MSP430F235TPMR

Product Summary

The MSP430F235TPMR is an ultra-lowpowermicrocontroller. 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 portablemeasurement applications. The MSP430F235TPMR features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The calibrated digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 μs. Typical applications of the MSP430F235TPMR include sensor systems, industrial control applications, hand-held meters, etc.
