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 lowpower 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.
