80-LQFP (12x12 mm body), -40°C to 85°C industrial range. Supply 1.8 V to 3.6 V.
The MSP430F5515IPN is listed as active product status but flagged end-of-life (EOL). The last-time-buy window is open — final orders can still be placed, but the part will eventually be discontinued. Buyers should plan for a lifetime buy or a migration to a pin-compatible sibling.
It comes in an 80-lead LQFP (12x12 mm body, 0.5 mm pitch) — a standard surface-mount package for mid-complexity MCUs.
The supply range is 1.8 V to 3.6 V, covering single Li-ion cell and standard 3.3 V logic rails.
