What this Cyclone IV E FPGA brings to the board
The Intel EP4CE40F23C6N is a Cyclone IV E FPGA packing 39600 logic elements and 328 user I/Os in a 484-ball BGA. It carries 1161216 total RAM bits for on-chip buffering and small state machines. The 1.15 V to 1.25 V core supply and commercial temperature range (0°C to 85°C) make it a fit for indoor, non-condensing environments like industrial control panels, test equipment, and communications gear where you need moderate gate density without the power budget of a high-end part.
39600 logic elements — what that means for your design
39600 logic elements and 2475 LABs/CLBs support soft-core processor and glue logic implementations.
Lifecycle and sourcing reality
The EP4CE40F23C6N is listed as Active — no EOL notice, no last-time-buy pressure. That makes it a safe pick for production runs over the next few years. For dual-sourcing or a drop-in alternative, the EP4CE40F29C8 shares the same logic density and RAM but offers 532 I/O in a larger 484-ball package — verify your PCB footprint before swapping. The Cyclone 10 LP parts (10CL040YU484C8G, 10CL040YU484C6G) match the logic and RAM but use a different core voltage and package; not a direct pin-for-pin replacement without a board spin.
Temperature grade and where it goes
Rated for 0°C to 85°C junction temperature — commercial grade for indoor environments.
