NXP Semiconductors PCA8536
The PCA8536 is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD)1 with low multiplex rates. It generates the drive signals for any multiplexed LCD containing up to eight backplanes, up to 44 segments, and up to 320 elements. The PCA8536 is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus (PCA8536AT) or a three line unidirectional SPI-bus (PCA8536BT).| Part No. | PCA8536 |
