Product details
Overview
PCF8536AT/1,118 from NXP Semiconductors is an I²C-interface universal LCD driver IC supporting up to 8 backplanes and 44 segments (320 total elements), integrated with a 6-channel PWM generator for LED backlight control. It operates from 1.8 V to 5.5 V logic supply and 2.5 V to 9.0 V LCD supply, features factory-calibrated 60–300 Hz programmable LCD frame frequency, and targets low-multiplex-rate character/graphic displays in white goods.
For engineers reviewing the PCF8536AT/1,118 datasheet, PCF8536AT/1,118 pinout, PCF8536AT/1,118 application, or PCF8536AT/1,118 equivalent, this device delivers verified segment drive capability, configurable bias/mux modes, I²C-bus timing compliance at 400 kHz, and PWM channel resolution of 128 steps per output - critical for display fidelity and flicker-free illumination in cost-sensitive consumer HMI designs.
Technical Context
The PCF8536AT/1,118 implements dual-domain timing: an internal 230 kHz oscillator (factory calibrated) or external clock (9.6 kHz or 230 kHz) feeds independent prescalers for LCD frame generation (60–300 Hz, ±10 Hz steps) and PWM frame generation (programmable via FP[3:0]). Its display RAM uses auto-incremented addressing to minimize MCU communication overhead.
Backplane configuration supports 4-, 6-, or 8-mux operation with selectable line/frame inversion; bias mode is configurable as 1/2, 1/3, or 1/4; and each of six GPO pins (S0/GP0–S5/GP5) can be independently assigned as LCD segment, static GPO, or 7-bit PWM output - enabling simultaneous display driving and RGB backlight control without external drivers.

FAQ
What is the maximum LCD segment count supported by the PCF8536AT/1,118?
The PCF8536AT/1,118 supports up to 44 segments and 8 backplanes, enabling a total of 320 display elements. This allows configurations such as 40×7-segment alphanumeric characters, 20×14-segment layouts, or custom graphics matrices - all within a single TSSOP56 package. The 320-bit display RAM stores full frame data with auto-increment addressing.
Does the PCF8536AT/1,118 require an external crystal or oscillator?
No, the PCF8536AT/1,118 includes a factory-calibrated internal 230 kHz oscillator and does not require an external crystal. The OSCCLK pin can serve as either an output for the internal clock or an input for external 9.6 kHz or 230 kHz signals. External clocking is optional and used only when system-level synchronization or higher accuracy is needed beyond factory calibration.
How many independent PWM channels does the PCF8536AT/1,118 provide?
The PCF8536AT/1,118 provides six independent PWM channels (S0/GP0 through S5/GP5), each with 7-bit resolution (128 intensity levels). These channels support RGB backlight control with over 2 million color combinations, static GPO mode, or mixed LCD/PWM assignments - all configurable via the GPO-output-config command without external components.
What is the function of the A0 pin on the PCF8536AT/1,118?
The A0 pin on the PCF8536AT/1,118 selects the LSB of the I²C slave address, allowing two devices to share the same bus: A0 = low sets address 0x70, and A0 = high sets address 0x71. This enables multi-display systems (e.g., main panel + sub-display) without address conflicts, using standard 7-bit I²C protocol at up to 400 kHz.
Can the PCF8536AT/1,118 drive high-threshold LCDs?
Yes, the PCF8536AT/1,118 supports LCD supply voltages from 2.5 V to 9.0 V via the VLCD pin, making it compatible with both low-threshold STN and high-threshold twisted nematic (TN) LCDs. Its programmable bias modes (1/2, 1/3, 1/4) and multiplex configurations (1:4 to 1:8) allow electrical optimization for diverse panel types without external bias resistors.
