Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA7F23I7N | 5CEFA2U19C6N | 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) | 149,500 | 25,000 | LE count determines available logic capacity; a large mismatch prevents direct functional substitution. |
| Total RAM Bits | 7,880,448 | 1,536,000 | Embedded memory capacity affects buffering, FIFOs, and data-path implementations. |
| Number of I/Os | 480 | 224 | I/O count limits peripheral and interface expansion; fewer pins restrict system connectivity. |
| Package / Case | FBGA-484 | UBGA-484 | Package type and footprint must match for PCB layout compatibility. |
| Operating Temperature Range | -40°C to +100°C (Industrial) | 0°C to +85°C (Commercial) | Temperature grade determines suitability for industrial versus commercial environments. |
| Speed Grade | 7 (Fastest) | 6 (Faster) | Speed grade affects maximum operating frequency and timing closure margins. |
| Supply Voltage - Core | 1.1 V | 1.1 V | Core voltage must match the board power design for correct operation. |

Frequently asked questions
What are the key differences between the 5CEFA7F23I7N and the 5CEFA2U19C6N?
The 5CEFA7F23I7N is a Cyclone V FPGA with 149,500 logic elements (LEs) in a 484-pin FBGA package, while the 5CEFA2U19C6N is a Cyclone V FPGA with 25,000 LEs in a 484-pin UBGA package. The 5CEFA7F23I7N offers significantly higher logic density, whereas the 5CEFA2U19C6N targets lower-cost, lower-power applications.
Are the 5CEFA7F23I7N and 5CEFA2U19C6N pin-to-pin compatible?
No. The 5CEFA7F23I7N uses a 484-pin FBGA package (F23), and the 5CEFA2U19C6N uses a 484-pin UBGA package (U19). Although both have 484 pins, the package types, ball maps, and PCB land patterns differ, so they are not drop-in replacements.
What are the operating temperature ranges for these two devices?
The 5CEFA7F23I7N has an industrial temperature grade (I7), typically specified for -40°C to 100°C junction temperature. The 5CEFA2U19C6N has a commercial temperature grade (C6), typically specified for 0°C to 85°C junction temperature. The industrial-grade part is suitable for harsher environments.
Can the 5CEFA2U19C6N be used as a substitute for the 5CEFA7F23I7N in an existing design?
No, not directly. The 5CEFA2U19C6N has only 25,000 LEs versus 149,500 LEs in the 5CEFA7F23I7N, and the package type and temperature grade differ. A redesign would be required to accommodate the lower logic density, different pinout, and commercial temperature range.
What are the typical power supply requirements for these Cyclone V FPGAs?
Both devices require a core voltage (VCC) of 1.1 V, auxiliary voltages, and I/O voltages that depend on the selected I/O standards. Exact supply rails and tolerances must be verified from the respective Intel Cyclone V device datasheets, as they vary by speed grade and configuration.
Which device is better suited for high-logic-density applications?
The 5CEFA7F23I7N is better suited for high-logic-density applications because it provides 149,500 LEs, significantly more than the 25,000 LEs of the 5CEFA2U19C6N. The 5CEFA7F23I7N also supports more embedded memory and DSP blocks, making it appropriate for complex processing tasks.
Do both devices support the same configuration and transceiver options?
No. The 5CEFA7F23I7N and 5CEFA2U19C6N belong to different Cyclone V variants with different transceiver counts, memory capacities, and configuration schemes. Designers must consult the specific device datasheets and pin-out files to confirm supported features for each part number.
