The 16 MHz core speed is the ceiling for this device; at that frequency the Flash needs zero wait states, so instruction throughput is deterministic — no timing surprises on tight loops.
It is ROHS3 compliant.
Yes, the 14-TSSOP package is not the standard 20-pin DIP on the LaunchPad, but the MSP430G2xx family shares the same core and peripheral set, so code developed on the LaunchPad can be ported with pin-mapping adjustments. The device is supported by TI's Code Composer Studio and Energia IDE.
