open-in-new Find other MSP430 ultra-low-power MCUs

Description

The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs.

The MSP430G2x55 series are ultra-low-power mixed signal microcontrollers with built-in 16-bit timers, up to 32 I/O touch-sense-enabled pins, a versatile analog comparator, and built-in communication capability using the universal serial communication interface.

Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values, and then process the data for display or for transmission to a host system.
