PCF85133 - Universal LCD driver

Datasheet Summary

Description

The PCF85133 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 static or multiplexed LCD containing up to four backplanes and up to 80 segments and can easily be cascaded for larger LCD applications.

Features

Single-chip LCD controller and driver.
Selectable backplane drive configuration: static or 2, 3, or 4 backplane multiplexing.
Selectable display bias configuration: static, 1⁄2, or 1⁄3.
Selectable frame frequency: 82 Hz or 110 Hz.
Internal LCD bias generation with voltage-follower buffers.
80 segment drives:.
Up to 40 7-segment numeric characters.
Up to 20 14-segment alphanumeric characters.
Any graphics of up to 320 elements.
80  4 bit RAM for.

PCF85133 Universal LCD driver for low multiplex rates Rev. 3 — 4 July 2014 Product data sheet 1. General description The PCF85133 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 static or multiplexed LCD containing up to four backplanes and up to 80 segments and can easily be cascaded for larger LCD applications. The PCF85133 is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus. Communication overheads are minimized by a display RAM with auto-incremental addressing, by hardware subaddressing and by display memory switching (static and duplex drive modes). For a selection of NXP LCD segment drivers, see Table 27 on page 45. 2.
