PCF8536BT/1Y

Display Drivers Overview

The PCF8536BT/1Y is a universal LCD driver for low multiplex rates, featuring an integrated six-channel PWM generator. It drives up to eight backplanes, 44 segments, and 320 elements. The device uses a three-wire unidirectional SPI bus interface. It supports digital supply voltages from 1.8 V to 5.5 V and LCD supply voltages from 2.5 V to 9.0 V. The component operates within a temperature range of -40°C to 85°C and is housed in a TSSOP56 package.

Display Drivers Feature Summary

• Generates drive signals for low multiplex rate LCDs with up to 320 elements
• Includes a six-channel PWM controller for LED backlight illumination
• Communicates via a three-wire unidirectional SPI bus interface
• Features on-chip RAM for display data storage with automatic increment addressing

Display Drivers Applications

• White goods displays
• Consumer product interfaces
• Industrial equipment panels

Display Drivers Procurement Notes

Verify the specific suffix /1Y against current NXP documentation to confirm material declaration and environmental compliance status. Confirm that the component remains suitable for design-in despite its End of Life status by checking for available stock or approved alternative sources. Ensure the SPI interface requirement aligns with the BT variant designation.

Display Drivers Selection Notes

Select this part when a microcontroller requires a dedicated LCD driver with integrated LED backlight control via SPI. It is appropriate for designs needing high segment counts without external logic. Verify that the system voltage levels match the 1.8 V to 5.5 V digital supply range and that the thermal environment stays within the industrial operating limits.

Display Drivers Part Context

This component belongs to the PCF8536 family of universal LCD drivers manufactured by NXP Semiconductors. It serves as the industrial-grade counterpart to the automotive-certified PCA8536 series. The BT suffix indicates the presence of the SPI interface, distinguishing it from the AT variant which utilizes an I²C bus. The device simplifies system design by integrating both display driving and PWM generation capabilities.
