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)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  
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, 12, or 13  
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
