NXP Semiconductors PCA85262 Automotive 32x4 LCD Driver

NXP PCA85262 Automotive 32x4 LCD Driver is a peripheral device that 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 32 segments. It can be easily cascaded for larger LCD applications. The NXP PCA85262 is compatible with most microcontrollers and communicates via the two-line bidirectional 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).
