PCF8537 Industrial LCD driver for multiplex rates up to 1:8
The PCF8537 is a fully featured Liquid Crystal Display (LCD) driver, specifically designed for high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:8. It generates the drive signals for any static or multiplexed LCD containing up to eight backplanes, 46 segments, and up to 352 elements. The PCF8537 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 PCF8537 offers a programmable temperature compensation of the LCD supply voltage. The PCF8537 can be easily connected to a microcontroller by either the two-line I²C-bus (PCF8537AH) or a three-line bidirectional SPI-bus (PCF8537BH
