THEORY:

The Texas Instruments MSP430 family of ultralow 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 6 s. The MSP430F15x/16x/161x series are microcontroller configurations with

two built-in 16-bit timers, a fast 12-bit A/D converter, dual 12-bit D/A converter, one or two

universal serial synchronous/asynchronous communication interfaces (USART), I 2C, DMA,

and 48 I/O pins. In addition, the MSP430F161x series offers extended RAM addressing for

memory-intensive applications and large C-stack requirements. Typical applications include

sensor systems, industrial control applications, hand-held meters, etc.
