PCF8534AH/1,518

Display Drivers Overview

The PCF8534AH/1,518 is an automotive-grade LCD driver manufactured by NXP Semiconductors. It interfaces with low multiplex rate displays via a two-line bidirectional I2C-bus operating at up to 400 kHz. The device supports static or multiplexed LCDs with up to four backplanes and 60 segments. It features selectable bias configurations (static, 1/2, or 1/3) and a wide logic supply range from 1.8 V to 5.5 V. Packaged in LQFP-80 for surface mount installation.

Display Drivers Feature Summary

• AEC-Q100 compliant single-chip LCD controller and driver
• Supports cascading for larger display applications
• Internal LCD bias generation with voltage follower buffers
• Display memory bank switching in static and duplex drive modes

Display Drivers Applications

• Automotive instrument clusters
• Low multiplex rate segment LCDs
• Graphics displays up to 240 elements

Display Drivers Procurement Notes

Verify the component status as discontinued or end-of-life through official NXP channels before design finalization. Confirm that the AEC-Q100 qualification meets specific project reliability requirements. Ensure the LQFP-80 package dimensions align with the target PCB layout constraints. Validate I2C bus compatibility with the host microcontroller.

Display Drivers Selection Notes

Select this component for applications requiring automotive-grade reliability and low power consumption. It is suitable for systems needing flexible backplane configurations and internal bias generation without external components. Consider cascading capabilities if the application requires driving more than 60 segments or four backplanes simultaneously.

Display Drivers Part Context

This part belongs to the PCF8534 family of universal LCD drivers designed for low multiplex rates. It serves as a peripheral device compatible with most microprocessors and microcontrollers. The AH suffix indicates compliance with the AEC-Q100 automotive qualification standard, distinguishing it from non-automotive variants within the same functional family.
