Package and supply — board-fit constraints
The 256-FBGA (17×17 mm) footprint requires a four-layer or better PCB for the 1.15 V to 1.25 V core supply.
Active production — no end-of-life notice
The EP4CE22F17C8 carries an Active lifecycle status. No last-time-buy window or successor part has been announced.
Where it fits in the Cyclone IV E lineup
Compared to the smaller EP4CE6F17C8N (6,272 logic elements, 276,480 RAM bits), the EP4CE22F17C8 triples the logic fabric and more than doubles the block RAM — a meaningful step up for designs that need a Nios II soft processor with cache or a larger frame buffer. The I/O count difference (153 vs. 179) is minor; the 256-FBGA package is shared, so a board laid out for the EP4CE6 can accept the EP4CE22 without a PCB change, provided the core supply can deliver the higher dynamic current.
