The Texas Instruments MSP430x20x3 ultralow power microcontrollers consist of several devices featuringdifferent sets of peripherals targeted for various applications. The architecture, combined with five low powermodes is optimized to achieve extended battery life in portable measurement applications. The MSP430x20x3 featuresa powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency.
The digitally controlled oscillator (DCO) of MSP430x20x3 allows wake-up from low-power modes to active mode in less than 1µs.

The MSP430x20x3 series is an ultralow-power mixed signal microcontroller with a built-in 16-bit timer, and tenI/O pins. In addition the MSP430x20x1 has a versatile analog comparator. The MSP430x20x2 andMSP430x20x3 have built-in communication capability using synchronous protocols (SPI or I2C), and a 10-bitA/D converter (MSP430x20x2) or a 16-bit sigma-delta A/D converter (MSP430x20x3).

Typical applications of MSP430x20x3 include sensor systems that capture analog signals, convert them to digital values, and thenprocess the data for display or for transmission to a host system. Stand alone RF sensor front end is anotherarea of application.
