MSP430F2252IRHAR

Product Summary

The MSP430F2252IRHAR is an ultra low-power microcontroller. It consists 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 MSP430F2252IRHAR 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 μs. The applications of the MSP430F2252IRHAR 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 radio-frequency (RF) sensor front ends are another area of application.
