PCF8566T/1,118

PCF8566T/1,118 is a universal LCD driver for low multiplex rates. It is a peripheral device that 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 24 segments and can easily be cascaded for larger LCD applications. The PCF8566 is compatible with most microprocessors or microcontrollers and communicates via a two-line bidirectional I2C bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware sub addressing and by display memory switching (static and duplex drive modes).

• No external components required (even in multiple device applications)
• Selectable backplane drive configuration: static or 2, 3, 4 backplane multiplexing
• Internal LCD bias generation with voltage-follower buffers, 24 × 4-bit RAM for display data storage
• Auto-incremented display data loading across device sub address boundaries
• Display memory bank switching in static and duplex drive modes, LCD and logic supplies may separated
• 2.5V to 6V power supply range, low power consumption
• Power-saving mode for extremely low power consumption in battery-operated and telephone applications
• TTL and CMOS compatible, manufactured in silicon gate CMOS process
• 40-leads plastic very small outline package
• Storage temperature range from -65 to +150°C
