PCF8532U/2DA/1,026

Display Drivers Overview

The PCF8532U/2DA/1,026 is a universal LCD driver designed for low multiplex rates. It drives static or multiplexed LCDs with up to 4 backplanes and 160 segments. The device features an I²C interface, internal bias generation, and display RAM. It supports cascading for large displays and operates on a wide power supply range from 1.8 V to 5.5 V.

Display Drivers Feature Summary

• Generates drive signals for LCDs with up to four backplanes and 160 segments
• Communicates via dual-line bidirectional I²C bus compatible with most microcontrollers
• Includes display RAM with auto-increment addressing to reduce communication overhead
• Supports cascading for applications requiring up to 5120 elements

Display Drivers Applications

• Driving static or multiplexed LCD modules in industrial equipment
• Display interfaces for consumer electronics with low segment counts
• Large LCD applications utilizing cascaded driver configurations
• COG (Chip-on-Glass) module designs requiring integrated bias generation

Display Drivers Procurement Notes

Verify the specific suffix and tape/reel configuration when ordering. Confirm that the component meets the required environmental specifications for your application. Check current availability status as this part may be subject to lifecycle changes. Ensure compatibility with existing PCB footprints and design rules before procurement.

Display Drivers Selection Notes

Select this driver for applications requiring flexible LCD driving with minimal external components. It is suitable for systems needing independent logic and LCD power supplies. Consider the I²C interface requirements and address settings. Evaluate the need for cascading capabilities if the segment count exceeds 160.

Display Drivers Part Context

This component belongs to NXP's family of universal LCD drivers. It is designed to replace older discrete driver solutions by integrating control and drive functions into a single CMOS chip. The device simplifies design by eliminating the need for external bias generation circuits and reducing pin count through efficient multiplexing support.
