The Texas Instruments MSP430 ultra-low-power microcontroller family includes multiple devices with peripheral sets for a variety of different applications. The architecture, with 5 low-power modes combined, is optimized to enable portablemeasurement applications to extend battery life. The device features a powerful 16-bit RISC CPU, 16-bit registers, and contributes to maximum code efficiency generators. The digitally controlled oscillator (DCO) allows wake-up from low-power mode in less active mode
1 microsecond.

The MSP430F21x2 series is a series of ultra-low-power microcontrollers with two built-in 16-bit timers, a fast 10-bit A/D converter integrated reference and data transfer controller (DTC), a comparator, built-in communication capabilities using a common serial communication interface, and up to 24 I/O pins.
