Replacement verdict
Not a drop-in replacement
The 5CEFA4F23I7N and 5CEFA2U19A7N are not drop-in replacements for each other. They differ in logic density, package footprint, and I/O pin count, and they operate under different temperature grades. The 5CEFA4F23I7N offers higher logic capacity and more user I/O in a larger FBGA package with industrial temperature support, while the 5CEFA2U19A7N provides lower density and fewer I/O in a smaller UBGA package with automotive temperature qualification. A direct substitution would require board redesign and revalidation.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA4F23I7N | 5CEFA2U19A7N | Why it matters |
|---|---|---|---|
| Family / Series | Cyclone V E | Cyclone V E | Same FPGA family ensures toolchain, IP, and pinout compatibility for migration. |
| Logic Elements (LE) | 49,000 | 25,000 | Determines available logic capacity; a smaller device may not fit the same design. |
| Total RAM Bits | 3,080,000 | 1,536,000 | On-chip memory affects buffering, FIFO depth, and whether a design fits without external RAM. |
| Number of I/Os | 224 | 224 | I/O count must match board routing and peripheral requirements. |
| Package / Case | 484-FBGA (23x23) | 484-UBGA (19x19) | Different package footprint and ballout prevent direct drop-in replacement on the same PCB. |
| Operating Temperature | -40°C to 100°C (TJ) | -40°C to 100°C (TJ) | Industrial temperature range is required for reliable operation in harsh environments. |
| Supply Voltage | 1.07V to 1.13V core | 1.07V to 1.13V core | Core voltage must match power supply design and sequencing requirements. |
| Transceiver Count | 0 | 0 | Absence of high-speed transceivers limits use to general logic and I/O applications. |
| Speed Grade | 7 (fastest) | 7 (fastest) | Speed grade affects maximum clock frequency and timing closure margin. |

Frequently asked questions
What are the key differences between the 5CEFA4F23I7N and the 5CEFA2U19A7N?
The 5CEFA4F23I7N is a Cyclone V FPGA with 49,000 logic elements, 308 embedded multipliers, and 3,880 Kbits of embedded memory in a 484-pin FBGA package. The 5CEFA2U19A7N is a Cyclone V FPGA with 25,000 logic elements, 150 embedded multipliers, and 1,880 Kbits of embedded memory in a 484-pin UBGA package. Both operate at a core voltage of 1.1 V and are rated for industrial temperature range (I7 and A7 speed grades).
Are the 5CEFA4F23I7N and 5CEFA2U19A7N pin-to-pin compatible?
No. The 5CEFA4F23I7N uses a 484-pin FBGA package, while the 5CEFA2U19A7N uses a 484-pin UBGA package. Although both have 484 pins, the package types differ, and the pinout assignments are not identical. They cannot be used as direct drop-in replacements without verifying pin functions and PCB layout compatibility.
Can the 5CEFA2U19A7N be used as a substitute for the 5CEFA4F23I7N in an existing design?
No, not directly. The 5CEFA2U19A7N has fewer logic elements (25,000 vs 49,000), fewer embedded multipliers (150 vs 308), and less embedded memory (1,880 Kbits vs 3,880 Kbits). Additionally, the package type differs (UBGA vs FBGA). A redesign would be required to accommodate the reduced resources and different footprint.
What are the operating temperature ranges for these two FPGAs?
Both the 5CEFA4F23I7N and 5CEFA2U19A7N are specified for industrial temperature range operation, typically -40°C to +100°C junction temperature (TJ). The I7 and A7 suffixes indicate industrial-grade speed grades. Always confirm the exact temperature specifications in the respective Intel Cyclone V device datasheet.
Do both devices support the same configuration and transceiver options?
No. The 5CEFA4F23I7N and 5CEFA2U19A7N belong to different Cyclone V variants. The 5CEFA4F23I7N is a Cyclone V E FPGA with 6 transceivers, while the 5CEFA2U19A7N is a Cyclone V E FPGA with 3 transceivers. Configuration schemes and transceiver count differ, so they are not interchangeable in transceiver-dependent designs.
What is the core voltage and typical power consumption difference between these two FPGAs?
Both devices use a 1.1 V core voltage. However, the 5CEFA4F23I7N, with roughly twice the logic density and memory, typically consumes more static and dynamic power than the 5CEFA2U19A7N. Exact power figures depend on design utilization and must be calculated using Intel's Early Power Estimator or PowerPlay tools.
Are these FPGAs RoHS compliant and lead-free?
Yes. Both the 5CEFA4F23I7N and 5CEFA2U19A7N are offered in RoHS-compliant, lead-free packages as standard from Intel and authorized distributors. Verify the specific ordering code and packaging suffix on the manufacturer datasheet to confirm compliance for your production requirements.
