Product details

Lifecycle and sourcing reality

The MSP430FR58471IRHAR is end-of-life hot (EOL hot). TI has announced discontinuation; the last-time-buy window is closing. For new designs, choose a current-production MSP430FRxx variant. For existing designs, secure last-buy quantities now. We source this part through independent distribution and quote to order.

Voltage supply and temperature grade

The supply range is 1.8 V to 3.6 V, so it runs from two alkaline cells or a single Li-ion without a regulator. Operating temperature spans -40°C to 85°C, which covers outdoor telecom cabinets, factory-floor enclosures, and under-hood automotive auxiliary modules — anything that sees a hot day or a cold start.

Frequently asked questions

Is the MSP430FR58471IRHAR obsolete or nearing end of life?

Yes, the MSP430FR58471IRHAR is flagged as end-of-life hot (EOL hot), meaning TI has announced discontinuation. Plan for a last-time-buy or migrate to a current-production MSP430FRxx variant.

What is the MSP430FR58471IRHAR operating voltage?

The supply voltage range is 1.8 V to 3.6 V, allowing direct operation from two alkaline cells or a single Li-ion battery.

Is MSP430FR58471IRHAR compatible with MSP430FR58471?

The base product number is MSP430FR58471, so the IRHAR suffix indicates the specific package (40-VQFN) and tape-and-reel packaging. The core MCU is the same; verify the package variant matches your board footprint.
