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/microcontrollers and communicates via a two-line bidirectional
I
2
C-bus. Communication overheads are minimized by a display RAM with auto-incremental addressing, by hardware
subaddressing and by display memory switching (static and duplex drive modes).
