PCF8566 - Universal LCD driver

General Description

The PCF8566 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 24 segments and can easily be cascaded for larger LCD applications.

Key Features

  • I Single-chip LCD controller/driver I 24 segment drives: N Up to twelve 7-segment numeric characters including decimal pointer N Up to six 14-segment alphanumeric characters N Any graphics of up to 96 elements I Versatile blinking modes I No external components required (even in multiple device.

PCF8566 Universal LCD driver for low multiplex rates Rev. 07 — 25 February 2009 Product data sheet 1. General description The PCF8566 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 24 segments and can easily be cascaded for larger LCD applications. The PCF8566 is compatible with most microprocessors or microcontrollers and communicates via a two-line bidirectional I2C-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.
