Capacitive Touch Sense MCUs

Silicon Labs’ 8- and 32-bit capacitive touch sense microcontrollers (MCUs) enable implementation of touch buttons, sliders, wheels, capacitive proximity sensing and liquid level sensing. Featuring relaxation-oscillator (RO) technology and the world’s fastest charge-timing Capacitance to Digital Converter (CDC), these capacitive touch sense MCUs are ideal for a wide range of industrial and consumer electronics applications that can benefit from system power savings, tamper detection/proofing, motion sensing and gesture interpretation.
