Replacement verdict
Compatible functional replacement candidate
The 10AX048H3F34E2SG and 10AX032H2F34E2SG are both Intel Arria 10 GX FPGA devices in the same 1152-pin FBGA package with identical I/O and transceiver counts, making them functionally interchangeable at the board level. The primary distinction is logic density, with the 10AX048H3F34E2SG offering 48,000 logic elements versus 32,000 in the 10AX032H2F34E2SG, alongside a higher-speed grade. Designers must verify that the target design's resource utilization fits within the smaller device and that timing closure is achievable at the required performance level before committing to the lower-density variant as a substitute.

Key electrical and mechanical differences between the two devices
| Parameter | 10AX048H3F34E2SG | 10AX032H2F34E2SG | Why it matters |
|---|---|---|---|
| Logic Elements (LE) | 480,000 | 320,000 | Logic capacity determines how much custom digital logic can be implemented; a smaller device may not fit the same design. |
| Adaptive Logic Modules (ALM) | 183,590 | 122,400 | ALMs are the fundamental logic building blocks; fewer ALMs directly reduce the achievable logic density. |
| Total Embedded Memory | 28,080 Kbit | 18,720 Kbit | On-chip memory affects buffering, FIFO depth, and data storage capability within the FPGA fabric. |
| Variable-Precision DSP Blocks | 1,368 | 912 | DSP blocks accelerate multiply-accumulate operations; fewer blocks limit signal processing throughput. |
| Maximum User I/O Pins | 492 | 492 | I/O count determines how many external interfaces and peripherals can be connected simultaneously. |
| Transceiver Count | 24 | 24 | High-speed serial transceivers enable protocols such as PCIe, Ethernet, and JESD204; matching counts preserve interface capability. |
| Package | FBGA-1152 | FBGA-1152 | Package compatibility ensures the same PCB footprint and assembly process can be reused. |
| Speed Grade | 3 (High Performance) | 2 (Mid Performance) | Speed grade affects maximum operating frequency and timing closure; a slower grade may not meet original performance targets. |
| Operating Temperature Range | 0°C to 100°C (Commercial) | 0°C to 100°C (Commercial) | Temperature range must match the target environment to ensure reliable operation and thermal compliance. |

Frequently asked questions
What are the primary differences between the 10AX048H3F34E2SG and the 10AX032H2F34E2SG?
The 10AX048H3F34E2SG is an Intel Arria 10 GX FPGA with 480,000 logic elements, while the 10AX032H2F34E2SG is an Arria 10 GX FPGA with 320,000 logic elements. Both use the same 1152-pin FBGA package (F34) and are specified for the commercial temperature grade (E2), but they differ in logic density and speed grade (H3 vs H2).
Are the 10AX048H3F34E2SG and 10AX032H2F34E2SG pin-compatible?
Yes. Both devices are offered in the same F34 package, which is a 1152-pin FineLine BGA (FBGA) with a 1.0 mm pitch. Intel documents the F34 package as a common package option across multiple Arria 10 GX density variants, so the pinout and PCB footprint are identical.
Can the 10AX032H2F34E2SG be used as a drop-in replacement for the 10AX048H3F34E2SG?
No, not as a direct drop-in replacement. Although the package is identical, the 10AX032H2F34E2SG has fewer logic elements (320K vs 480K) and a different speed grade (H2 vs H3). A design that fully utilizes the 10AX048H3F34E2SG resources or relies on its higher speed grade may not fit or meet timing in the smaller, slower device without redesign and recompilation.
What is the difference in speed grade between the H3 and H2 variants?
In Intel Arria 10 nomenclature, the speed grade is indicated by the letter and number following the density code. The H3 suffix on the 10AX048H3F34E2SG denotes a faster speed grade than the H2 suffix on the 10AX032H2F34E2SG. The higher speed grade generally supports higher core and transceiver performance, but exact timing specifications must be verified in the respective device datasheets.
Do both devices support the same transceiver speeds and protocols?
Both are Arria 10 GX devices and support the same transceiver protocol IP and hard IP blocks, but the maximum achievable transceiver data rate depends on the specific speed grade. The H3 speed grade of the 10AX048H3F34E2SG may support higher maximum transceiver rates than the H2 speed grade of the 10AX032H2F34E2SG. Designers must confirm the supported rates in the Arria 10 device datasheet for each speed grade.
Are the power supply requirements the same for both FPGAs?
Both devices belong to the Intel Arria 10 GX family and use the same power supply rails and nominal voltages as defined in the Arria 10 device datasheet. However, actual current consumption and power dissipation differ because the 10AX048H3F34E2SG has more logic resources and a faster speed grade than the 10AX032H2F34E2SG. Power estimation should be performed separately for each device using Intel's Early Power Estimator or PowerPlay tools.
Which device is more suitable for a new design with moderate logic requirements?
The 10AX032H2F34E2SG may be more suitable when logic utilization is moderate and the higher speed grade of the 10AX048H3F34E2SG is not required, since it can reduce cost and power. However, the final choice must be based on verified resource utilization, timing closure, and transceiver requirements for the specific application.
Do both devices share the same configuration and boot options?
Yes. Both the 10AX048H3F34E2SG and 10AX032H2F34E2SG are Intel Arria 10 GX FPGAs and support the same configuration schemes, including active serial, passive serial, JTAG, and configuration via external controllers, as documented in the Arria 10 configuration user guide. The configuration bitstream size differs according to device density.
