Sensing & measurement features of MSP430™ MCUs

With the broadest sensing and measurement portfolio, MSP430 MCUs integrate analog and digital peripherals to reduce your BOM, ease design and improve performance. Functions range from ADCs, DACs, Op Amps, comparators and timers to more advanced peripherals such as capacitive touch and ultrasonic sensing.

Replace conventional buttons, sliders and wheels, with elegant touch sensing solutions resulting in improved system robustness and reliability in harsh environments.

A highly accurate and precise flow measurement with no moving parts delivers no wear and tear for longer operational life of water and gas flow meters.

Analog integration helps reduce external component count saving PCB area and simplifying layout while increasing flexibility with run-time configurability.

A low-power, 32-bit hardware engine designed for operations that involve vector-based signal processing such as FIR, IIR and FFT.

FRAM is a proven non-volatile memory technology that gives lower active power operation and 10^15 write cycles.
