The 28-SOIC (7.50 mm width) package is a standard footprint for wave-solder assembly and rework, and the 22 I/O lines map cleanly to a 16-pin header plus a few discrete signals. No AEC-Q100 qualification is listed, so skip it for any vehicle powertrain or chassis-domain application.
Lifecycle and sourcing — what to expect
The MSP430F123IDWR carries an EOL-hot lifecycle marker, meaning TI has announced end-of-life for this device. Production is still active per the listing, but the window for last-time buys is narrowing.
