Replacement verdict
Not a drop-in replacement
The 5CEFA5U19I7N and 5CEFA2F23I7 are not functionally interchangeable. Although both are Intel Cyclone V FPGAs sharing the same speed grade and industrial temperature range, they differ fundamentally in logic density, package footprint, and available user I/O, making a direct board-level substitution infeasible without a complete redesign.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA5U19I7N | 5CEFA2F23I7 | Why it matters |
|---|---|---|---|
| Family / Series | Cyclone V E | Cyclone V E | Same FPGA family ensures toolchain, IP, and pinout conventions are compatible, easing migration. |
| Logic Elements (LE) | 77,000 | 25,000 | LE count determines available logic capacity; a large mismatch limits design portability. |
| Total RAM (M9K + MLAB) | 4,880 Kbit | 1,960 Kbit | On-chip memory affects buffering, FIFO depth, and whether a design fits without external RAM. |
| 18x18 Multipliers | 150 | 72 | DSP block count limits parallel arithmetic throughput for signal-processing workloads. |
| Package | UBGA-484 | FBGA-484 | Package type and ballout must match the PCB footprint for a drop-in replacement. |
| Maximum User I/O | 224 | 224 | I/O count determines how many peripherals and interfaces can be connected simultaneously. |
| Transceiver Count | 0 | 0 | Presence of high-speed transceivers dictates support for protocols like PCIe or Gigabit Ethernet. |
| Speed Grade | 7 (Industrial) | 7 (Industrial) | Speed grade and temperature range affect timing closure and operating environment compatibility. |
| Core Supply Voltage | 1.1 V | 1.1 V | Core voltage must match the board power design to avoid electrical damage or malfunction. |

Frequently asked questions
What are the key differences between the 5CEFA5U19I7N and the 5CEFA2F23I7?
The 5CEFA5U19I7N is a Cyclone V E FPGA with 77,000 logic elements (LEs) in a UBGA-484 package, while the 5CEFA2F23I7 is a Cyclone V E FPGA with 25,000 LEs in an FBGA-484 package. The 5CEFA5U19I7N offers higher logic density, whereas the 5CEFA2F23I7 provides a smaller logic capacity in a different 484-pin package variant.
Are the 5CEFA5U19I7N and 5CEFA2F23I7 pin-compatible?
No. The 5CEFA5U19I7N uses a UBGA-484 package and the 5CEFA2F23I7 uses an FBGA-484 package. Although both have 484 pins, the package types differ, and pin assignments and PCB land patterns are not interchangeable without verification against the respective datasheets.
Can the 5CEFA2F23I7 be used as a direct substitute for the 5CEFA5U19I7N?
No. The 5CEFA2F23I7 has 25,000 LEs versus 77,000 LEs in the 5CEFA5U19I7N, and the package types differ (FBGA-484 vs UBGA-484). A direct substitution would require validating logic capacity, pinout, and PCB layout against the target design.
What is the operating temperature range for both the 5CEFA5U19I7N and 5CEFA2F23I7?
Both devices are specified with the I7 speed grade and industrial temperature range, typically -40°C to 100°C junction temperature (TJ). Designers should confirm the exact thermal limits in the respective Intel Cyclone V device datasheets.
Do the 5CEFA5U19I7N and 5CEFA2F23I7 belong to the same FPGA family?
Yes. Both are Intel Cyclone V E FPGAs, sharing the same architecture, transceiver options, and IP support, but they differ in logic density and package configuration.
Which device has more embedded memory and multiplier resources?
The 5CEFA5U19I7N, with 77,000 LEs, generally provides more embedded memory blocks and variable-precision DSP blocks than the 5CEFA2F23I7, which has 25,000 LEs. Exact resource counts should be verified in the Intel Cyclone V device handbook.
Are the configuration and power supply requirements the same for both FPGAs?
Both devices use standard Cyclone V configuration schemes (e.g., active serial, passive serial, JTAG) and similar core and I/O voltage rails. However, actual power consumption and decoupling requirements differ due to logic density and package thermal characteristics, so the respective datasheets and power playbooks must be consulted.
