MSP430FR2433IRGET Description
The MSP430FR2433IRGET microcontroller (MCU) is a member of TI's most affordable family of MCUs for sensing and measurement applications, the MSP430TM Value Line sensing portfolio. In a tiny VQFN package (4 mm × 4 mm), the architecture, FRAM, and integrated peripherals are tuned to achieve prolonged battery life in portable and battery-powered sensing applications.
The MSP430FR2433IRGET ultra-low-power FRAM microcontroller platform from TI combines integrated FRAM that is distinct from other memory types with comprehensive ultra-low-power system architecture, enabling system designers to boost performance while reducing power usage. The low-energy rapid writing, adaptability, and endurance of RAM are combined with the nonvolatility of flash in FRAM technology.
