The Capacitive Touch Sensor Evaluation Kit (part number 40P4637) features the MPR03X capacitive touch sensor controller, which is designed for low-power applications. It operates within a voltage range of 1.71 V to 2.75 V and has a low supply current of 6 ¬µA when monitoring two electrodes. The device supports up to three touch pads and utilizes an I¬=C interface for communication, allowing data rates of up to 400 kbits/sec. The MPR03X is housed in a compact 2 x 2 mm 8-lead ¬µDFN package, making it suitable for space-constrained designs. It includes intelligent touch detection capabilities and can operate in a temperature range of -40¬8C to +85¬8C. The kit requires only one external component, a 75 kOc resistor, and is ideal for applications such as PC peripherals, mobile phones, and lighting controls. The inclusion of an interrupt output enhances its functionality by notifying the host of electrode status changes.
