8 MHz core — timing budget for UART and ADC
At 8 MHz, the core handles UART and ADC tasks. The internal oscillator saves a crystal on the BOM.
EOL hot — sourcing reality
The MSP430F147IRTDT is flagged as EOL hot, meaning the manufacturer has discontinued production. For new designs, look at the MSP430F2xx or MSP430FRxx families. For existing BOMs, this part is available through independent distribution on a quoted-to-order basis against an RFQ.
64-VFQFN rework — will it survive the hot air?
The 9x9 mm package has an exposed thermal pad. Preheating the board reduces rework risk.
