Temperature grade and environment
Rated for 0°C to 85°C junction temperature. That is commercial-grade, not industrial or automotive.
Lifecycle and sourcing posture
Listed as Active on the manufacturer's lifecycle. That means Intel is still producing this density-speed grade, and franchised distribution carries it. No last-time-buy clock ticking. The Cyclone IV E family has been in the field for over a decade, so the design is mature — no surprise errata, but also no performance bumps coming. For a production BOM that needs a known-quantity FPGA with a stable supply, this is a safe pick. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time.
Package and footprint
Supplier device package 144-EQFP (20x20 mm). The exposed pad must be soldered to a ground-plane thermal land. The 81 I/O are distributed around the four sides.
