It packs 4 KB of Flash and 256 bytes of RAM — enough for a single control loop, a sensor interface, or a simple serial bridge.
Housed in a 20-pin TSSOP (4.40 mm wide), it's a surface-mount part for standard reflow assembly.
Energia supports MSP430G2xx value-line devices, and the MSP430G2302IPW20R is part of that series. Programming through Energia should work, though you'll need to select the correct board profile for the 20-TSSOP variant.
