PCF8531

34 x 128 pixel matrix driver

Rev. 6 — 16 May 2011

Product data sheet

1. General description

The PCF8531 is a low-power CMOS¹LCD row and column driver, designed to drive dot

matrix graphic displays at multiplex rates of 1:17, 1:26, and 1:34. Furthermore, it can drive

up to 128 icons. All necessary functions for the display are provided in a single chip,

including on-chip generation of V_LCDand the LCD bias voltages, resulting in a minimum of

external components and low power consumption. The PCF8531 is compatible with most

microcontrollers and communicates via a two-line bidirectional I²C-bus. All inputs are

CMOS compatible.

Remark: The icon mode is used to reduce current consumption. When only icons are

displayed, a much lower operating voltage (V_LCD) can be used and the switching

frequency of the LCD outputs is reduced. In most applications it is possible to use V_DDas

V_LCD
