Texas Instruments' MSP430 ultra-low-power microcontroller family includes multiple devices with peripheral sets for a variety of different applications. The architecture, with five low-power modes combined, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and attributes to maximize code efficiency and constant generator. The digitally controlled oscillator (DCO) allows wake-up from low-power mode in active mode in less than 6μs.

The MSP430F42x series is a microcontroller configuration of three independent 16-bit Sigma-Δ A/D converters, each with an integrated programmable gain differential amplifier input stage.
