PCF8576C
Universal LCD driver for low multiplex rates
Rev. 09 — 9 July 2009
Product data sheet
1. General description
The PCF8576C 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 40 segments and can easily
be cascaded for larger LCD applications. The PCF8576C is compatible with most
microprocessors or microcontrollers and communicates via a two-line bidirectional
I
2
C-bus. Communication overheads are minimized by a display RAM with
auto-incremented addressing, by hardware subaddressing.
2. Features
I
Single-chip LCD controller and driver
I
40 segment drives:
N
Up to twenty 7-segment numeric characters
N
Up to ten 14-segment alphanumeric characters
N
Any graphics of up to 160 elements
I
Versatile blinking modes
I
No external components required (even in multiple device applications)
I
Selectable backplane drive configuration: static or 2, 3, 4 backplane multiplexing
I
Selectable display bias configuration: static,

×
4-bit RAM for display data storage
I
Auto-incremented display data loading across device subaddress boundaries
I
Display memory bank switching in static and duplex drive modes
I
Wide logic LCD supply range:
N
From 2 V for low-threshold LCDs
N
Up to 6 V for guest-host LCDs and high-threshold twisted nematic LCDs
I
Low power consumption
I
May be cascaded for large LCD applications (up to 2560 segments possible)
I
Cascadable with 24-segment LCD driver PCF8566
I
No external components
I
Compatible with chip-on-glass technology
I
Separate or combined LCD and logic supplies
I
Optimized pinning for plane wiring in both and multiple PCF8576C applications
I
Power-saving mode for extremely low power consumption in battery-operated and
telephone applications
