PCF8551

Universal 36 × 4 LCD segment driver

Rev. 3.1 — 3 May 2021

Product data sheet

1 General description

PCF8551 is an ultra low-power LCD segment driver with 4 backplane- and 36 segment-

driver outputs, with either an I2C- (PCF8551A) or an SPI-bus (PCF8551B) interface.

It comprises an internal oscillator, bias generation, instruction decoding, and display

controller.

For a selection of NXP LCD segment drivers, see Table 23.
