PCF8531

34 x 128 pixel matrix driver

Rev. 7 — 12 December 2013

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

For a selection of NXP LCD graphic drivers, see Table 20 on page 48.

2. Features and benefits

 Single-chip LCD controller and driver

 34 row and 128 column outputs

 Generation of intermediate LCD bias voltages

 Power-On Reset (POR)

 No external components required

 Software selectable bias configuration

 Logic supply voltage range V_DD1to V_SS1: 1.8 V to 5.5 V

 Supply voltage range for on-chip voltage generator V_DD2and V_DD3to V_SS1and V_SS2

2.5 V to 4.5 V

 Display supply voltage range V_LCDto V_SS
