This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

Texas Instruments CapTIvate Mixed Signal MCUs 

Texas Instruments MSP430FR2670 series MCUs are ultra-low-power MCUs with CapTIvate Touch Technology for capacitive touch sensing applications.

CapTIvate technology is an integrated and autonomous touch-sensing solution supporting self- and mutual-capacitive electrodes in the same design. The MCUs also offer a high level of noise immunity and can be used with metal touch or in water rejection designs as well as other harsh environments.

The MCU is based on a powerful and efficient 16-bit RISC architecture that can operate from supplies down to 1.8V, with low current consumption in active and low-power modes. This is complemented by up to 64KB of low-power, nonvolatile FRAM with built-in ECC and configurable write protection.

The MCUs also feature a full peripheral set including enhanced serial communications and high-performance analog functionality.
