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 I²C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware subaddressing.

1. The definition of the abbreviations and acronyms used in this data sheet can be found in Section 19.

Features

Single-chip LCD controller and driver
40 segment drives:
- Up to twenty 7-segment numeric 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 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 x 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)
Cascadable with 24-segment LCD driver PCF8566
No external components
Compatible with chip-on-glass technology
Separate or combined LCD and logic supplies
Optimized pinning for plane wiring in both and multiple PCF8576C applications
Power-saving mode for extremely low power consumption in battery-operated and telephone applications
