The 91 I/O are brought out to a 144-EQFP exposed-pad package (20x20 mm body). That is a hand-solderable, inspectable footprint — no BGA rework station needed.

The same Cyclone IV E logic density is available in a 256-ball BGA package as EP4CE6F17C8N (commercial temp) or EP4CE6F17C6N (same temp grade), offering 179 I/O instead of 91. These are pin-compatible at the die level but require a BGA assembly process. For higher logic density, the EP4CGX15BF14C8N (Cyclone IV GX) offers 14400 logic elements with transceivers, but in a different package and supply voltage.
The EP4CE6E22C6N and EP4CE6E22C8N share the same package, I/O count, and logic density. The 'C6' vs 'C8' suffix indicates a different speed grade — C6 is the faster grade. Whether it can replace depends on whether the design's timing closure was met with the slower C8 grade; if so, the C6 is a drop-in substitute with additional timing margin.
The difference is the speed grade: C6 is the faster timing grade, C8 is the standard speed. Both have identical logic resources (6272 LEs, 91 I/O) and the same 144-EQFP package. The C6 part offers tighter propagation delays and higher maximum clock frequency, which can help close timing on critical paths.
The datasheet is available from Intel's website under the Cyclone IV Device Handbook. The base product number EP4CE6 covers this variant; the full document includes pinout, electrical characteristics, and thermal specifications for the 144-EQFP package.
