MSP430F2121IRGER
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 ¦Ì s.
Typical applications include sensor systems that capture analog signals, convert themto digital values, and then process the data for display or for transmission to a host system.
