Replacement verdict
Compatible functional replacement candidate
The 5CEFA2F23C8N and 5CEFA2F23I7 are functionally equivalent Cyclone V FPGA devices sharing identical logic density, package, and I/O configuration; the primary distinction is the temperature grade, with the C8N rated for commercial and the I7 for industrial operating ranges. The I7 variant can directly substitute the C8N in applications requiring extended temperature tolerance, while substitution in the reverse direction is only acceptable where the commercial temperature range is sufficient.

Frequently asked questions
What is the difference between the 5CEFA2F23C8N and the 5CEFA2F23I7?
The primary difference is the operating temperature grade. The 5CEFA2F23C8N is specified for the commercial temperature range (0°C to 85°C junction temperature), while the 5CEFA2F23I7 is specified for the industrial temperature range (-40°C to 100°C junction temperature). Both devices are functionally identical Cyclone V FPGA variants in the same FBGA-484 package with the same logic density and speed grade characteristics, but the I7 suffix denotes industrial temperature compliance.
Are the 5CEFA2F23C8N and 5CEFA2F23I7 pin-compatible?
Yes. Both devices are offered in the same 484-pin FineLine BGA (FBGA) package with identical pinouts as defined by the Intel (Altera) Cyclone V device family documentation. The package designator "F23" is common to both ordering codes, so the physical footprint and pin assignments are the same.
Can the 5CEFA2F23C8N be used as a drop-in replacement for the 5CEFA2F23I7?
Not unconditionally. Although the package and pinout are identical, the 5CEFA2F23C8N is rated only for the commercial temperature range (0°C to 85°C junction). If the target application requires operation below 0°C or above 85°C junction temperature, the commercial-grade device is not a valid substitute. The 5CEFA2F23I7 must be used where industrial temperature range compliance is required.
What FPGA family and logic density do the 5CEFA2F23C8N and 5CEFA2F23I7 belong to?
Both devices are members of the Intel (Altera) Cyclone V F-series FPGA family. The "A2" in the ordering code indicates the A2 density variant, which provides approximately 25,000 logic elements (LEs) along with associated embedded memory and DSP resources as documented in the Cyclone V device handbook.
Do the 5CEFA2F23C8N and 5CEFA2F23I7 share the same speed grade?
Yes. Both ordering codes include the "C8" speed grade designation, indicating the same speed grade (grade 8) for the core and I/O timing characteristics. The speed grade is independent of the temperature grade suffix, so timing performance is equivalent when both devices are operated within their respective rated temperature ranges.
Which device should be selected for an industrial-temperature application?
The 5CEFA2F23I7 should be selected for industrial-temperature applications. Its "I7" suffix denotes compliance with the industrial temperature range of -40°C to 100°C junction temperature, whereas the 5CEFA2F23C8N is limited to the commercial range of 0°C to 85°C junction temperature. Using the commercial-grade device outside its rated range is not supported by the manufacturer.
Are the 5CEFA2F23C8N and 5CEFA2F23I7 available in the same package type?
Yes. Both devices use the 484-pin FineLine BGA (FBGA) package, identified by the "F23" package code in the ordering part number. The package dimensions, ball pitch, and ball map are identical between the two temperature-grade variants.
Do the 5CEFA2F23C8N and 5CEFA2F23I7 differ in power supply requirements?
No. Both devices share the same Cyclone V A2 core and I/O power supply requirements as specified in the Cyclone V device datasheet. The core voltage, I/O bank voltages, and PLL supply requirements are determined by the device family and density, not by the temperature grade suffix. However, power consumption may vary slightly with operating temperature, so thermal analysis should be performed for the specific application conditions.
