25 MHz MSP430 CPUXV2 — what the core speed buys you
That clock rate, combined with a single-cycle hardware multiplier, handles sensor fusion loops and real-time control tasks without needing a separate DSP.
Industrial temperature range — where it runs
It is not specified for under-hood or downhole environments; if your design sees junction temperatures above 85°C, step up to the MSP430F5xx extended-range variants or add external thermal management.
Peripherals and connectivity — what is on-chip
Package and thermal — 64-VFQFN exposed pad
Supplied in a 64-VFQFN exposed-pad package (supplier device package 64-VQFN, 9x9 mm). The 53 I/O lines are available on the perimeter pads; no internal pull-up or pull-down is guaranteed at reset, so plan external resistors for open-drain buses.
For dual-sourcing resilience, the pin-compatible MSP430F5247IPMR (same Flash/RAM, same package) is a validated second source within the MSP430F5xx family.
