The Intel EP4CE55F29I7 is a Cyclone IV E FPGA with 55856 logic elements and 374 user I/O in a 780-BGA package. It carries 2396160 bits of embedded RAM across 3491 logic array blocks.
Pin compatibility across the Cyclone IV E family
The EP4CE55F29I7 shares the 780-ball BGA footprint with larger Cyclone IV E devices like the EP4CE75F23C7N. The 374 I/O count is the same across the EP4CE55 and EP4CE75 in this package; the difference is logic density (55856 vs 75408 LEs) and RAM (2396160 vs 2810880 bits). A board laid out for the EP4CE55 can accept the EP4CE75 as a drop-in upgrade if the design needs more gates — same ball map, same supply voltages. The 10CL055ZU484I8G (Cyclone 10 LP) is not pin-compatible: it uses a 484-ball package and a 1.0V core.
