PCF8576C Universal LCD driver for low multiplex rates Rev. 13 16 December 2013 Product data sheet 1. General description The PCF8576C is a peripheral device which interfaces to almost any Liquid Crystal 1 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 PCF8576C is compatible with most 2 microcontrollers and communicates via the two-line bidirectional I C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing and by hardware subaddressing. For a selection of NXP LCD segment drivers, see Table 24 on page 52. 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 1 1 Selectable display bias configuration: static, , or 2 3 Internal LCD bias generation with voltage-follower buffers 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 Wide logic LCD supply range: From 2 V for low-threshold LCDs Up to 6 V for high-threshold twisted nematic LCDs Low power consumption May be cascaded for large LCD applications (up to 2560 elements possible) No external components required Separate or combined LCD and logic supplies Optimized pinning for plane wiring in both single and multiple PCF8576C applications Power-saving mode for extremely low power consumption in battery-operated and telephone applications 1.
