1. General description
2. Features
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
with auto-incremental addressing, by hardware subaddressing and by display memory
switching (static and duplex drive modes).
