The 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. It can be easily cascaded for larger LCD applications. The driver is compatible with most microcontrollers and communicates via the two-line bi-directional I²C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware sub addressing and by display memory switching static and duplex drive modes.
