The PCF8534A is a peripheral device which interfaces to almost any Liquid Crystal
Display (LCD)
1
with low multiplex rates. It generates the drive signals for any static or
multiplexed LCD containing up to four backplanes and up to 60 segments. It can be easily
cascaded for larger LCD applications. The PCF8534A is compatible with most
microcontrollers and communicates via the two-line bidirectional I

C-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).
