NXP USA Inc. PCA8539DUG/DAZ

Description
The PCA8539 is a fully featured Liquid Crystal Display (LCD) driver, specifically designed for high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:18. It generates the drive signals for multiplexed LCD containing up to 18 backplanes, 100 segments, and up to 1800 elements/segments. The PCA8539 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 PCA8539 offers a programmable temperature compensation of the LCD supply voltage. The PCA8539 can be easily connected to a microcontroller by either the two-line 12C-bus or a four-line bidirectional SPI-bus.
