- PCA8539DUG
100 X 18 Chip-on-Glass Automotive LCD Dot Matrix Driver
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
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. 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 I²C-bus or a four-line bidirectional SPI-bus.
