Texas Instruments MSP430FR2422 Ultra-Low Power Microcontrollers

Texas Instruments MSP430FR2422 Ultra-Low Power Microcontrollers (MCUs) are part of the MSP430™ value line microcontroller (MCU) portfolio, TI’s lowest cost family of MCUs for sensing and measurement applications. The MSP430FR2422 MCUs provide 8KB of non-volatile memory with an 8-channel 10-bit ADC. The architecture, FRAM, and integrated peripherals, combined with extensive low-power modes, are optimized to achieve extended battery life in portable and battery-powered sensing applications. These MCUs combine uniquely embedded FRAM and holistic ultra-low-power system architecture, allowing system designers to increase performance while lowering energy consumption. FRAM technology combines the low-energy fast writes, flexibility, and endurance of RAM with the non-volatility of flash.
