Altera Agilex 7 Ordering Codes and Replacement Guide

An Agilex 7 orderable part number is a hardware configuration, not a long name for the logic density. The official syntax example AGIC040R39A2E2V separates the family, series, fabric features, density, package, tile speed, temperature, core speed and power implementation. An optional suffix can further distinguish a production build, engineering sample or special option.

The safest way to read the example is AG | I | C | 040 | R39A | 2 | E | 2 | V | optional suffix. The two `2` fields are not duplicates: the first is the transceiver-tile speed grade and the second is the FPGA core speed grade.

Decode AGIC040R39A2E2V field by field #

This ordering sequence matters because a search for `AGI040` returns only a family-and-density class. It does not specify a board-compatible device.

Series and fabric specification are architectural fields #

The series letter identifies F-Series, I-Series or M-Series. These series target different combinations of general FPGA performance, high-performance interfaces and memory-intensive systems. A series change is therefore not comparable to buying a wider temperature grade; it can change the available tile types, hard IP, memory subsystem and package plan.

The fabric specification follows the series. In the documented A-H table, the code indicates combinations of hard processor system, cryptographic capability and HBM2E capacity. For example, C and D identify cryptographic-block configurations for supported F- and I-Series densities, while the M-Series E-H codes distinguish HPS presence and 16 GB or 32 GB HBM2E options.

Do not infer a reusable meaning for C outside this Agilex 7 table. Confirm the exact combination against the current product table because not every fabric code is available for every series, density and package.

Density is not a complete resource promise #

The `040` density code identifies the device member, but usable resources still depend on the exact series and package. Procurement should verify the orderable OPN in the current Altera product table, then confirm the resources used by the released Quartus project.

A candidate with a higher density is not automatically a drop-in replacement. Fitting may change, pin availability can differ, and the package migration window may impose restrictions. Treat density migration as an engineering project even when the package code appears unchanged.

Package code is the physical compatibility gate #

In the official example, `R39A` identifies a 3948A package option. Other R-codes correspond to different package sizes, ball counts and transceiver-tile combinations. The same leading `R` does not establish a common footprint.

For a shortage substitution, require all of the following before describing a candidate as pin-compatible:

1. the same required package footprint and ball map; 2. an official package migration path for both exact devices; 3. compatible power, configuration and dedicated-pin requirements; 4. compatible GPIO, transceiver and external-memory assignments; 5. a successful Quartus migration, fit and timing review.

Altera states that Agilex 7 supports vertical, horizontal and conditional migration, but the terms describe controlled migration paths, not universal pin-to-pin compatibility. The Quartus Pin Migration Window and the family package documentation remain mandatory checks.

Tile speed and core speed must be checked separately #

The tile-speed field uses grades 1, 2 and 3, with 1 documented as fastest. The later core-speed field covers the FPGA fabric, with grade 1 fastest and additional grades through 4 in the decoder.

Changing either field requires technical review. A faster tile grade may support the required transceiver performance, but it does not prove that the core-speed, power and package combination is approved. A faster core grade does not compensate for an unsuitable transceiver tile. Quote and compare both fields independently.

Temperature and power are not harmless suffix changes #

The decoder lists E for extended junction temperature from 0°C to 100°C and I for industrial from -40°C to 100°C. An industrial candidate can cover a wider lower-temperature range, but it still needs qualification approval and confirmation that the complete OPN exists in the required package and speed combination.

Power codes distinguish SmartVID and fixed-voltage implementations. The documented set includes V for standard SmartVID, E for lower-power SmartVID, X for lowest-power SmartVID and F for fixed voltage. Changing this field can affect regulator control, voltage assumptions, power estimates and device selection in Quartus. It is not an inventory-only substitution.

Production and engineering suffixes #

The optional suffix must remain attached to the OPN. The decoder distinguishes a blank production build, documented B and C production variants, `R<n>` engineering samples, an `FP` option limited to specified devices, and custom suffixes where applicable.

Never substitute an engineering sample for a production device based only on matching characters before the suffix. Confirm silicon revision, known-issue coverage, qualification status and customer approval. For B or C production variants, verify the feature statement in the current decoder rather than assuming the letter means a generic revision.

Controlled alternate-screening workflow #

When the approved Agilex 7 OPN is unavailable, screen candidates in this order:

1. preserve the complete approved OPN and suffix; 2. match series and fabric specification; 3. match the package code and verify official migration documentation; 4. match density and required resources; 5. check tile speed and core speed independently; 6. confirm temperature and power implementation; 7. select the candidate OPN in Quartus and rerun fit, timing, transceiver and power checks; 8. confirm production status, marking, date/lot code, packing and traceability; 9. compare price, MOQ and lead time only after technical screening.

An alternate may be electrically better in one grade and still be unusable because its package, fabric specification or power option differs.

RFQ checklist #

Conclusion #

The complete Agilex 7 OPN is the purchasing unit. In AGIC040R39A2E2V, the I-Series and C fabric code define architecture, R39A defines the physical package, the two speed fields cover different performance domains, and E/V define environmental and power conditions.

During a shortage, preserve series, fabric and package first. Treat density, speed, temperature and power changes as controlled candidates, then verify them in current Altera documentation and the released Quartus project before approving a replacement.
