Universal LCD Driver for Multiplex Rates Up to 1-8

PCF8545 End of Life

The PCF8545 is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD) with low multiplex rates. It generates the drive signals for any multiplexed LCD containing up to eight backplanes, and up to 320 elements. The PCF8545 is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus (PCF8545A) or a three line unidirectional SPI-bus (PCF8545B). Communication overheads are minimized using a display RAM with auto-incremented addressing.
