PCA8543
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 patible with most microcontrollers and municates via the two-line bidirectional I2C-bus. munication 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.
For a selection of NXP LCD segment drivers, see Table 40 on page 59.
