128 KB FRAM — the reason to pick this MSP430
Its standout feature is 128 KB of FRAM program memory, which combines non-volatile storage with fast write speeds and high endurance — no page-erase penalty, no wear-leveling needed for most data-logging applications. The 2K x 8 RAM handles stack and scratchpad. This part is aimed at industrial sensing, metering, and portable instrumentation where low power and data retention across power cycles matter more than raw compute.
For new designs, this removes the obsolescence risk that haunts older flash-based MSP430s.
