PCF8562

PCF8562 Universal LCD driver for low multiplex rates Rev. 8 — 27 September 2021 Product data sheet 1 General description The PCF8562 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 32 segments. The PCF8562 is compatible with most microcontrollers and communicates via the 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). 2 Features and benefits AEC-Q100 compliant (PCF8562TT/S400/2) for automotive applications Single chip LCD controller and driver Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing Selectable display bias configuration: static, 1⁄2, or 1⁄3 Internal LCD bias generation with voltage-follower buffers 32 segment drives: – Up to sixteen 7-segment numeric characters – Up to eight 14-segment alphanumeric characters – Any graphics of up to 128 elements 32 × 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 Independent supplies possible for LCD and logic voltages Wide power supply range: from 1.8 V to 5.5 V Wide logic LCD supply range: – Fro...
