PCA8543 4 x 60 automotive LCD segment driver with integrated charge pump Rev. 2 — 7 April 2015 Product data sheet 1. General description The PCA8543 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 static or multiplexed LCD containing up to four backplanes, 60 segments, and up to 240 elements. The PCA8543 is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus. Communication overheads are minimized using a display RAM with auto-incremented addressing and display memory switching. The PCA8543 features an internal charge pump with internal capacitors for on-chip generation of the LCD driving voltages.
