1.3 Description

The TI MSP family of ultra-low-power microcontrollers consists of several devices that feature 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 the device to wake up from low-power modes to active mode in less than 1 µs.

The MSP430G2x03 and MSP430G2x33 devices are ultra-low-power mixed-signal microcontrollers with built-in 16-bit timers, up to 24 I/O capacitive-touch enabled pins, and built-in communication capability using the USCI. In addition, the MSP430G2x33 family members have a 10-bit ADC. See Section 3 for configuration details.

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.
