10 pcs : PCF8537AH/1,518 - LCD Drivers Industrial LCDdriver Rates up to 1:8

PCA8537 & PCF8537 LCD Drivers NXP Semiconductors PCA8537 and PCF8537 LCD Drivers are optimized for high-contrast Vertical Alignment (VA) LCD displays, with multiplex rates up to 1:8. The PCA8537 and PCF8537 generate the drive signals for any static or multiplexed LCD containing up to eight backplanes, 46 segments, and up to 352 elements. The PCA8537 and PCF8537 feature 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, these devices offer a programmable temperature compensation of the LCD supply voltage. The PCA8537 and PCF8537 can be easily connected to a microcontroller by either the two-line I2C-bus (PCA8537AH/PCF8537AH) or a three-line bidirectional SPI-bus (PCA8537BH/PCA8537BH).
