PCF85176

40 x 4 universal LCD driver for low multiplex rates

Rev. 3 — 5 September 2012

Product data sheet

1. General description

The PCF85176 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 40 segments. It can be easily

cascaded for larger LCD applications. The PCF85176 is compatible with most

microcontrollers and communicates via the two-line bidirectional I

C-bus. Communication

overheads are minimized by a display RAM with auto-incremented addressing, by

hardware subaddressing, and by display memory switching (static and duplex drive

modes).

2. Features and benefits



Single chip LCD controller and driver

Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing

Selectable display bias configuration: static,

⁄

, or

⁄

Internal LCD bias generation with voltage-follower buffers

40 segment drives:



Up to 20 7-segment numeric characters



Up to 10 14-segment alphanumeric characters



Any graphics of up to 160 elements



4-bit RAM for display data storage

Auto-incremented display data loading across device subaddress boundaries

Display memory bank switching in static and duplex drive modes

Versatile blinking modes

Independent supplies possible for LCD and logic voltages

Wide power supply range: from 1.8 V to 5.5 V

Wide logic LCD supply range:



From 2.5 V for low-threshold LCDs



Up to 6.5 V for guest-host LCDs and high-threshold twisted nematic LCDs

Low power consumption

400 kHz I

C-bus interface

May be cascaded for large LCD applications (up to 2560 elements possible)

No external components required

Manufactured in silicon gate CMOS process
