The CP2532/CP2528 is 12/8 channels capacitive touch panel controller, used for scroll, navigation and selection detection. The controller contains SPI or I2C serial interface, extendable GPIO, high PSRR LDO and in-built OSC. The touch status can be read via serial interface or GPIO. GPIO can be configured to open drain mode. Particularly, adjacent sensor suppression (ASS) function ensures only one channel active each time. The range of power is 2.6V ~ 5.5V. Low-power operation makes the CP2532/CP2528 ideal for battery-operated systems, such as multimedia portable product. The CP2532/CP2528 is specified over the -40℃ to +85℃ temperature range.
