Obsolete — sourcing reality for this MSP430
Texas Instruments has designated the MSP430F5227IZQE as obsolete (EOL). No official successor order code is listed in the available records. For a BOM line that requires this exact MPN, the only channel is the independent surplus and broker market. We source and quote this part to order against an RFQ — availability and current pricing are confirmed at quote time. If you are designing a new board, consider a current-production MSP430F5xx or MSP430F6xx variant in a compatible package; for an existing build, verify the firmware footprint and pinout before substituting.
Temperature grade and environment
Rated for -40°C to 85°C operating ambient, this is an industrial-temperature-grade MCU. Suitable for outdoor telecom enclosures, factory-floor controllers, engine-bay-adjacent electronics (not directly on-engine), and portable instruments that see seasonal temperature swings. The 1.8 V to 3.6 V supply range lets it run from two alkaline cells or a single Li-ion through a regulator.
