Replacement verdict
Compatible functional replacement candidate
The 10M16DCU324A7G is a viable functional replacement candidate for the 10M16DAU324C8G, sharing the same Intel MAX 10 device family, 16,000 logic elements, and 324-ball UBGA footprint. The primary distinction is the speed grade, with the DCU variant offering a faster maximum operating frequency. Designers must validate timing closure and power dissipation at the target clock rate before committing to this substitution.

Frequently asked questions
What are the 10M16DAU324C8G and 10M16DCU324A7G devices?
Both are Intel (formerly Altera) MAX 10 family field-programmable gate arrays (FPGAs) in a 324-pin Ultra FineLine BGA (UBGA) package. They share the same 16,000 logic element (LE) density and belong to the same MAX 10 10M16 device series, but differ in speed grade and operating temperature grade.
What is the difference between the C8 and A7 suffixes on these two part numbers?
The suffix encodes speed grade and temperature grade. The 10M16DAU324C8G is specified with a commercial temperature grade and speed grade 8, while the 10M16DCU324A7G is specified with an automotive temperature grade and speed grade 7. The "D" in both part numbers denotes the dual-supply (1.2 V core) MAX 10 variant, and "G" indicates RoHS-compliant lead-free packaging.
Are the 10M16DAU324C8G and 10M16DCU324A7G pin-compatible?
Yes. Both devices use the same 324-pin UBGA package with the same pinout for the 10M16 device density, so they are footprint- and pin-compatible. However, pin compatibility does not guarantee functional interchangeability, because speed grade and temperature grade differ.
Can the 10M16DAU324C8G be used as a drop-in replacement for the 10M16DCU324A7G?
Not unconditionally. Although the package and pinout match, the 10M16DCU324A7G is rated for the automotive temperature range and a faster speed grade (7) than the 10M16DAU324C8G (commercial grade, speed grade 8). A replacement is only valid if the target design's timing, power, and environmental requirements are re-verified against the Intel MAX 10 datasheet and the specific device ordering information.
Do both devices support the same configuration and memory features?
Yes. As members of the same MAX 10 10M16 device family, both integrate the same core features, including on-chip flash configuration memory, analog-to-digital converter (ADC) blocks, and internal configuration. Feature availability is determined by the device family and density, not by the speed or temperature grade suffix.
Which device should be selected for automotive applications?
The 10M16DCU324A7G, because its "A" suffix denotes the automotive temperature grade, making it suitable for applications requiring extended temperature operation. The 10M16DAU324C8G carries a commercial temperature grade and is intended for standard commercial environments.
Does the speed grade difference affect timing closure?
Yes. Speed grade 7 (10M16DCU324A7G) provides faster maximum operating frequencies and shorter propagation delays than speed grade 8 (10M16DAU324C8G). Designs must be re-timed and re-analyzed in the Intel Quartus Prime software when migrating between these speed grades to confirm timing closure.
Are both part numbers RoHS compliant?
Yes. The trailing "G" in both part numbers indicates RoHS-compliant, lead-free (Pb-free) packaging, consistent with Intel MAX 10 ordering information for these device options.
