DESCRIPTION

The PCF8533 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 80 segments and can easily be cascaded for larger LCD
applications. The PCF8533 is compatible with most
microprocessors/microcontrollers and communicates via a
two-line bidirectional I
are minimized by a display RAM with auto-incremented
addressing, by hardware subaddressing and by display
memory switching (static and duplex drive modes).
