Replacement verdict
Compatible functional replacement candidate
The 5CEBA4F23C7N and 5CEBA4U15I7N are both Intel Cyclone V FPGAs sharing the same 49,000 LE logic density and core architecture, making them functionally related candidates. However, they differ in package type, pin count, and operating temperature grade, so a direct drop-in replacement is not possible without PCB redesign and thermal validation. The 5CEBA4U15I7N offers a wider industrial temperature range, while the 5CEBA4F23C7N provides a higher I/O count in a larger FBGA package. Designers should verify pinout compatibility, I/O requirements, and thermal conditions before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEBA4F23C7N | 5CEBA4U15I7N | Why it matters |
|---|---|---|---|
| Family / Series | Cyclone V E | Cyclone V E | Same FPGA family ensures toolchain, IP, and pinout compatibility for substitution. |
| Logic Elements (LE) | 49,000 | 49,000 | Identical logic capacity means equivalent design fit and resource utilization. |
| Package | FBGA-484 | UBGA-324 | Different package footprints and ball counts prevent direct PCB drop-in replacement. |
| Operating Temperature Range | 0°C to +85°C (Commercial) | -40°C to +100°C (Industrial) | Industrial grade supports harsher environments; commercial grade is limited to benign conditions. |
| Speed Grade | 7 | 7 | Same speed grade yields comparable timing closure and maximum operating frequency. |
| Supply Voltage (Core) | 1.1 V | 1.1 V | Matching core voltage allows reuse of the same power delivery design. |
| I/O Count | 224 | 176 | Fewer I/Os on the U15 package may limit peripheral interfaces and require redesign. |
| Embedded Memory | 3,080 Kbit | 3,080 Kbit | Equal on-chip memory supports the same buffering and storage requirements. |
| Transceiver Support | Not available (E variant) | Not available (E variant) | Neither device offers high-speed transceivers, so serial protocol needs must be met externally. |

Frequently asked questions
What are the key differences between the 5CEBA4F23C7N and the 5CEBA4U15I7N?
The 5CEBA4F23C7N is a Cyclone V E FPGA in a 484-pin FBGA package with a commercial temperature grade (0°C to 85°C junction), while the 5CEBA4U15I7N is a Cyclone V E FPGA in a 324-pin UBGA package with an industrial temperature grade (-40°C to 100°C junction). Both share the same 49,000 logic elements and 3,136 Kbits of embedded memory, but differ in package, I/O count, and operating temperature range.
Are the 5CEBA4F23C7N and 5CEBA4U15I7N functionally interchangeable?
No. Although both are Cyclone V E FPGAs with identical logic density and memory resources, they have different package footprints (484-pin FBGA vs 324-pin UBGA), different pin counts, and different maximum user I/O. The 5CEBA4F23C7N offers 224 user I/Os, while the 5CEBA4U15I7N offers 128 user I/Os. A direct drop-in replacement is not possible without PCB redesign.
What is the operating temperature range for each device?
The 5CEBA4F23C7N is rated for commercial temperature operation with a junction temperature range of 0°C to 85°C. The 5CEBA4U15I7N is rated for industrial temperature operation with a junction temperature range of -40°C to 100°C. The industrial-grade device is suitable for harsher environments.
Do both FPGAs have the same logic element count and embedded memory?
Yes. Both the 5CEBA4F23C7N and 5CEBA4U15I7N belong to the Cyclone V E family and feature 49,000 logic elements (LEs), 3,136 Kbits of M10K embedded memory, and 132 18x18 multipliers. The primary differences lie in packaging, I/O availability, and temperature grade.
Which device supports more user I/O pins?
The 5CEBA4F23C7N supports up to 224 user I/O pins in its 484-pin FBGA package. The 5CEBA4U15I7N supports up to 128 user I/O pins in its 324-pin UBGA package. Designs requiring higher I/O density should use the 5CEBA4F23C7N.
Can the 5CEBA4U15I7N be used as a substitute for the 5CEBA4F23C7N in an existing design?
No, not without significant redesign. The 5CEBA4U15I7N has a different package (324-pin UBGA vs 484-pin FBGA), fewer user I/Os (128 vs 224), and a different pinout. The PCB land pattern, routing, and thermal management would all require changes. Additionally, the industrial temperature grade of the 5CEBA4U15I7N may not be necessary if the original design only required commercial grade.
What are the typical applications for each device?
The 5CEBA4F23C7N, with its higher I/O count and commercial temperature range, is typically used in consumer, industrial control, and communication equipment operating in controlled environments. The 5CEBA4U15I7N, with its industrial temperature range and smaller package, is suited for automotive, industrial automation, and outdoor applications where space is constrained and wider temperature tolerance is required.
Are the power supply requirements the same for both FPGAs?
Yes. Both devices are Cyclone V E FPGAs and share the same core voltage (1.1 V), I/O voltage options (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V), and transceiver power requirements as specified in the Intel Cyclone V Device Handbook. However, actual power consumption may differ due to different I/O counts and operating temperatures.
