PCF8577CP/F3,112

Overview

The PCF8577CP/F3,112 is a liquid crystal display driver manufactured by NXP USA Inc., housed in a 40-pin PDIP plastic package. It supports up to 64 segments driven in duplex mode with a dot matrix display configuration. The device operates on a serial data input mode and accepts standard input characteristics. It functions within an industrial temperature range of -40 °C to +85 °C and complies with RoHS standards.

Feature Summary

• Supports driving up to 64 segments in duplex mode for high-contrast displays
• Utilizes a serial interface for efficient data communication with microcontrollers
• Integrates internal circuitry suitable for dot matrix LCD configurations

Applications

• Industrial control panels requiring segment-based status indicators
• Consumer electronics with alphanumeric or simple graphic displays
• Instrumentation equipment utilizing direct LCD interfacing

Procurement Notes

Verify the specific suffix F3,112 against current NXP documentation to confirm availability status and exact packaging details. Cross-reference the PDIP40 physical dimensions and pinout with the official datasheet to ensure mechanical compatibility with existing PCB footprints. Confirm that the serial interface requirements align with the host controller's capabilities before finalizing procurement.

Selection Notes

Select this component when a dedicated LCD driver is required for systems using serial communication protocols rather than parallel interfaces. It is appropriate for designs needing robust support for duplex drive modes to maximize contrast without excessive power consumption. Ensure the application environment falls within the specified industrial temperature range and voltage constraints defined in the technical specifications.

Part Context

This part belongs to the PCF8577 family of LCD drivers designed for straightforward integration into embedded systems. It serves as a specialized interface between microcontrollers and liquid crystal displays, handling the necessary timing and voltage generation internally. The PDIP40 package offers through-hole mounting options suitable for prototyping or applications where surface-mount technology is not preferred.

Replacement Considerations

PCF8577CT/3,112 is a documented alternative variant within the same product family, offering similar functional capabilities in a different surface-mount package.
