General description
The PCF8562 is a peripheral device which 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 32 segments. The PCF8562 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 subaddressing and by display memory switching (static and duplex drive modes).
AEC-Q100 compliant (PCF8562TT/S400) for automotive applications.
Features
- Single chip LCD controller and driver
- Selectable backplane drive configuration: static or 2, 3, 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 x 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:
- From 2.5 V for low-threshold LCDs
- Up to 6.5 V for guest-host LCDs and high-threshold twisted nematic LCDs
- Low power consumption
- 400 kHz I2C-bus interface
- No external components
- Manufactured in silicon gate CMOS process
