MSP430FR2433IYQWR Description

The MSP430FR2433 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. With the MSP430 ultra-low-power FRAM microcontroller platform from TI, system designers may boost performance while reducing energy consumption thanks to the combination of embedded FRAM and a comprehensive ultra-low-power system architecture. The low-energy rapid writing, adaptability, and endurance of RAM are combined with the nonvolatility of flash in FRAM technology.
