The Texas Instruments MSP430FR5722IPWR is a 16-bit microcontroller built around the MSP430 CPUXV2 core, part of the MSP430 FRAM series. It carries 8KB of FRAM program memory and 1KB of SRAM, running at 8MHz. The FRAM memory type is the distinguishing feature here — it combines the non-volatility of Flash with near-instant write speeds and endurance orders of magnitude higher than Flash or EEPROM, making it a fit for data-logging, metering, and control loops where frequent writes to non-volatile memory are required. The 21 GPIOs and connectivity options including I²C, SPI, UART, and LINbus suit it for sensor aggregation and industrial fieldbus nodes.
