General description
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 I²C-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).
Features
Single-chip LCD controller/driver
Selectable backplane drive configuration: static or 2/3/4 backplane multiplexing
Selectable display bias configuration: static, ½ 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 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
Versatile blinking modes
LCD and logic supplies may be separated
Wide power supply range: from 2 V for low-threshold LCDs and up to 9 V for guest-host LCDs and high-threshold (automobile) twisted nematic LCDs
