PCF8577CT/3,112

Overview

The PCF8577CT/3,112 is a liquid crystal display driver manufactured by NXP USA Inc., designed for segment-based LCD applications. It operates within a supply voltage range of 2.5V to 6V and supports an industrial operating temperature range from -40°C to 85°C. The device features a 40-BSOP (40-VSO) surface-mount package with 40 pins. It provides 32-segment drive capability and utilizes an I2C interface for communication with microcontrollers.

Feature Summary

Integrates I2C-bus interface for simplified connection to microcontrollers
Provides direct or duplex drive modes for LCD segments
Includes internal display RAM to minimize communication overhead
Supports automatic incrementing addressing for efficient data loading

Applications

Segmented LCD displays in consumer electronics
Industrial control panels requiring low-power display drivers
Instrumentation interfaces with simple alphanumeric output

Procurement Notes

Verify component authenticity through authorized distributors as the part status is End-of-Life. Confirm package integrity upon receipt, as the 40-BSOP form factor requires careful handling during inspection. Cross-reference ordering codes such as 568-11583-5-ND for accurate identification against legacy inventory records.

Selection Notes

Select this component for designs requiring a dedicated I2C-controlled LCD driver with 32-segment capacity. Ensure the system logic voltage aligns with the 2.5V to 6V operating range. Consider the discontinued status when planning long-term production runs, as alternative sourcing may be necessary for future manufacturing phases.

Part Context

This device belongs to the PCF8577 family of LCD drivers from NXP Semiconductors. It serves as a specialized interface between digital controllers and analog LCD panels, translating serial I2C commands into parallel segment drive signals. The CT suffix indicates the specific tape-and-reel packaging variant within the broader product line.
