Product Brief
CP2532/CP2528
Touch Panel Controller Series
12/8 channels Capacitive Touch Detection Device
www.datasheet4Gu.econmeral Description
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 -40to +85temperature
range.
