The PCF8576CT/1 is an universal LCD Driver for low multiplex rates and it 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 40 segments and can easily be cascaded for larger LCD applications. The driver is compatible with most microprocessors or microcontrollers and communicates via a two-line bi-directional I2C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing and by hardware sub addressing.
