Product details

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.

Frequently asked questions

What does the 16 MHz speed mean for a control loop?

At 16 MHz, the MSP430 CPU16 executes most single-cycle instructions in 62.5 ns. For a 10 kHz sensor read-and-actuate loop, the MCU spends about 0.6% of the cycle on overhead, leaving the rest in sleep mode — which keeps average current in the microamp range.
