Texas Instruments MSP430FR6972 16MHz-Mikrocontroller mit sehr geringem Stromverbrauch

Texas Instruments MSP430FR6972 16MHz Ultra-Low Power Microcontrollers consists of several devices featuring embedded non-volatile FRAM. They include a 16-bit CPU, and different sets of peripherals targeted for various applications. The architecture, FRAM, and peripherals, combined with seven low-power modes, are optimized to achieve extended battery life in portable and wireless sensing applications. FRAM is a new non-volatile memory that combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash, all at lower total power consumption.
