16 MHz MSP430 core with 2 KB Flash — what fits in that memory budget
The 2 KB Flash limits firmware to compact state machines, sensor polling loops, and simple control algorithms — think a single-wire temperature sensor interface or a battery-monitor routine. The 256-byte RAM holds a few frames of sensor data or a small communication buffer; anything larger needs external SRAM or a part from the higher-density MSP430G2xx siblings.
20-TSSOP package — footprint and layout notes
Housed in a 20-TSSOP (4.40 mm width, 0.65 mm pitch), this is a surface-mount package suited for automated assembly. The 0.65 mm pitch is fine enough that hand-soldering is possible with care, but reflow is preferred. No exposed thermal pad — the package relies on the leadframe and PCB copper for heat dissipation.
The MSP430G2xx family has broad distribution support, and the active status means standard lead times apply through authorized channels.
Sourcing this part to your BOM
If your assembly line feeds from tape-and-reel, check the reel suffix (typically 'R' appended, e.g. MSP430G2252IPW20R) to match the feeder. The active lifecycle means no supply discontinuity risk for the foreseeable future, making it a clean fit for both prototyping and volume production.
