528 I/O in a 780-BGA. The 780-FBGA (29x29 mm) footprint matches larger Cyclone IV parts.
The EP4CE115F29I8L carries an Active product status. For volume procurement, the part is sourced through independent distribution and quoted to order against an RFQ.
The key difference is the temperature grade: the I8L suffix indicates the industrial range (-40°C to 100°C TJ), while the C7 suffix indicates the commercial range (0°C to 85°C TJ). The logic density, I/O count, and package are identical. Choose the I8L for environments that see freezing or sustained heat; the C7 is fine for indoor, climate-controlled equipment.
The core voltage must be held between 0.97V and 1.03V — a 1.0V rail with 1% tolerance is the practical minimum. The 3981312 total RAM bits are on-chip block memory; no external memory is required for the fabric to operate, though you may add external DDR or SRAM via the I/O if your application needs more storage.
The Intel 10CL120ZF780I8G (Cyclone 10 LP) is the closest functional peer: same 780-FBGA package, same 3981312 RAM bits, and 119088 logic elements versus 114480. The I/O count is 525 versus 528 — three pins fewer, which is negligible for most layouts. The 10CL120 is a newer architecture but pin-compatible enough that a board designed for the EP4CE115 can often take the 10CL120 with minor Quartus project changes.
