With features promoting reliable performance in noise-challenged applications, MSP430™ ULP FRAM MCUs include MSP430FR2633 lets designers build HMI with capacitive buttons, sliders, wheels, or proximity (BSWP) sensors. This 16-bit MCU, which incorporates CapTIvate™ technology, features non-volatile memory and can support 16 button self-capacitance as well as 64 button mutual-capacitance modes. Wake-on-touch hardware on chip can continuously scan up to 4 electrodes while CPU is shut down.
