That is commercial-grade, not industrial or automotive.
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.
Supplier device package 144-EQFP (20x20 mm). The 81 I/O are distributed around the four sides.
0°C to 85°C junction temperature. That is commercial-grade; not rated for industrial or automotive environments.
The suffix 'C9L' vs 'C8L' indicates a different speed grade. The 'C9' is the standard-speed tier; 'C8' is one step faster. All other specs — logic density, I/O count, package, temperature range — are identical between the two.
144-LQFP Exposed Pad (20x20 mm body, 0.5 mm pitch). The exposed pad on the bottom is the primary thermal path and must be soldered to a ground plane. 81 I/O are distributed around the four sides.
