PCA8547 Automotive 4x44 LCD Drivers NXP PCA8547 Automotive 4x44 LCD Drivers are specifically designed for high-contrast Vertical Alignment (VA) LCDs with multiplex rates up to 1:4. They generate the 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 pump with internal capacitors for on-chip generation of the LCD driving voltage. To ensure an optimal and stable contrast over the full temperature range, the PCA8547 offers a programmable temperature compensation of the LCD supply voltage. The NXP PCA8547 can be easily connected to a microcontroller by either the two-line I2C-bus (PCA8547A) or a three-line bi-directional SPI-bus (PCA8547B).
