Altera Cyclone 10 GX Ordering Codes Guide

A Cyclone 10 GX orderable part number is a sequence of device, package and grade decisions. The official ordering example 10CX220YF780I5GES reads as 10C | X | 220 | Y | F | 780 | I | 5 | G | ES: Cyclone 10 family, GX transceiver variant, 220K logic elements, standard 0.9 V core, FineLine BGA, 780 pins, industrial temperature, fabric speed grade 5, RoHS 6 material and engineering-sample status.

For production purchasing, Altera currently lists OPNs such as 10CX220YU484I5G. That code keeps the same field order but selects the 484-pin Ultra FineLine BGA and has no ES suffix. The complete OPN—not 10CX220 alone—must appear on the RFQ and purchase order.

Decode 10CX220YF780I5GES field by field #

Density and package availability must be read together #

The current Cyclone 10 GX overview lists four product lines: 10CX085, 10CX105, 10CX150 and 10CX220. Their nominal logic-element counts are 85K, 104K, 150K and 220K. Density does not independently define I/O or transceiver capacity because package availability changes the usable resources.

Altera's package plan defines three physical packages:

The 10CX085 is offered in U484 and F672, but not F780. The three larger densities are offered in all three packages. U484 provides 188 GPIO and six transceivers across the product lines. F672 provides more GPIO and up to ten transceivers on 10CX105/150/220, while F780 provides 284 GPIO and twelve transceivers on those same densities. A higher-density die in U484 therefore does not recreate the I/O and transceiver resources of an F780 design.

Package letters and numbers must remain one physical field. Changing F780 to U484 changes package technology, pitch, body size, ball count and pinout. It cannot be called pin-to-pin. Changing F672 to F780 is also a new footprint even though both are 1.0 mm FineLine BGAs.

Temperature, speed and core-voltage fields #

The official decoder defines E as the extended 0°C to 100°C junction range and I as industrial −40°C to 100°C. Moving from E to I widens the low-temperature rating, but it is only a possible engineering alternate when density, voltage, package and all other fields remain supported. Qualification and the customer AVL still control acceptance.

Fabric speed grade 5 is faster than 6 in the official option figure. A grade-5 device may be screened as an alternate for a grade-6 requirement, but only after the released Quartus project is recompiled and timing, transceiver and power results are reviewed. The numeric ordering alone does not authorize procurement substitution.

The Y field identifies the standard 0.9 V core option. It is not packaging or shipment information. Preserve it when comparing quotations and verify the device power tree against the current datasheet and pin-connection guideline.

RoHS and engineering-sample suffixes #

The G field identifies RoHS 6 compliance. It remains part of the production OPN, as shown by Altera's current 10CX220YU484I5G product record. The final ES in the official syntax example is optional and identifies an engineering sample.

That difference is operationally important: 10CX220YF780I5GES is not merely a longer spelling of 10CX220YF780I5G. Engineering samples may have different qualification status or limitations and should not be accepted for a production build without explicit approval. Conversely, an RFQ for a production device should not add ES merely because it appears in the decoder illustration.

Replacement screening and pin-to-pin limits #

Cyclone 10 GX supports documented vertical migration paths, but Altera attaches conditions. To retain full I/O migration within a supported path, the design must restrict I/O and transceiver use to the lowest-resource device in that path. Altera also directs designers to verify compatibility with the Pin Migration View in Quartus Prime Pro Pin Planner.

An alternate may enter engineering review when the family variant, core voltage, package type and package code are unchanged and the proposed density belongs to a supported migration path. A faster speed grade or wider temperature grade can also be considered when the exact density/package combination exists. None of these checks makes the alternate automatically approved.

Reject a claimed drop-in replacement when:

• the package changes among U484, F672 and F780;
• the package code, ball count, body size or pitch differs;
• the design uses more GPIO or transceivers than the smaller migration device provides;
• the core-voltage field changes;
• an engineering-sample suffix is introduced for a production build;
• the candidate is outside the official vertical-migration path;
• Quartus Pin Migration View reports incompatible assignments;
• bank voltage, configuration, transceiver, memory-interface or dedicated-pin requirements differ.

The pin-connection guideline remains necessary even when two devices share one package code. Package equality is a prerequisite, not proof. Pin assignments, I/O-bank use, transceiver channels and dedicated pins must be valid for both exact OPNs.

Procurement checklist #

1. Copy the complete OPN from the released BOM, including G and any optional suffix. 2. Confirm that the decoder is for Cyclone 10 GX, not Cyclone 10 LP. 3. Match density, core voltage, package type, package code and pin count. 4. Confirm body size, pitch, tray media and moisture-handling requirements for the exact product record. 5. Match temperature and speed grades to the qualified Quartus build. 6. Reject ES for production unless the build is explicitly approved for engineering samples. 7. Check the package plan and vertical-migration figure for both densities. 8. Run Quartus Pin Migration View and recompile timing and pin assignments. 9. Put the accepted full OPN on the quotation, PO, incoming inspection record and traceability documents.

Conclusion #

Cyclone 10 GX ordering codes are straightforward only when the physical and grade fields stay attached to the density. In 10CX220YF780I5G, F780 fixes a 780-pin, 29 × 29 mm FineLine BGA footprint, I5 fixes the temperature and speed grades, and G fixes material status. A higher density, faster speed or wider temperature range may qualify for engineering review, but a different package is not pin-to-pin and an ES device is not a production substitute.
