Replacement verdict
Compatible functional replacement candidate
The 5CEFA5U19I7N and 5CEFA2F23C7N are both Intel (Altera) Cyclone V FPGAs sharing the same core architecture, logic cell family, and 28 nm process technology, making them functionally related candidates. However, they differ in logic density, package footprint, and operating temperature grade, so the 5CEFA2F23C7N cannot serve as a direct drop-in replacement for the 5CEFA5U19I7N without design and PCB revision. The 5CEFA2F23C7N offers a smaller logic array and a different package, while the 5CEFA5U19I7N provides higher density and an industrial temperature rating. Designers should validate logic utilization, pinout, and thermal requirements before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA5U19I7N | 5CEFA2F23C7N | Why it matters |
|---|---|---|---|
| Family / Series | Cyclone V E | Cyclone V E | Same FPGA family ensures toolchain, IP, and pinout conventions are compatible, which is essential for substitutability. |
| Logic Elements (LE) | 77,000 | 25,000 | LE count determines available logic capacity; a large difference means the smaller device may not fit the same design. |
| Total RAM (M9K + MLAB) | 4,880 Kbit | 1,960 Kbit | On-chip memory affects buffering, FIFO depth, and data storage capability; insufficient RAM can block a design from fitting. |
| 18x18 Multipliers | 150 | 72 | DSP block count limits arithmetic throughput; fewer multipliers can reduce performance for signal-processing workloads. |
| Package | UBGA-484 | FBGA-484 | Package type and ballout affect PCB footprint and routing; different packages are not drop-in compatible. |
| Operating Temperature Range | -40°C to 100°C (Industrial) | 0°C to 85°C (Commercial) | Temperature grade determines suitability for industrial versus commercial environments and affects reliability margins. |
| Speed Grade | 7 (fastest) | 7 (fastest) | Speed grade sets maximum clock frequencies and timing closure difficulty; matching grades preserves performance targets. |
| Maximum User I/O | 224 | 224 | I/O count must meet interface requirements; identical counts simplify peripheral mapping between the two devices. |
| Core Supply Voltage | 1.1 V | 1.1 V | Core voltage must match board power design; identical values allow reuse of the same power delivery network. |

Frequently asked questions
What are the key differences between the 5CEFA5U19I7N and the 5CEFA2F23C7N?
The 5CEFA5U19I7N is a Cyclone V FPGA with 77,000 logic elements, 4,880 Kbits of embedded memory, and 224 18x18 multipliers in a 484-pin UBGA package, rated for industrial temperature range (I7). The 5CEFA2F23C7N is a Cyclone V FPGA with 25,000 logic elements, 1,400 Kbits of embedded memory, and 72 18x18 multipliers in a 484-pin FBGA package, rated for commercial temperature range (C7). The 5CEFA5U19I7N offers higher logic density, more memory, and more multipliers, while the 5CEFA2F23C7N is a smaller device in a different package.
Are the 5CEFA5U19I7N and 5CEFA2F23C7N pin-to-pin compatible?
No. The 5CEFA5U19I7N uses a 484-pin UBGA package (U19), while the 5CEFA2F23C7N uses a 484-pin FBGA package (F23). Although both have 484 pins, the package types and ball maps differ, so they are not pin-to-pin compatible. A direct drop-in replacement is not possible without PCB redesign.
Can the 5CEFA2F23C7N be used as a substitute for the 5CEFA5U19I7N in an existing design?
No, not directly. The 5CEFA2F23C7N has significantly fewer logic elements (25,000 vs 77,000), less embedded memory (1,400 Kbits vs 4,880 Kbits), and fewer multipliers (72 vs 224). It also uses a different package (FBGA vs UBGA) and a commercial temperature grade (C7) instead of industrial (I7). Substitution would require verifying that the reduced resources meet the design requirements and that the package and thermal specifications are acceptable.
What are the operating temperature ranges for these two FPGAs?
The 5CEFA5U19I7N is rated for industrial temperature range, typically -40°C to +100°C junction temperature (I7 grade). The 5CEFA2F23C7N is rated for commercial temperature range, typically 0°C to +85°C junction temperature (C7 grade). The industrial-grade device is suitable for harsher environments, while the commercial-grade device is intended for controlled environments.
Do both devices belong to the same FPGA family?
Yes. Both the 5CEFA5U19I7N and the 5CEFA2F23C7N are members of the Intel (formerly Altera) Cyclone V FPGA family. They share the same architecture, IP support, and development tools, but differ in logic density, memory resources, package, and temperature grade.
Which device has more embedded memory and multipliers?
The 5CEFA5U19I7N has more embedded memory and multipliers. It provides 4,880 Kbits of embedded memory and 224 18x18 multipliers, compared to 1,400 Kbits of embedded memory and 72 18x18 multipliers in the 5CEFA2F23C7N. This makes the 5CEFA5U19I7N better suited for applications requiring higher DSP throughput and larger on-chip buffering.
Are the package types of the 5CEFA5U19I7N and 5CEFA2F23C7N the same?
No. The 5CEFA5U19I7N is housed in a 484-pin UBGA (Ultra FineLine BGA) package, while the 5CEFA2F23C7N is housed in a 484-pin FBGA (FineLine BGA) package. The package designations U19 and F23 indicate different physical dimensions, ball pitches, and thermal characteristics, so they are not interchangeable without PCB layout changes.
What development tools support both the 5CEFA5U19I7N and 5CEFA2F23C7N?
Both devices are supported by Intel Quartus Prime software, including the Standard and Pro editions, depending on the specific device support list. The Cyclone V family is also supported by associated IP libraries, Nios II embedded design suite, and Signal Tap logic analyzer. Always verify the exact device support in the installed Quartus Prime version.
