MSP430FR2433IYQWR

The MSP430FR2433 microcontroller (MCU) is a device in the value series detection product portfolio, suitable for detection and measurement applications. This architecture, combined with FRAM and integrated peripherals and multiple low-power modes, is optimized to extend the battery life of applications using a small VQFN package (4mm×4mm). The ultra-low-power FRAM microcontroller platform combines unique embedded FRAM with a comprehensive ultra-low-power system architecture, enabling system designers to improve performance while reducing energy consumption. FRAM technology combines the low-power fast writing, flexibility, and durability of RAM with the non-volatility of flash memory. The MSP430FR2433 MCU is supported by an ecosystem consisting of various software and hardware resources, and is accompanied by reference designs and code examples to help speed up the design process.
