FRAM program memory is the distinguishing feature here: it combines non-volatile storage with write speeds and endurance far beyond Flash or EEPROM. The 32 KB capacity is sized for moderate firmware footprints plus a data-log buffer.
The MSP430FR58671IRGZR is end-of-life (hot) per TI. No successor is listed. For existing BOM lines, plan for last-time-buy or surplus sourcing.
Yes, it includes I²C and SPI connectivity, along with UART/USART and IrDA.
The supply voltage range is 1.8 V to 3.6 V.
