Rated -40 to 85 °C and 1.8 V to 3.6 V supply. Brown-out detect and POR handle startup glitches without an external supervisor.
Product status is Active; EOL-hot flag suggests early phase-out. For production BOM, lock in last-time-buy or qualify a pin-compatible sibling in the MSP430G2xx family.
The core runs at 16 MHz, which is typical for the MSP430G2xx value line — enough for sensor polling and simple control loops, not for heavy DSP.
The MSP430G2231 (2 KB Flash, 128 B RAM) shares the same 16-QFN footprint and pinout — a direct upgrade with more code space for firmware growth.
