Replacement verdict
Compatible functional replacement candidate
The 5CEFA2F23C8N and 5CEFA2M13C7N are both Intel Cyclone V FPGAs sharing the same logic density, transceiver count, and core architecture, making them functionally interchangeable for most designs. However, they differ in package type, operating temperature grade, and speed grade, so validation against the target application's thermal and mechanical requirements is essential before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA2F23C8N | 5CEFA2M13C7N | Why it matters |
|---|---|---|---|
| Package / Case | FBGA-484 | MBGA-383 | The physical footprint and ball pitch differ, so the two devices are not drop-in compatible on the same PCB land pattern. |
| Number of I/Os | 224 | 112 | Available user I/O count directly limits how many external interfaces and peripherals can be connected. |
| Logic Elements (LE) | 25000 | 25000 | Logic capacity determines the complexity of digital designs that can be implemented in the fabric. |
| Total RAM Bits | 1956864 | 1956864 | Embedded memory capacity affects buffering, FIFO depth, and on-chip data storage capability. |
| Operating Temperature Range | 0°C to 85°C (Commercial) | 0°C to 85°C (Commercial) | The temperature grade must match the target application's environmental conditions for reliable operation. |
| Speed Grade | 8 | 7 | A faster speed grade allows higher clock frequencies and tighter timing closure for demanding designs. |
| Supply Voltage | 1.1 V Core | 1.1 V Core | Core voltage must match the board power design to avoid damage or unreliable operation. |
| Mounting Type | Surface Mount | Surface Mount | Mounting style determines the assembly process and whether the part suits the intended PCB technology. |

Frequently asked questions
What are the 5CEFA2F23C8N and 5CEFA2M13C7N devices?
Both are Intel (formerly Altera) Cyclone V F-series FPGAs from the same 5CEFA2 device family. The 5CEFA2F23C8N is a 484-pin FineLine BGA (FBGA) device with a speed grade of 8, while the 5CEFA2M13C7N is a 383-pin Micro FineLine BGA (MBGA) device with a speed grade of 7.
Do the 5CEFA2F23C8N and 5CEFA2M13C7N have the same logic density?
Yes. Both devices belong to the same Cyclone V F-series 5CEFA2 density tier, which provides approximately 25,000 logic elements (LEs), 9,430 adaptive logic modules (ALMs), and 1,880 Kbits of embedded memory. The primary differences are package, pin count, and speed grade.
Can the 5CEFA2F23C8N and 5CEFA2M13C7N be used interchangeably on the same PCB?
No. The 5CEFA2F23C8N uses a 484-pin FBGA package, while the 5CEFA2M13C7N uses a 383-pin MBGA package. These packages have different physical dimensions, ball counts, ball pitches, and pinouts, so they are not footprint-compatible and cannot be interchanged without a PCB redesign.
What is the difference in speed grade between the 5CEFA2F23C8N and 5CEFA2M13C7N?
The 5CEFA2F23C8N is specified with speed grade 8, and the 5CEFA2M13C7N is specified with speed grade 7. In Intel Cyclone V nomenclature, a lower speed grade number indicates a faster device. Therefore, the 5CEFA2M13C7N (grade 7) offers faster timing performance than the 5CEFA2F23C8N (grade 8).
What are the operating temperature ranges for these two FPGAs?
Both the 5CEFA2F23C8N and 5CEFA2M13C7N are specified for commercial temperature operation, typically 0°C to 85°C junction temperature (TJ), as indicated by the "C" in the ordering code. Industrial-temperature versions would carry a different suffix and should be selected if a wider range is required.
Which device offers more user I/O pins, the 5CEFA2F23C8N or the 5CEFA2M13C7N?
The 5CEFA2F23C8N, with its larger 484-pin FBGA package, provides more user I/O pins than the 5CEFA2M13C7N, which is housed in the smaller 383-pin MBGA package. The exact user I/O count for each device should be confirmed from the Intel Cyclone V device pin-out files and datasheet for the specific package option.
Are the 5CEFA2F23C8N and 5CEFA2M13C7N lead-free and RoHS compliant?
Both devices use the "N" suffix in their ordering codes, which indicates lead-free (Pb-free) packaging and RoHS compliance per Intel's ordering code conventions for Cyclone V devices. Designers should still verify the specific product change notices and material declarations from Intel or authorized distributors for the latest compliance status.
Which configuration and transceiver features are common to both devices?
As members of the Cyclone V F-series 5CEFA2 tier, both the 5CEFA2F23C8N and 5CEFA2M13C7N share the same core FPGA architecture, including logic array, embedded memory blocks, variable-precision DSP blocks, and general-purpose PLLs. Differences arise from the package pin count, which affects the number of available I/O banks and high-speed interfaces that can be routed out.
