Replacement verdict
Compatible functional replacement candidate
The 5CEFA5U19I7N and 5CEFA7U19C6N are both Intel Cyclone V FPGAs in the same UBGA-484 package with identical I/O count and supply voltage, making them functionally interchangeable in many designs. However, the 5CEFA7U19C6N offers higher logic density and faster speed grade, while the 5CEFA5U19I7N provides a wider industrial temperature range. Designers should validate logic utilization, timing closure, and thermal requirements before substituting.

Frequently asked questions
What are the key differences between the 5CEFA5U19I7N and the 5CEFA7U19C6N?
The 5CEFA5U19I7N and 5CEFA7U19C6N are both Intel (formerly Altera) Cyclone V FPGAs in the same 484-pin UBGA package (U19). The primary differences are logic density, speed grade, and operating temperature range. The 5CEFA5U19I7N belongs to the A5 density variant with approximately 77,000 logic elements (LEs) and is rated for industrial temperature range (I7, typically -40°C to 100°C junction). The 5CEFA7U19C6N belongs to the A7 density variant with approximately 149,500 LEs and is rated for commercial temperature range (C6, typically 0°C to 85°C junction). The A7 device offers roughly twice the logic capacity of the A5, while the A5 device offers a wider industrial temperature range.
Are the 5CEFA5U19I7N and 5CEFA7U19C6N pin-to-pin compatible?
Both devices are offered in the same 484-pin UBGA (U19) package, and Intel documents them under the same package outline. However, pin-to-pin compatibility cannot be assumed solely from the package designator. The A5 and A7 dies have different logic densities and may assign different functions to certain pins, particularly dedicated I/O, transceiver, and configuration pins. A detailed pinout comparison using the respective device pin-out files from Intel is required before considering a direct board-level swap.
Can the 5CEFA7U19C6N be used as a drop-in replacement for the 5CEFA5U19I7N?
No, a drop-in replacement is not supported without design validation. Although both are Cyclone V devices in the same U19 package, they differ in logic density (A5 vs A7), speed grade (7 vs 6), and temperature grade (I vs C). The A7 device has more logic resources and a different floorplan, which affects timing closure, power consumption, and pin assignments. Additionally, the commercial temperature grade of the 5CEFA7U19C6N does not cover the industrial temperature range of the 5CEFA5U19I7N. A full recompilation, timing analysis, and thermal review are mandatory.
What are the logic element counts for the 5CEFA5U19I7N and 5CEFA7U19C6N?
According to Intel Cyclone V device documentation, the 5CEFA5U19I7N (A5 density) contains approximately 77,000 logic elements (LEs). The 5CEFA7U19C6N (A7 density) contains approximately 149,500 LEs. These figures are based on the Cyclone V FPGA family datasheet and reflect the programmable logic capacity available for user designs.
What do the speed grade and temperature grade suffixes indicate for these two parts?
In the part numbers 5CEFA5U19I7N and 5CEFA7U19C6N, the suffix after the package code indicates speed grade and temperature grade. For the 5CEFA5U19I7N, "I7" denotes industrial temperature range (typically -40°C to 100°C junction) and speed grade 7. For the 5CEFA7U19C6N, "C6" denotes commercial temperature range (typically 0°C to 85°C junction) and speed grade 6. Speed grade 6 is faster than speed grade 7 in the Cyclone V family, meaning the 5CEFA7U19C6N has a higher performance rating but a narrower temperature range.
Do both devices support the same configuration and transceiver features?
Both the 5CEFA5U19I7N and 5CEFA7U19C6N are Cyclone V FPGAs and share the same family-level architecture, including support for configuration via active serial, passive serial, JTAG, and other standard methods. However, the number of available transceivers, phase-locked loops (PLLs), and high-speed I/O banks may differ between the A5 and A7 density variants. Designers must consult the specific device datasheet and pin-out files to confirm the exact transceiver count and feature set for each density.
Which device is more suitable for industrial temperature environments?
The 5CEFA5U19I7N is more suitable for industrial temperature environments because its "I7" suffix indicates an industrial temperature grade, typically supporting a junction temperature range of -40°C to 100°C. The 5CEFA7U19C6N carries a "C6" commercial temperature grade, typically rated for 0°C to 85°C junction temperature. If the application requires operation below 0°C or above 85°C, the 5CEFA5U19I7N is the appropriate choice, provided its lower logic density meets the design requirements.
What package type do the 5CEFA5U19I7N and 5CEFA7U19C6N use?
Both the 5CEFA5U19I7N and 5CEFA7U19C6N use the 484-pin UBGA (Ultra FineLine BGA) package, designated by the "U19" code in the part number. This package is a 484-ball fine-pitch BGA with a 0.8 mm ball pitch, as specified in Intel Cyclone V device packaging documentation. The physical package outline is the same for both devices, but the internal die and pin assignments may differ between the A5 and A7 variants.
