Package and footprint — 144-EQFP with exposed pad
The 144-EQFP (20x20 mm) with exposed pad requires a thermal land pattern on the PCB. The exposed pad must be soldered to a ground plane for thermal relief and electrical grounding.
Lifecycle and sourcing reality
The EP4CE15E22C8L is listed as Active in production. No end-of-life notice or last-time-buy schedule exists. That means you can qualify it into a new BOM without an immediate obsolescence clock.
Temperature grade — commercial only
Rated 0°C to 85°C (junction). This is a commercial-temperature device. It will not meet the -40°C requirement for outdoor telecom cabinets, engine-bay electronics, or cold-chain logistics. If your application sees freezing temperatures, look at the EP4CE10U14I7N which is rated -40°C to 100°C, but be aware of the logic-density trade-off (10320 LEs vs 15408).
