16 MHz MSP430 core in a 4x4 mm QFN — what you get
2 KB Flash and 128 B RAM — sizing the firmware budget
With 2 KB of Flash and 128 bytes of RAM, this MCU is aimed at small-footprint applications: a few lines of state-machine logic, a temperature or pressure readout, a relay timer, or a simple capacitive-touch button interface. The 16-bit core handles arithmetic efficiently, but the RAM is tight — any data buffer beyond a handful of bytes needs careful budgeting. The Flash is rated for 10k erase/write cycles typical of the MSP430 family, sufficient for calibration constants or configuration settings that change infrequently.
Industrial temperature range — not automotive-qualified
This part is not AEC-Q100 qualified. For automotive applications requiring AEC-Q100, consider the F280041PZQR.
16-QFN package — placement and thermal notes
The 16-QFN package (4x4 mm) is surface-mount with an exposed pad. The pad is electrically connected to the die substrate.
Active product status — no LTB risk
ROHS3 compliance is confirmed. The MSP430G2xx family remains a supported portfolio.
