Key electrical and mechanical differences between the two devices
| Parameter | 5CEBA4F17C8N | 5CEBA4F17A7N | Why it matters |
|---|---|---|---|
| Family / Series | Cyclone V E | Cyclone V E | Both parts belong to the same Cyclone V E family, which is essential for functional substitutability and toolchain compatibility. |
| Logic Elements (LEs) | 49,000 | 49,000 | Identical logic density ensures the same design can fit without resource changes. |
| Package | FBGA-256 | FBGA-256 | Same package and pinout allow drop-in replacement on an existing PCB. |
| Operating Temperature Range | 0°C to +85°C (Commercial) | -40°C to +125°C (Automotive/Industrial) | The A7N variant supports a wider temperature range, making it suitable for harsher environments where the C8N may not be qualified. |
| Speed Grade | 8 (Fastest) | 7 (Slower) | Speed grade affects maximum operating frequency and timing closure; a slower grade may require design re-timing. |
| Supply Voltage (Core) | 1.1 V | 1.1 V | Identical core voltage means the same power supply design can be used for both devices. |
| Number of I/Os | 224 | 224 | Same I/O count ensures peripheral connectivity and board routing remain unchanged. |
| Embedded Memory (M10K) | 3,080 Kbits | 3,080 Kbits | Identical embedded memory capacity supports the same buffering and storage requirements. |
| Automotive Qualification | No | Yes (AEC-Q100) | Only the A7N is automotive-qualified, which is critical for automotive and safety-related applications. |

Frequently asked questions
What are the 5CEBA4F17C8N and 5CEBA4F17A7N devices?
Both are Intel (formerly Altera) Cyclone V FPGAs in the same 484-pin FineLine BGA (FBGA) package. The 5CEBA4F17C8N is specified with a commercial temperature grade and speed grade 8, while the 5CEBA4F17A7N is specified with an automotive temperature grade and speed grade 7.
What do the C8N and A7N suffixes indicate?
In the Cyclone V ordering code, C indicates the commercial temperature range (0°C to 85°C junction), A indicates the automotive temperature range (-40°C to 125°C junction), 8 and 7 are the speed grades, and N indicates lead-free (RoHS-compliant) packaging.
Do the 5CEBA4F17C8N and 5CEBA4F17A7N have the same logic density and package?
Yes. Both are Cyclone V E (5CE) devices with 49,000 logic elements (LEs) in the 484-pin FBGA package (17 mm x 17 mm, 1.0 mm pitch), so they share the same fabric capacity and physical footprint.
Can the 5CEBA4F17C8N and 5CEBA4F17A7N be used interchangeably?
Not directly. The 5CEBA4F17A7N has a wider automotive temperature range and a different speed grade than the 5CEBA4F17C8N. Any substitution must be validated against the target design's timing, power, and thermal requirements using Intel's official documentation.
Which device is better for automotive applications?
The 5CEBA4F17A7N is the automotive-grade option, rated for -40°C to 125°C junction temperature. The 5CEBA4F17C8N is commercial-grade (0°C to 85°C junction) and is not qualified for automotive temperature ranges.
How do the speed grades of the 5CEBA4F17C8N and 5CEBA4F17A7N compare?
The 5CEBA4F17C8N uses speed grade 8, while the 5CEBA4F17A7N uses speed grade 7. In Intel's Cyclone V speed grade nomenclature, a lower number indicates a faster speed grade, so the A7N device offers higher performance than the C8N device.
Are the 5CEBA4F17C8N and 5CEBA4F17A7N pin-compatible?
Yes. Both devices use the same 484-pin FBGA package with the same pinout, so they are pin-compatible at the package level. However, electrical and timing differences between the two speed grades and temperature grades must still be evaluated.
What configuration options do the 5CEBA4F17C8N and 5CEBA4F17A7N support?
Both Cyclone V E devices support standard configuration schemes including active serial (AS), passive serial (PS), fast passive parallel (FPP), and JTAG configuration, consistent with the Cyclone V device family documentation.
