What this Cyclone IV E FPGA brings to the board
Core voltage runs 1.15 V to 1.25 V, commercial temperature range 0°C to 85°C. That limits it to indoor, conditioned environments — no engine bay or outdoor cabinet without active cooling. The 780-FBGA footprint is 29 mm square; plan for at least six layers on the PCB to route the 532 I/O out cleanly.
Sourcing and lifecycle reality
Comparing density tiers within Cyclone IV E
The EP4CE30F29C7N (28,848 LEs, 532 I/O) is the mid-range option. The EP4CE6F17C8N has only 6,272 LEs and 179 I/O — fine for glue logic or a small state machine, but you'll run out of fabric and pins fast. The EP4CE75F23C7N jumps to 75,408 LEs but drops to 292 I/O in a different BGA footprint. If your design needs the I/O count of the EP4CE30, the EP4CE75 won't fit without a board change.
