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 . 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.
