Product Brief
CP2508
Touch Panel Controller Series
8 channels Capacitive Touch Sensor Controller
www.datasheet4Gu.econmeral Description
The CP2508 is 8 channels capacitive touch panel controller, used for
scroll, navigation and selection detection. The controller contains SPI or
I2C serial interface, extended GPIO, high PSRR LDO and in-built OSC.
The touch status can be read via serial interface or GPIO. Particularly,
adjacent sensor suppression (ASS) function ensures only one channel
active each time. The range of power is 2.8V ~ 3.6V.
Low-power operation makes the CP2508 ideal for battery-operated
systems, such as multimedia portable product. The CP2508 is specified
over the -40to +85temperature range.
QFN-32
- 40 oC ~ 85 oC
