Sensor Control Unit (TSCU) for capacitive touch sensors added to standard peripherals. System control as well as electrostatic capacitive touch detection of a maximum of 28 channels of input on a single chip. Perfect for customers wanting stable touch detection even in the rigorous noisy environments demanded by consumer and industrial applications, and customers considering system cost reduction by integrating system control and touch detection on a single chip. Maximum operating frequency is 20 MHz. 64-pin package is available.
