Replacement verdict
Compatible functional replacement candidate
The 5CEFA5U19I7N and 5CEFA9U19A7N are both Intel Cyclone V FPGA devices in the same UBGA-484 package, sharing identical I/O, voltage, and temperature specifications. The primary distinction is logic density, with the 5CEFA9U19A7N offering approximately twice the adaptive logic modules and embedded memory. This makes it a viable functional upgrade candidate where additional FPGA resources are required, provided the board design accommodates the higher power envelope and the application can be recompiled for the larger device.

Key electrical and mechanical differences between the two devices
| Parameter | 5CEFA5U19I7N | 5CEFA9U19A7N | Why it matters |
|---|---|---|---|
| Logic Elements (LE) | 77,000 | 301,000 | Logic element count determines the amount of programmable logic available for implementing custom digital functions; a large difference means the two devices are not functionally interchangeable for complex designs. |
| Total Embedded Memory | 4,460 kbit | 13,917 kbit | On-chip memory capacity affects the ability to store data, buffers, and look-up tables; designs requiring large memory blocks cannot be migrated to the smaller device. |
| 18x18 Multipliers | 150 | 684 | Dedicated multipliers are essential for DSP and arithmetic-intensive applications; the significant difference limits substitutability in signal-processing designs. |
| Maximum User I/O | 224 | 224 | User I/O count determines how many external signals the device can interface with; matching counts support pin-compatible migration for peripheral connections. |
| PLLs | 6 | 8 | Phase-locked loops generate and synchronize clock domains; fewer PLLs may restrict clocking flexibility in complex multi-clock systems. |
| Package | 484-pin UBGA | 484-pin UBGA | Package type and pin count must match for physical board compatibility; identical packages allow the same PCB footprint to be reused. |
| Operating Temperature Range | -40°C to 100°C (Industrial) | -40°C to 125°C (Automotive) | Temperature grade affects reliability in harsh environments; the automotive-grade device supports higher ambient temperatures, which may be required for certain applications. |
| Speed Grade | 7 (Fastest) | 7 (Fastest) | Speed grade determines maximum operating frequency and timing closure; matching grades ensure comparable performance when migrating designs. |
| Supply Voltage (Core) | 1.1 V | 1.1 V | Core voltage must match the board power design; identical values allow the same power supply rail to be used without modification. |

Frequently asked questions
What are the key differences between the 5CEFA5U19I7N and the 5CEFA9U19A7N?
The 5CEFA5U19I7N and 5CEFA9U19A7N are both Intel (formerly Altera) Cyclone V FPGAs in the same 484-pin UBGA (U19) package, but they differ in logic density, speed grade, and temperature grade. The 5CEFA5U19I7N is a Cyclone V E A5 device with 77,000 logic elements (LEs) and is specified for the industrial temperature range with a speed grade of 7. The 5CEFA9U19A7N is a Cyclone V E A9 device with 301,000 LEs and is specified for the automotive temperature range with a speed grade of 7. The A9 variant therefore offers substantially higher logic capacity, while the A5 variant targets lower-density applications.
Are the 5CEFA5U19I7N and 5CEFA9U19A7N pin-compatible?
Both devices are offered in the same 484-pin UBGA (U19) package, and Intel documents the Cyclone V E A5 and A9 devices as sharing the same package footprint for a given package option. However, pin-compatibility must be verified against the specific device pin-out files and the target board design, because I/O bank assignments, transceiver availability, and dedicated pin functions can differ between density variants. Intel recommends confirming compatibility using the official pin-out files and the Quartus Prime software for the exact device and package combination.
Can the 5CEFA5U19I7N be used as a drop-in replacement for the 5CEFA9U19A7N?
No. Although both are Cyclone V E devices in the same U19 package, the 5CEFA9U19A7N has significantly more logic elements (301,000 vs. 77,000), different internal resources, and a different temperature grade (automotive vs. industrial). A drop-in replacement would require recompiling the FPGA design for the target device, re-validating timing, power, and I/O assignments, and confirming that the board-level thermal and electrical requirements are met. Intel does not support direct substitution without a full design recompilation and validation.
What temperature grades do the 5CEFA5U19I7N and 5CEFA9U19A7N support?
The 5CEFA5U19I7N is specified for the industrial temperature grade, which Intel defines for Cyclone V devices as operating junction temperature (TJ) of -40°C to +100°C. The 5CEFA9U19A7N is specified for the automotive temperature grade, which Intel defines for Cyclone V devices as operating junction temperature (TJ) of -40°C to +125°C. The automotive-grade device is therefore suitable for higher-temperature environments, while the industrial-grade device is intended for standard industrial applications.
What logic density does each device provide?
The 5CEFA5U19I7N provides 77,000 logic elements (LEs) as part of the Cyclone V E A5 density variant. The 5CEFA9U19A7N provides 301,000 logic elements (LEs) as part of the Cyclone V E A9 density variant. Both devices also include embedded memory blocks, variable-precision DSP blocks, and configurable I/O, but the A9 device offers substantially more of these resources due to its higher logic density. Designers should consult the Cyclone V Device Handbook for the complete resource comparison.
Do both devices support the same configuration and transceiver options?
Both the 5CEFA5U19I7N and 5CEFA9U19A7N are Cyclone V E devices, which do not include high-speed transceivers; transceiver-equipped variants are part of the Cyclone V GX and GT families. Configuration options for both devices include active serial (AS), passive serial (PS), fast passive parallel (FPP), and JTAG, as documented in the Cyclone V Device Handbook. The availability of specific configuration schemes and I/O standards should be verified for each density variant using the official device documentation and Quartus Prime software.
Which device is better suited for automotive applications?
The 5CEFA9U19A7N is better suited for automotive applications because it is specified for the automotive temperature grade (TJ of -40°C to +125°C), while the 5CEFA5U19I7N is specified for the industrial temperature grade (TJ of -40°C to +100°C). Automotive applications typically require components qualified to higher temperature ranges and, in many cases, additional automotive qualification standards. Designers should confirm that the specific device ordering code and qualification status meet the target automotive requirements before selection.
What speed grade do the 5CEFA5U19I7N and 5CEFA9U19A7N use?
Both the 5CEFA5U19I7N and the 5CEFA9U19A7N use speed grade 7, as indicated by the "7" in their ordering codes. Speed grade 7 is one of the standard Cyclone V speed grades and affects the maximum operating frequency and timing performance of the device. Because the two devices have different logic densities, their achievable performance for a given design may differ even at the same speed grade, and timing must be re-validated in Quartus Prime for the target device.
