/2, or 1/3).

Feature Summary

• Single-chip LCD controller and driver compatible with COG technology
• Supports up to four backplanes and 40 segment drivers without external components
• Integrated I2C-bus interface with auto-incremented addressing for minimized communication overhead
• Internal LCD bias generation with voltage-follower buffers

Applications

• Segmented 4 x 40 displays with in-cell touch technology
• Industrial small appliances and white goods
• Medical measuring equipment such as blood pressure meters

Procurement Notes

Verify the specific suffix 'EUG/2DA/1KP' against official NXP documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the bare die form factor aligns with your assembly capabilities for Chip-on-Glass integration. Cross-reference the ordering part number with current production status to avoid obsolete stock.

Selection Notes

Select this component when designing systems requiring a dedicated LCD driver for low-multiplex displays integrated directly onto glass substrates. It is suitable for applications needing separate logic and LCD power supplies and low power consumption modes. Consider the I2C interface compatibility with your microcontroller and the requirement for up to 40 segment outputs.

Part Context

The PCF8576 series serves as a universal driver for low multiplex rate LCDs. The 'E' variant denotes the bare die version intended for COG mounting, distinct from packaged versions like the PCF8576C. This family allows for cascading to support larger display areas while maintaining low communication overhead through efficient memory management and bus protocols.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify if other PCF8576 variants or newer NXP LCD drivers meet the specific COG and electrical requirements.
