5CEFA5U19I7N vs 5CEFA7M15I7N

The 5CEFA5U19I7N and 5CEFA7M15I7N are both Intel (formerly Altera) Cyclone V FPGAs in the same speed grade (I7) and temperature grade (industrial), but they differ in logic density, package, and I/O count. The 5CEFA5U19I7N belongs to the A5 density variant with approximately 77,000 logic elements (LEs) in a UBGA-484 package, while the 5CEFA7M15I7N belongs to the A7 density variant with approximately 149,500 LEs in an MBGA-484 package. The higher-density A7 device offers more embedded memory, more multipliers, and more user I/O than the A5 device.

No. Although both devices use a 484-ball package, the 5CEFA5U19I7N uses a UBGA-484 (U19) package while the 5CEFA7M15I7N uses an MBGA-484 (M15) package. These are distinct package outlines with different ball maps and thermal/electrical characteristics. A direct drop-in replacement is not possible without verifying pin assignments, PCB land patterns, and signal integrity against the respective Intel Cyclone V device pin-out files.

Not directly. The 5CEFA7M15I7N has a different package (MBGA-484 vs UBGA-484), a different logic density (A7 vs A5), and a different ball map. Substitution would require a PCB redesign, re-verification of pin assignments, power delivery, and configuration scheme. Additionally, the A7 device consumes more power and may require different decoupling and thermal management. Intel documentation must be consulted before any substitution.

The 5CEFA5U19I7N (Cyclone V A5) provides approximately 77,000 logic elements (LEs). The 5CEFA7M15I7N (Cyclone V A7) provides approximately 149,500 LEs. These values are based on Intel Cyclone V device family datasheets and represent the adaptive logic module (ALM) count converted to equivalent LEs.

Both the 5CEFA5U19I7N and 5CEFA7M15I7N are Cyclone V FPGAs and support the same configuration schemes, including active serial (AS), passive serial (PS), fast passive parallel (FPP), and JTAG configuration. However, the configuration bitstream size differs between the A5 and A7 density variants, so the configuration memory size and configuration time will differ. The specific configuration scheme must be validated against the Intel Cyclone V configuration user guide for each density.

Both the 5CEFA5U19I7N and 5CEFA7M15I7N carry the "I7" suffix, indicating industrial temperature grade and speed grade 7. The industrial temperature grade for Cyclone V devices typically supports a junction temperature range of -40°C to +100°C (Tj). The exact operating conditions should be confirmed in the Intel Cyclone V device datasheet, as thermal performance depends on package, power dissipation, and airflow.

The 5CEFA7M15I7N generally offers more user I/O pins than the 5CEFA5U19I7N because the A7 density variant provides a higher logic-to-I/O ratio and the MBGA-484 package supports a different I/O bank arrangement. The exact user I/O count for each device must be verified from the Intel Cyclone V device pin-out files, as the available I/O depends on the package and the number of dedicated transceiver or configuration pins.

Intel Cyclone V FPGAs, including the 5CEFA5U19I7N and 5CEFA7M15I7N, are offered in RoHS-compliant, lead-free package options. The "N" suffix in both part numbers typically indicates lead-free (Pb-free) construction. However, RoHS compliance and lead-free status should be confirmed through the Intel product material declaration or the distributor's environmental documentation for the specific ordering code.
