PCA85176H/Q900/1,5

Display Drivers Overview

The PCA85176H/Q900/1,5 is an AEC-Q100 compliant single-chip LCD controller and driver designed for automotive applications. It supports selectable backplane multiplexing (static, 2, 3, or 4) and display bias configurations (static, 1/2, or 1/3). The device features 40 segment drives capable of supporting up to 20 7-segment numeric characters, 10 14-segment alphanumeric characters, or graphics with up to 160 segments/elements. It includes 40 x 4-bit RAM for display data storage and versatile blinking modes. Operating from a wide power supply range of 1.8 V to 5.5 V, it utilizes a 400 kHz I2C-bus interface and functions within an extended temperature range up to 95 °C.

Display Drivers Procurement Notes

Verify the specific suffix 'H' against official NXP documentation to confirm exact electrical characteristics and package variations compared to other variants in the PCA85176 family. Ensure compatibility with target I2C bus speeds and voltage levels. Confirm RoHS status and automotive qualification requirements match project specifications before finalizing procurement.

Display Drivers Selection Notes

Select this component when designing systems requiring robust automotive-grade LCD driving capabilities with flexible multiplexing options. It is suitable for applications needing high integration of controller and driver functions. Consider its wide operating voltage range and low power consumption for battery-sensitive automotive environments. Evaluate the 40-segment drive capacity against display complexity requirements.

Display Drivers Part Context

This part belongs to NXP's PCA851xx series of LCD drivers, which are optimized for automotive use. These devices integrate controller and driver functions to simplify system design. The series supports various display types including numeric, alphanumeric, and graphic segments. They are designed to meet stringent automotive quality standards while providing efficient power management for display subsystems.

Display Drivers Replacement Considerations

Check NXP datasheets for direct pin-to-pin compatible alternatives within the PCA851xx family. Verify if functional equivalents from other manufacturers support identical AEC-Q100 ratings and I2C interfaces. Ensure any substitute matches the required segment count and multiplexing configurations.
