What this Cyclone IV E FPGA brings to the board
The Intel EP4CE15F23C8L is a Cyclone IV E FPGA with 15408 logic elements and 516096 total RAM bits in a 484-ball BGA. The 343 user I/O suit parallel-bus interfaces, video bridges, or wide memory controllers.
Temperature range and where it runs
Operating temperature spans 0°C to 85°C (junction). That covers indoor industrial environments such as factory-floor controllers, test equipment, or rack-mounted gear in a conditioned space.
How it compares to the Cyclone IV GX sibling
The EP4CGX15BF14C8N (Cyclone IV GX) is a functional peer with 14400 logic elements and 552960 RAM bits, but it drops to 72 I/O and uses a different 484-ball footprint. If your design needs the full 343 I/O, the GX part won't route your bus. If you need transceivers, the GX has them; the E family does not. No pin-compatible second source exists — these are different die and package layouts.
