General description

The PCF8533 is a peripheral device which interfaces to almost any LCD1 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 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).
