General description

The PCF8532 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 160 segments and can easily be

cascaded for larger LCD applications. The PCF8532 is compatible with most

microprocessors or microcontrollers and communicates via a two-line bidirectional

I2C-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).
