Product details
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.
