MSP430F2121

Product Summary

The MSP430F2121 is an ultralow power microcontroller consisting 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 MSP430F2121 features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1μs. The MSP430F2121 is an ultralow-power mixed signal microcontroller with a built-in 16-bit timer, versatile analog comparator and sixteen I/O pins.
