PCA8539 100 x 18 Chip-On-Glass automotive LCD dot matrix driver Rev. 2 12 September 2014 Product data sheet 1. General description 1 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 2 connected to a microcontroller by either the two-line I C-bus or a four-line bidirectional SPI-bus. For a selection of NXP LCD graphic drivers, see Table 50 on page 86. 2.
