PCA8533U/2DD/2,026

Display Drivers Overview

The PCA8533U/2DD/2,026 is a bare die LCD driver manufactured by NXP USA Inc. It interfaces with low multiplex rate liquid crystal displays, generating drive signals for static or multiplexed LCDs with up to four backplanes and eighty segments. The device communicates via a dual-line bidirectional I2C bus and includes display RAM with automatic increment addressing. It supports independent power supplies for logic and LCD voltages, ranging from 1.8 V to 5.5 V for logic and 2.5 V to 6.5 V for LCD. The component is designed for COG technology and can be cascaded for larger applications.

Display Drivers Procurement Notes

Verify the specific ordering suffix and revision level against the official NXP datasheet to ensure compatibility with your system requirements. Confirm that the bare die format meets your assembly capabilities, as this component requires specialized handling compared to packaged ICs. Check for end-of-life status or alternative recommendations from the manufacturer before finalizing procurement plans.

Display Drivers Selection Notes

Select this component when designing systems requiring direct control of low multiplex rate LCDs with minimal external circuitry. Ensure the design supports the required I2C communication protocol and provides separate power rails for logic and LCD drivers. Consider the bare die package constraints and verify that the target application environment accommodates the specified voltage ranges and temperature specifications.

Display Drivers Part Context

This part belongs to the PCA8533 family of LCD controllers and drivers from NXP Semiconductors. It is specifically identified as a bare die variant, intended for integration into custom modules or COG assemblies rather than standard PCB mounting. The device serves as a peripheral interface between microcontrollers and LCD panels, simplifying the drive circuitry for segment-based displays.

Display Drivers Replacement Considerations

Public sources indicate this product is no longer manufactured. Consult NXP documentation for recommended replacement parts or updated series within the LCD driver portfolio. Verify functional equivalence regarding segment count, backplane support, and interface protocols if selecting an alternative component.
