illustrate

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

The MSP430x11x1 family is an ultra-low-power mixed-signal microcontroller with a built-in 16-bit timer, multifunction analog comparator and fourteen I/O pins.

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