Product Brief CP2532/CP2528 Touch Panel Controller Series 12/8 channels Capacitive Touch Detection Device General www.datasheet4u.com Description NC ADD1/SDI/SEN0 ADD0/CSN/SEN1 DVSS DVSS DVDD DVDD DVDD SCL/SCLK/MOT1 SDA/SDO/MOT0 D0 D1 33 32 31 29 28 27 26 30 25 24 23 22 21 20 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.
