What this FPGA delivers on the board
The Intel EP4CE55F23C7 is a Cyclone® IV E FPGA with 55,856 logic elements and 324 user I/O in a 484-ball FBGA. That logic density sits in the middle of the Cyclone IV E family — enough for a moderate bridge, a multi-axis motor controller, or a custom display interface, but not the top bin for DSP-heavy pipelines. The 484-BGA (23x23 mm) means a four-layer PCB is usually sufficient for routing the 324 I/O, though a six-layer board gives cleaner signal integrity on the outer banks. Temperature range is 0°C to 85°C junction — commercial grade. That rules out unheated enclosures or under-hood automotive, but is fine for indoor industrial cabinets, test equipment, and telecom central-office racks.
Sourcing and lifecycle
The EP4CE55F23C7 carries an Active product status — no last-time-buy notice, no NRND flag. That means it is still a valid selection for new BOMs and production spares without an imminent obsolescence clock. If you are qualifying a second source for supply resilience, the EP4CE75F23C7N (75,408 LEs, 292 I/O) is a drop-in package-compatible step-up with more logic and RAM, though the I/O count drops by 32 pins — verify your pinout before swapping.
