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.
