PCF85133U/2DA/1Z

Display Drivers Overview

The PCF85133U/2DA/1Z is a universal LCD driver for low multiplex rates, connecting to nearly any static or multiplexed LCD with up to 4 backplanes and 80 segments. It features an I²C interface, 80x4-bit display RAM, and supports frame frequencies of 82 Hz or 110 Hz. The device operates on a wide supply voltage range of 1.8 V to 5.5 V, with separate logic and LCD power supplies. It includes internal bias generation, automatic address incrementing, and cascading capabilities for large displays.

Display Drivers Feature Summary

• Generates drive signals for static or multiplexed LCDs with up to 4 backplanes and 80 segments
• Communicates via dual-line bidirectional I²C bus with automatic address incrementing
• Features internal LCD bias voltage generation using a voltage follower buffer
• Supports cascading for large-scale LCD applications

Display Drivers Applications

• Static or multiplexed LCD modules
• Large-size LCD applications requiring cascaded drivers
• Microcontroller-based systems requiring low communication overhead

Display Drivers Procurement Notes

Verify the specific suffix '2DA/1Z' against official NXP documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the ordering code matches the required bare die or packaged configuration for your manufacturing process.

Display Drivers Selection Notes

Select this component when driving LCDs with up to 80 segments and 4 backplanes. It is suitable for designs requiring I²C connectivity and low power consumption. Consider cascading if segment counts exceed 80. Verify compatibility with the target microcontroller's I²C speed and voltage levels.

Display Drivers Part Context

The PCF85133 is part of NXP's family of universal LCD drivers designed for low multiplex rates. It offers flexibility in backplane configurations and display bias settings. The device is manufactured using silicon gate CMOS technology and is compatible with COG (Chip On Glass) techniques.

Display Drivers Replacement Considerations

PCF8532U/2DA/1 is noted as a replacement for PCF8532, but direct substitution for PCF85133 requires verifying segment count differences (80 vs 160). Check datasheets for pinout and functional compatibility before replacing.
