The EP4CE15E22C8N packs 15408 logic elements and 516096 bits of embedded RAM in a 144-EQFP package with 81 user I/O.
Rated for 0°C to 85°C junction temperature, this part is suited for commercial and industrial indoor equipment.
The EP4CE15E22C8N has 81 user I/O and comes in a 144-LQFP Exposed Pad package (144-EQFP, 20x20 mm).
No direct drop-in replacement exists within the Cyclone IV family. The EP4CGX15BF14C8N (Cyclone IV GX) offers similar logic density (14400 LEs) but with a different package (484-BGA) and fewer I/O (72), requiring a board redesign.
Both share the same logic density (15408 LEs) and RAM (516096 bits), but the EP4CE15F17C8N uses a 256-BGA package with more I/O (179) versus the 144-EQFP with 81 I/O on the EP4CE15E22C8N. The package and I/O count are the deciding factors for board layout.
