16 MHz, 8 KB Flash, 512 B RAM — what the memory budget means
The 25 I/O lines, plus I²C, SPI, UART, IrDA, and LINbus connectivity, cover most serial-bridge and data-logging roles.
The EP suffix flags it as an extended-temperature / enhanced-product variant — not a commercial-grade part in an industrial wrapper.
32-VQFN (5x5) with exposed pad — layout and thermal handling
The 32-VQFN package (5x5 mm body) with exposed thermal pad needs a via-stitched ground paddle on the PCB to pull heat out of the die. Surface-mount only — no socket option.
At the low end, 1.8 V operation keeps the core alive during battery exhaustion — useful for last-gasp data logging.
This is a standard catalog part, not a phase-out or NRND line. The MSP430F2xx family has been in volume for years, so second-source risk is low: TI is the sole fab, but the architecture is stable and widely supported.
