CP2532/cp2528 product brief touch panel controller series 12/8 channels capacitive touch detection device copyright ?2007 chiphomer technology limited general description the CP2532/cp2528 is 12/8 channels capacitive touch panel controller, used for scroll, navigation and selection detection. the c ontroller contains spi or i 2 c 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) func tion ensures only one channel active each time. the range of power is 2.6v ~ 5.5v.
