Replacement verdict
Compatible functional replacement candidate
The 10M25DCF484C8G and 10M25DAF484C7G are both Intel MAX 10 FPGA devices sharing the same 25,000-logic-element density and 484-ball FBGA package, making them functionally interchangeable in many designs. However, they differ in speed grade and operating temperature range, so the 10M25DAF484C7G should be validated against the target application's timing and thermal requirements before being used as a drop-in substitute for the 10M25DCF484C8G.

Frequently asked questions
What are the 10M25DCF484C8G and 10M25DAF484C7G devices?
Both are Intel (formerly Altera) MAX 10 field-programmable gate arrays (FPGAs) in the 10M25 density tier, featuring 25,000 logic elements (LEs), non-volatile integrated flash configuration, and a 484-pin FineLine BGA (FBGA) package. The 10M25DCF484C8G is specified with a commercial temperature grade and speed grade 8, while the 10M25DAF484C7G is specified with an automotive temperature grade and speed grade 7.
What is the difference between the 10M25DCF484C8G and the 10M25DAF484C7G?
The primary differences are the temperature grade and speed grade. The 10M25DCF484C8G uses the "C" commercial temperature grade (typically 0°C to 85°C junction) with speed grade 8, whereas the 10M25DAF484C7G uses the "A" automotive temperature grade (typically -40°C to 125°C junction) with speed grade 7. Both share the same 10M25 die, 484-pin FBGA package, and MAX 10 feature set.
Are the 10M25DCF484C8G and 10M25DAF484C7G pin-compatible?
Yes. Both devices are offered in the same 484-pin FineLine BGA (FBGA) package with the same pinout for the 10M25 density, so the physical footprint and pin assignments are identical. However, pin-compatibility does not guarantee functional interchangeability without validating timing, temperature, and speed-grade requirements.
Can the 10M25DCF484C8G and 10M25DAF484C7G be used interchangeably in a design?
Not automatically. Although they share the same package and die, the different speed grades (8 vs. 7) and temperature grades (commercial vs. automotive) affect timing closure, maximum operating frequency, and environmental limits. A design must be re-timed and validated against the target device's speed grade and temperature range before substitution.
What is the difference between speed grade 7 and speed grade 8 on these MAX 10 devices?
In Intel MAX 10 ordering codes, a lower speed-grade number indicates a faster device. Speed grade 7 (10M25DAF484C7G) provides faster maximum operating frequencies and tighter timing than speed grade 8 (10M25DCF484C8G). Designs closed on speed grade 8 may not meet timing if migrated to speed grade 7 without re-analysis, and vice versa.
What temperature ranges do the 10M25DCF484C8G and 10M25DAF484C7G support?
The 10M25DCF484C8G carries the commercial "C" temperature grade, and the 10M25DAF484C7G carries the automotive "A" temperature grade. The automotive-grade device is intended for applications requiring extended temperature operation and automotive qualification, while the commercial-grade device targets standard commercial environments. Exact junction temperature limits should be confirmed in the Intel MAX 10 device datasheet.
Do both devices support non-volatile configuration and instant-on operation?
Yes. Both the 10M25DCF484C8G and 10M25DAF484C7G are MAX 10 FPGAs, which integrate non-volatile flash configuration memory. This enables instant-on operation and single-chip configuration without an external configuration device, a feature common to the entire MAX 10 family.
Which device should be selected for an automotive application?
The 10M25DAF484C7G is the appropriate choice for automotive applications because its "A" temperature grade and automotive qualification align with under-hood or extended-temperature requirements. The 10M25DCF484C8G, with its commercial temperature grade, is generally not intended for automotive-qualified designs.
