39600 logic elements — what that means for the BOM
At 39600 logic elements, this part sits in the mid-density tier of the Cyclone IV E family. That is enough fabric for a modest soft-core processor, a few serial controllers, and some glue logic. The 2475 LABs/CLBs give the place-and-route tool enough columns to keep timing closure manageable at moderate clock rates. The 532 I/O in a 780-BGA (29x29 mm) means the board designer gets plenty of escape routes, but the fine-pitch BGA demands a multi-layer PCB with microvias or blind vias for full routability. Plan for at least six layers if using all I/O banks.
Lifecycle and sourcing reality
The EP4CE40F29I8LN carries an EOL/hot lifecycle stage. While the official product status is listed as active, the EOL-hot flag signals that this part is in its last-time-buy window or very close to it. For a BOM line that needs this exact density and I/O count, the window to commit is now — waiting a quarter could mean sourcing from surplus channels at a premium. We source and quote this part to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
