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

Display (LCD)¹with 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

microcontrollers and communicates via the two-line bidirectional I²C-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

 Selectable display bias configuration: static, ¹⁄₂, or ¹⁄₃

 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
