The PCA8547 is a fully featured Liquid Crystal Display (LCD) driver, specifically designedfor high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:4. It generatesthe drive signals for any static or multiplexed LCD containing up to four backplanes,44 segments, and up to 176 elements. The PCA8547 features an internal charge pumpwith internal capacitors for on-chip generation of the LCD driving voltage. To ensure anoptimal and stable contrast over the full temperature range, the PCA8547 offers aprogrammable temperature compensation of the LCD supply voltage. The PCA8547 canbe easily connected to a microcontroller by either the two-line I2C-bus (PCA8547A) or athree-line bidirectional SPI-bus (PCA8547B).\n
