16 MHz MSP430 — what the 2 KB Flash and 128 B RAM mean for the BOM
The MSP430G2201IRSA16R: The 10 general-purpose I/O lines, combined with the internal oscillator and brown-out reset, let it run with minimal external components.
Industrial temperature and package — deployment context
Surface-mount assembly is standard — no special reflow profile beyond the usual lead-free ramp.
Lifecycle status — active, no LTB risk
TI lists the MSP430G2201IRSA16R as Active. For new designs, the MSP430G2xx family has broad code compatibility across density options, so migrating to a larger Flash variant later is straightforward without a PCB change.
