PCA8536BT/Q900/1,1

Display Drivers Overview

The PCA8536BT/Q900/1,1 is an automotive-grade LCD driver designed for low multiplex rates. It integrates a 320-segment LCD controller and a six-channel PWM generator for LED backlighting. The device operates on a digital supply voltage ranging from 1.8 V to 5.5 V and supports LCD voltages up to 9.0 V. Communication is handled via a three-wire SPI interface with a maximum clock frequency of 5 MHz. It features 320 bits of display RAM and supports up to eight backplanes. The component is housed in a TSSOP56 package and functions within a temperature range of -40 °C to +95 °C.

Display Drivers Feature Summary

• Integrates a single-chip 320-segment LCD controller and driver capable of supporting up to eight backplanes and 44 segments.
• Includes an on-chip six-channel PWM generator for LED illumination with 128-level resolution per channel.
• Utilizes a three-wire SPI serial interface for communication with microcontrollers.
• Features selectable display bias configurations and separate logic and LCD power supplies.

Display Drivers Applications

• Automotive dashboard displays
• Car radio interfaces
• Climate control panels

Display Drivers Procurement Notes

Verify the specific suffix Q900/1,1 against official NXP documentation to confirm the exact tape-and-reel packaging configuration and RoHS compliance status. Ensure the selected variant matches the required automotive qualification standards and operating temperature range for the intended application environment.

Display Drivers Selection Notes

Select this component when designing systems requiring high segment counts with integrated LED backlight control. The SPI interface reduces pin count compared to parallel alternatives. Verify that the target microcontroller supports the required SPI protocol and that the system voltage levels align with the specified 1.8 V to 5.5 V digital supply range.

Display Drivers Part Context

This part belongs to the PCA8536 family of universal LCD drivers manufactured by NXP Semiconductors. It is the automotive-qualified version of the PCF8536, distinguished by its extended operating temperature range and AEC-Q100 compliance. The BT suffix indicates the use of the SPI interface instead of the I²C bus found in the AT variants.

Display Drivers Replacement Considerations

The industrial equivalent PCF8536BT offers identical electrical functionality but lacks automotive qualification. Direct replacements must be verified against current NXP lifecycle notices as older revisions may be discontinued.
