FEATURES
? Single-chip LCD controller/driver
? Selectable backplane drive configuration: static or 2/3/4
backplane multiplexing
? Selectable display bias configuration: static, 1 ? 2 or 1 ? 3
? Internal LCD bias generation with voltage-follower
buffers
? 40 segment drives: up to twenty 8-segment numeric
characters; up to ten 15-segment alphanumeric
characters; or any graphics of up to 160 elements
? 40 × 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
? LCD and logic supplies may be separated
? May be cascaded for large LCD applications (up to
2560 segments possible)
? Cascadable with 24-segment LCD driver PCF8566
? Optimized pinning for plane wiring in both single and
multiple PCF8576 applications
? Space-saving 56-lead plastic very small outline package
(VSO56)
? Very low external component count (at most one
resistor, even in multiple device applications)
? Compatible with chip-on-glass technology
? Manufactured in silicon gate CMOS process.
? Wide power supply range: from 2 V for low-threshold
LCDs and up to 9 V for guest-host LCDs and
2
GENERAL DESCRIPTION
high-threshold (automobile) twisted nematic LCDs
? Low power consumption
? Power-saving mode for extremely low power
consumption in battery-operated and telephone
applications
? I 2 C-bus interface
? TTL/CMOS compatible
? Compatible with any 4-bit, 8-bit or 16-bit
microprocessors/microcontrollers
The PCF8576 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 PCF8576 is compatible with most
microprocessors/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 and by display
memory switching (static and duplex drive modes).
