PCF8576CTT/1,118

Overview

The PCF8576CTT/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 display RAM with auto-incremented addressing to minimize communication overhead. The component operates within a temperature range of -40 °C to 85 °C and utilizes an SSOP-56 package.

Feature Summary

• Single-chip LCD controller and driver architecture
• Supports up to forty segment drives for various character formats
• Two-line bidirectional I2C-bus interface compatibility
• Display RAM with auto-incremented addressing capability

Applications

• Low multiplex rate liquid crystal displays
• Microcontroller peripheral interfacing
• Static or multiplexed LCD applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape-and-reel specifications. Confirm that the I2C address configuration matches the system design requirements. Check for any RoHS compliance declarations relevant to the manufacturing batch. Ensure the supply chain source provides valid traceability for the NXP Semiconductors product line.

Selection Notes

Select this component when designing systems requiring a dedicated driver for low multiplex rate LCDs with limited segment counts. It is suitable for applications where I2C bus connectivity is preferred over parallel interfaces. Consider the thermal operating range and package constraints during the layout phase. Evaluate the cascading capabilities if larger display areas are required beyond the single-chip limits.

Part Context

This part belongs to the PCF8576C family of universal LCD drivers manufactured by NXP Semiconductors. The family includes variants such as the PCF8576CHL and PCF8576CTT, which differ primarily in packaging and reel specifications. These devices are engineered to simplify the integration of segment-based displays into embedded systems by handling the complex drive signal generation internally.
