The definition of the abbreviations and acronyms used in this data sheet can be found in

The PCF8576C is a peripheral device which interfaces to almost any Liquid Crystal

Display (LCD)

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

auto-incremented addressing and by hardware subaddressing.



C-bus. Communication overheads are minimized by a display RAM with

PCF8576C

Universal LCD driver for low multiplex rates
