Product Summary

The MSP430F1121AIPW is an ultralow power microcontroller. It consists 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 MSP430F1121AIPW 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 6μs. The application of the MSP430F1121AIPW include 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. Stand alone RF sensor front end is another area of application. The I/O port inputs provide single slope A/D conversion capability on resistive sensors.
