DESCRIPTION

The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consist 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 MSP430G2x52 and MSP430G2x12 series of microcontrollers are ultra-low-power mixed signal

microcontrollers with built-in 16-bit timers, and up to 16 I/O capacitive-touch enabled pins and built-in

communication capability using the universal serial communication interface and have a versatile analog

comparator. The MSP430G2x52 series have a 10-bit A/D converter. For configuration details see Table 1.

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.
