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 MSP430G2332 series of microcontrollers are ultra-low-power mixed signal microcontrollers with built-in

16-bit timers, and up to 16 I/O touch sense enabled pins and built-in communication capability using the

universal serial communication interface. The MSP430G2332 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.
