Replacement verdict
Compatible functional replacement candidate
The 5CEFA2F23C8N and 5CEFA7U19A7N are both Intel (Altera) Cyclone V FPGAs sharing the same device family, core architecture, and logic cell technology, making them functionally related candidates. However, they differ in logic density, package type, and speed grade, so the 5CEFA7U19A7N cannot be treated as a direct drop-in replacement for the 5CEFA2F23C8N without design and pinout validation. The higher-density 5CEFA7U19A7N offers greater logic resources but uses a different package and speed grade, requiring careful review of board layout, I/O assignment, and timing closure before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA2F23C8N | 5CEFA7U19A7N | Why it matters |
|---|---|---|---|
| Family | Cyclone V E | Cyclone V E | Same FPGA family ensures similar architecture, toolchain support, and IP compatibility. |
| Logic Elements (LE) | 25,000 | 150,000 | LE count determines the amount of logic that can be implemented; a large difference affects design capacity and substitutability. |
| Package | FBGA-484 | UBGA-484 | Package type and footprint must match for board-level drop-in compatibility. |
| Operating Temperature Range | 0°C to 85°C (Commercial) | -40°C to 125°C (Automotive/Industrial) | Temperature grade affects reliability and suitability for harsh environments. |
| Speed Grade | 8 | 7 | Speed grade impacts maximum operating frequency and timing closure; different grades may not meet the same performance targets. |
| Supply Voltage (Core) | 1.1 V | 1.1 V | Core voltage must match to ensure electrical compatibility and proper operation. |
| Number of I/O Pins | 224 | 224 | I/O count determines the number of external interfaces supported; matching counts aids pin-compatible substitution. |
| Embedded Memory (M9K) | 1,220 Kbits | 6,860 Kbits | On-chip memory capacity affects the ability to store data, buffers, and implement memory-intensive functions. |
| DSP Blocks (18x18) | 36 | 312 | DSP block count determines signal processing throughput and suitability for math-intensive applications. |
| PLLs | 4 | 4 | PLL count affects clock generation and distribution flexibility for multi-clock designs. |

Frequently asked questions
What are the key differences between the 5CEFA2F23C8N and the 5CEFA7U19A7N?
The 5CEFA2F23C8N is a Cyclone V E FPGA with 25,000 logic elements in a 484-pin FBGA package, while the 5CEFA7U19A7N is a Cyclone V E FPGA with 149,500 logic elements in a 484-pin UBGA package. They differ in logic density, package type, and speed grade.
Are the 5CEFA2F23C8N and 5CEFA7U19A7N pin-compatible?
No. The 5CEFA2F23C8N uses a 484-pin FBGA package, and the 5CEFA7U19A7N uses a 484-pin UBGA package. These are different package types with different ball maps and PCB land patterns, so they are not pin-compatible.
Can the 5CEFA2F23C8N be used as a direct substitute for the 5CEFA7U19A7N?
No. The 5CEFA7U19A7N offers significantly higher logic density (149,500 LEs vs. 25,000 LEs), a different package, and a different speed grade. A direct substitution would require a complete design re-evaluation, including logic capacity, pinout, and timing closure.
What are the operating temperature ranges for these two FPGAs?
Both the 5CEFA2F23C8N and the 5CEFA7U19A7N are specified for commercial temperature operation, typically 0°C to 85°C junction temperature, as defined by the Intel Cyclone V device datasheet for the C8 and A7 speed grade variants.
Do both devices belong to the same FPGA family?
Yes. Both the 5CEFA2F23C8N and the 5CEFA7U19A7N are members of the Intel Cyclone V E FPGA family, which shares common architecture, IP support, and development tools such as Quartus Prime.
Which device has higher logic capacity, and by how much?
The 5CEFA7U19A7N has higher logic capacity. It provides 149,500 logic elements, whereas the 5CEFA2F23C8N provides 25,000 logic elements, making the 5CEFA7U19A7N approximately six times larger in logic density.
Are the speed grades of the 5CEFA2F23C8N and 5CEFA7U19A7N the same?
No. The 5CEFA2F23C8N is a C8 speed grade device, and the 5CEFA7U19A7N is an A7 speed grade device. These speed grades have different timing characteristics and maximum operating frequencies, so timing analysis must be performed separately for each.
What package types are used by the 5CEFA2F23C8N and 5CEFA7U19A7N?
The 5CEFA2F23C8N uses a 484-pin FBGA package, while the 5CEFA7U19A7N uses a 484-pin UBGA package. Both are ball grid array packages, but the FBGA and UBGA variants have different physical dimensions and ball pitches.
