16 MHz, 2 KB Flash, 256 B RAM — the sweet spot for a simple sensor node
The MSP430G2252IPW14: It packs 2 KB of Flash and 256 bytes of RAM — enough for a small state machine, a periodic sensor readout, or a basic I²C/SPI bridge, but tight enough that you will think twice before pulling in a library. The 14-TSSOP package gives you 10 I/O lines and an 8-channel 10-bit ADC, plus a USI module that handles I²C or SPI in software-selectable mode.
If your design lives in a heated office, the commercial-grade sibling would also work, but this part already covers the wider range without a cost penalty.
Active lifecycle — no supply-chain surprises
That means no end-of-life notice has been issued, no last-time-buy clock is ticking, and the part is still in normal production. For a new design, you are not forced into a second-source search or an LTB quantity calculation.
Package and footprint — 14-TSSOP
The 14-TSSOP pinout is consistent across the MSP430G2xx 14-pin options, so a drop-in upgrade is possible without a board spin.
