混合信号微控制器 MIXED SIGNAL MICROCONTROLLER

description

The Texas Instruments MSP430 family of ultralow 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 6 μs.

Low Supply-Voltage Range: 1.8 V to 3.6 V
