FRAM-based MSP430: what sets this MCU apart
Its program memory is 32 KB of FRAM — ferroelectric RAM that combines the non-volatility of Flash with byte-addressable, single-cycle write speed and effectively unlimited endurance. That makes it a different animal from conventional Flash MCUs: you can treat the FRAM as both code space and data-logging storage without worrying about sector erase times or wear-leveling. Connectivity covers I²C, IrDA, and SPI — enough for metrology front-ends, sensor fusion hubs, or industrial communication nodes.
64-lead QFN — board-level note
The exposed pad is typically tied to VSS. Surface-mount assembly with MSL-precaution applies — standard reflow profiles for lead-free solder work here.
