PCF8545  
Universal LCD driver for multiplex rates up to 1:8  
Rev. 1 — 13 November 2013  
Product data sheet  
1. General description  
The PCF8545 is a peripheral device which interfaces to almost any Liquid Crystal Display  
(LCD)1 with low multiplex rates. It generates the drive signals for any multiplexed LCD  
containing up to eight backplanes, and up to 320 elements. The PCF8545 is compatible  
with most microcontrollers and communicates via the two-line bidirectional I2C-bus  
(PCF8545A) or a three line unidirectional SPI-bus (PCF8545B). Communication  
overheads are minimized using a display RAM with auto-incremented addressing.  
For a selection of NXP LCD segment drivers, see Table 40 on page 61.  
2. Features and benefits  
Single-chip 320 elements LCD controller and driver  
Wide range for digital power supply: from 1.8 V to 5.5 V  
LCD supply range from 2.5 V up to 5.5 V  
LCD and logic supplies may be separated  
Low power consumption  
Selectable backplane drive configuration: 4, 6, or 8 backplane multiplexing  
Selectable display bias configuration  
320-bit RAM for display data storage  
400 kHz I2C-bus interface (PCF8545A)  
5 MHz SPI-bus interface (PCF8545B)  
Programmable frame frequency in the range of 60 Hz to 300 Hz in steps of 10 Hz;  
factory calibrated  
320 segments driven allowing:  
up to 40 7-segment alphanumeric characters  
up to 20 14-segment alphanumeric characters  
any graphics of up to 320 elements  
Manufactured in silicon gate CMOS process  
3. Applications  
Industrial and consumer products
