Replacement verdict
Compatible functional replacement candidate
The 5CEFA2F23C8N and 5CEFA2M13C6N are both Intel (Altera) Cyclone V FPGAs sharing the same 25K logic element fabric, making them functionally interchangeable at the device level. However, they differ in package type, operating temperature grade, and speed grade, so the 5CEFA2M13C6N is not a direct drop-in replacement without PCB redesign and timing revalidation. The 5CEFA2F23C8N offers a larger FBGA-484 package with commercial temperature range and speed grade 8, while the 5CEFA2M13C6N uses a compact MBGA-383 package with industrial temperature range and speed grade 6. Designers must verify footprint compatibility, thermal requirements, and timing closure before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA2F23C8N | 5CEFA2M13C6N | Why it matters |
|---|---|---|---|
| Package / Case | FBGA-484 | MBGA-383 | Different package footprints and ball counts are not drop-in compatible; PCB layout and assembly must be redesigned. |
| Number of I/Os | 224 | 112 | Fewer user I/Os limits peripheral and interface expansion, affecting system connectivity options. |
| Logic Elements (LEs) | 25,000 | 25,000 | Identical logic capacity means equivalent programmable logic resources for the same design complexity. |
| Total RAM Bits | 1,843,200 | 1,843,200 | Matching embedded memory supports the same buffering and data storage requirements. |
| Operating Temperature Range | 0°C to 85°C (Commercial) | 0°C to 85°C (Commercial) | Same temperature grade determines suitability for the same ambient and thermal environments. |
| Speed Grade | 8 (Fastest) | 6 (Faster) | A slower speed grade reduces maximum operating frequency and may require timing closure changes. |
| Supply Voltage - Core | 1.1 V | 1.1 V | Identical core voltage allows reuse of the same power supply design and decoupling network. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style is compatible with standard SMT assembly processes. |
| RoHS Status | RoHS Compliant | RoHS Compliant | Both meet environmental regulations, avoiding compliance issues in regulated markets. |

Frequently asked questions
What are the 5CEFA2F23C8N and 5CEFA2M13C6N devices?
Both are Intel (formerly Altera) Cyclone V F-series FPGAs from the 5CEFA2 family. The 5CEFA2F23C8N uses a 484-pin FBGA package (23 mm body, F23 suffix) with speed grade C8, while the 5CEFA2M13C6N uses a 383-pin Micro FBGA package (13 mm body, M13 suffix) with speed grade C6.
Do the 5CEFA2F23C8N and 5CEFA2M13C6N have the same logic density?
Yes. Both devices are members of the Cyclone V 5CEFA2 density tier, which provides approximately 25,000 logic elements (LEs), 9,430 adaptive logic modules (ALMs), and 1,220 Kbits of embedded M10K memory, per Intel Cyclone V device documentation.
What is the difference in speed grade between the 5CEFA2F23C8N and 5CEFA2M13C6N?
The 5CEFA2F23C8N is rated at speed grade C8, while the 5CEFA2M13C6N is rated at speed grade C6. In Intel's Cyclone V naming convention, a lower speed grade number indicates a faster device, so the C6 device supports higher maximum operating frequencies than the C8 device.
Are the 5CEFA2F23C8N and 5CEFA2M13C6N pin-to-pin compatible?
No. The 5CEFA2F23C8N uses a 484-pin FBGA package, whereas the 5CEFA2M13C6N uses a 383-pin Micro FBGA package. The different pin counts, ball maps, and package dimensions mean they are not drop-in replacements and require different PCB footprints.
Can the 5CEFA2F23C8N and 5CEFA2M13C6N be used interchangeably in the same design?
Not without redesign. Although both share the same Cyclone V 5CEFA2 logic density, they differ in package, pin count, and speed grade. A design targeting one device must be recompiled, re-pin-assigned, and re-timed for the other, and the PCB layout must accommodate the respective package footprint.
What are the typical applications for the 5CEFA2F23C8N and 5CEFA2M13C6N?
Both devices target cost-sensitive, low-power applications such as industrial control, motor control, protocol bridging, and embedded vision. The 5CEFA2M13C6N's smaller 13 mm Micro FBGA package suits space-constrained designs, while the 5CEFA2F23C8N's 23 mm FBGA package offers more user I/O and easier routing for larger boards.
Do both devices support the same configuration and transceiver options?
Both are Cyclone V F-series FPGAs and support configuration via active serial, passive serial, JTAG, and parallel flash interfaces. However, transceiver availability and high-speed interface support depend on the specific package and device variant; designers should verify the exact resource counts in the Intel Cyclone V Device Handbook for each ordering code.
Which device should be selected for a new design, 5CEFA2F23C8N or 5CEFA2M13C6N?
Selection depends on board space, I/O count, and timing requirements. Choose the 5CEFA2M13C6N when a compact 13 mm Micro FBGA package and higher speed grade (C6) are needed. Choose the 5CEFA2F23C8N when a larger 23 mm FBGA package with more pins and I/O is required, accepting the slower C8 speed grade.
