PCA8576C

Universal LCD driver for low multiplex rates

Rev. 1 — 22 July 2010

Product data sheet

1. General description

The PCA8576C 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 and can easily

be cascaded for larger LCD applications. The PCA8576C is compatible with most

microprocessors or microcontrollers and communicates via a two-line bidirectional

C-bus. Communication overheads are minimized by a display RAM with

auto-incremented addressing and by hardware subaddressing.

AEC-Q100 compliant for automotive applications.

2. Features and benefits

Single-chip LCD controller and driver

40 segment drives:

Up to twenty 7-segment alphanumeric characters

Up to ten 14-segment alphanumeric characters

Any graphics of up to 160 elements

Versatile blinking modes

No external components required (even in multiple device applications)

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

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

Wide logic LCD supply range:

From 2 V for low-threshold LCDs

Up to 6 V for guest-host LCDs and high-threshold twisted nematic LCDs

Low power consumption

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

No external components

Separate or combined LCD and logic supplies

Optimized pinning for plane wiring in both and multiple PCA8576C applications

Power-saving mode for extremely low power consumption in battery-operated and

telephone applications

The definition of the abbreviations and acronyms used in this data sheet can be found in

Section 16.
