General description

The PCF8576C 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 40 segments and can easily

be cascaded for larger LCD applications. The PCF8576C 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-incremented addressing and by hardware subaddressing.
