PCA8530DUG: Automotive 102 x 4 Chip-On-Glass LCD segment driver

Overview

The PCA8530 is a fully featured Chip-On-Glass (COG) Liquid Crystal Display (LCD) driver, designed for high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:4. It generates the drive signals for a static or multiplexed LCD containing up to 4 backplane, 102 segment outputs, and up to 408 segments/elements. The PCA8530 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 PCA8530 offers a programmable temperature compensation of the LCD supply voltage. The PCA8530 can be easily controlled by a microcontroller through either the two-line I²C-bus or a four-line bidirectional SPI-bus.
