1. General description

2. Features

The PCF8566 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 24 segments and can easily be cascaded

for larger LCD applications. The PCF8566 is compatible with most microprocessors or

microcontrollers and communicates via a two-line bidirectional I

overheads are minimized by a display RAM with auto-incremented addressing, by

hardware subaddressing and by display memory switching (static and duplex drive

modes).
