75408 LEs — budget the fabric honestly
The EP4CE75F23C6 packs 75408 logic elements in a Cyclone IV E fabric, distributed across 4713 LABs/CLBs. That is a mid-range density slice — enough for a soft-core processor with peripheral set, a few DSP pipelines, and a memory controller without running the placer into congestion at 85% utilization. The 292 user I/O break out through a 484-BGA (23x23 mm) package. That ball pitch demands a 4-layer board minimum for fan-out; the inner rows need via-in-pad or microvias if you route all 292 signals to the periphery.
Block RAM and I/O — what fits in the 484-BGA
2810880 total RAM bits (roughly 2.8 Mbit) live on-chip as embedded memory blocks. That covers a 32 KB packet buffer with room for a dual-port register file and a FIFO for each high-speed I/O lane — but a full frame buffer at VGA resolution will push you to external SDRAM. The 0°C to 85°C junction temperature range covers most commercial indoor gear but not extended industrial or automotive ambient.
Active lifecycle — no last-time-buy pressure
For a BOM that already qualified this 484-BGA footprint, the active status means you can quote repeat builds without a last-time-buy clock running. The 10CL080YF484C8G (Cyclone 10 LP) shares the same 2810880 RAM bits and a close I/O count of 289 in the same 484-BGA — a potential second-source path if the design can absorb the core voltage difference.
