NXP PCx8536 LCD Drivers

NXP's PCx8536 LCD Drivers are a peripheral device which interfaces to almost any Liquid Crystal Display (LCD) with low multiplex rates. They generate the drive signals for any multiplexed LCD containing up to eight backplanes, up to 44 segments, and up to 320 elements. The PCx8536 is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus (PCx8536AT) or a three line unidirectional SPI-bus (PCx8536BT). Communication overheads are minimized using a display RAM with auto-incremented addressing. They feature an on-chip PWM controller for LED illumination. Up to six independent channels can be configured. Each channel has 128 levels allowing the possibility for two RGB controllers. Each of them provides over 2 million colors. Each channel can also be used for static drive.
