Universal LCD driver for low multiplex rates

Rev. 00.05 — 20 February 2007

Preliminary datasheet

1. General description

The PCF8534 is a peripheral device which interfaces to almost any Liquid Crystal Display

(LCD) with low multiplex rates. It generates the drive signals for any static or multiplexed

LCD containing up to four backplanes and up to 60 segments and can easily be cascaded

for larger LCD applications. The PCF8534 is compatible with most

microprocessors / microcontrollers and communicates via a two-line bidirectional I²C-bus.

Communication overheads are minimized using a display RAM with auto-incremented

addressing, hardware subaddressing and display memory switching (static and duplex

drive modes).

2. Features

Single-chip LCD controller / driver

Selectable backplane drive

configuration: static or 2 / 3 / 4

backplane multiplexing

Selectable display bias configuration:

static, ¹⁄₂or ¹⁄₃

Internal LCD bias generation with

voltage-follower buffers

60 segment drives: up to thirty

8-segment numeric characters; up to

sixteen 15-segment alphanumeric

characters; or any graphics of up to

240 elements

60 x 4-bit RAM for display data storage

Auto-incremented display data loading Display memory bank switching in static

across device subaddress boundaries

and duplex drive modes

Versatile blinking modes

LCD and logic supplies may be

separated

Wide power supply range: from

Wide LCD supply range: from 2.5 V for

low threshold LCDs and up to 6.5 V for

guest-host LCDs and high threshold

(automobile) twisted nematic LCDs

1.8 to 5.5 V

Low power consumption

TTL/CMOS compatible

400 kHz I²C-bus interface

Compatible with 4-bit, 8-bit or 16-bit

microprocessors/microcontrollers

May be cascaded for 2 LCD applications No external components
