Sourcing now runs through the independent distribution channel, where we qualify available inventory against date-code provenance and manufacturer markings before quoting. An RFQ is the right next step to confirm current availability and pricing — the market for this part is finite and lot-dependent.
25 MHz CPUXV2 core — real-time loop headroom
The 25 MHz clock on the MSP430 CPUXV2 16-bit core gives a deterministic instruction-execution cadence typical of the MSP430 architecture — single-cycle on register operations, a few more on memory accesses. For control loops like sensor fusion, motor commutation, or protocol parsing at moderate baud rates, this keeps worst-case interrupt latency predictable without needing a cache or prefetch buffer. The 32 KB Flash and 6 KB RAM pair support firmware images that fit in the lower-density MSP430 tier; if your current codebase exceeds 28 KB of code or needs more than 5 KB of runtime data, the memory budget is tight and a migration to a larger member in the MSP430F5xx family would be needed.
80-ball BGA Microstar Junior — footprint reality
The 47 I/O lines fan out through the ball array; PCB breakout requires micro-vias or via-in-pad for a four-layer board. This is not a hand-solderable package — rework needs a hot-air station with a BGA nozzle and a stencil for reballing.
The 12-channel 10-bit ADC covers basic analog sampling for temperature, current, or voltage monitoring without an external converter.
