Replacement verdict
Compatible functional replacement candidate
The 10M40DCF672C8G and 10M40DAF672I7G are both Intel (Altera) MAX 10 field-programmable gate arrays sharing the same 40,000 logic element density, 672-pin FineLine BGA package, and core architecture, making them functionally interchangeable at the device level. The primary distinction lies in their speed grade and operating temperature range: the C8G variant is a commercial-grade device with speed grade 8, while the I7G variant is an industrial-grade device with speed grade 7. Designers must validate timing closure and thermal margins when substituting between these grades, as the industrial variant offers a wider temperature range but a different speed characterization. With matching logic density, package, and I/O count, this pair represents a viable functional replacement candidate subject to timing and environmental validation.

Frequently asked questions
What are the key differences between the 10M40DCF672C8G and the 10M40DAF672I7G?
The primary differences are operating temperature range, speed grade, and package option. The 10M40DCF672C8G is specified for commercial temperature range (0°C to 85°C junction) with speed grade 8, while the 10M40DAF672I7G is specified for industrial temperature range (-40°C to 100°C junction) with speed grade 7. Both are Intel (Altera) MAX 10 FPGA devices in the 672-pin FBGA package with 40,000 logic elements.
Are the 10M40DCF672C8G and 10M40DAF672I7G pin-compatible?
Yes. Both devices are offered in the same 672-pin FineLine BGA (FBGA) package with identical pinouts as defined by the Intel MAX 10 device family. The package designator "F672" is common to both ordering codes, so the physical footprint and pin assignments are the same.
Can the 10M40DCF672C8G be used as a direct drop-in replacement for the 10M40DAF672I7G?
Not unconditionally. Although both are 40,000-logic-element MAX 10 FPGAs in the same 672-pin FBGA package, the 10M40DAF672I7G is rated for the industrial temperature range and a faster speed grade (7) than the 10M40DCF672C8G (commercial temperature range, speed grade 8). A replacement is only valid if the target application operates within the commercial temperature range and the timing closure is re-verified for speed grade 8.
What is the logic density of the 10M40DCF672C8G and 10M40DAF672I7G?
Both devices provide 40,000 logic elements (LEs), which is indicated by the "40" in the 10M40 prefix. They belong to the Intel MAX 10 family of non-volatile FPGAs featuring integrated flash configuration memory.
What temperature range does each device support?
The 10M40DCF672C8G supports the commercial temperature range, typically 0°C to 85°C junction temperature (TJ). The 10M40DAF672I7G supports the industrial temperature range, typically -40°C to 100°C junction temperature (TJ). The "C" and "I" in the ordering codes denote commercial and industrial grades respectively.
What does the speed grade difference between these two parts mean for design timing?
The 10M40DAF672I7G has speed grade 7, while the 10M40DCF672C8G has speed grade 8. In Intel FPGA ordering codes, a lower speed grade number indicates faster performance. Therefore, the speed grade 7 device supports shorter propagation delays and higher maximum operating frequencies than the speed grade 8 device. Timing analysis must be re-run if substituting one for the other.
Do both devices support the same configuration and flash features of the MAX 10 family?
Yes. Both the 10M40DCF672C8G and 10M40DAF672I7G are MAX 10 devices and include the family's integrated features such as on-chip flash configuration memory, instant-on capability, and support for dual configuration images. Feature availability is determined by the MAX 10 device family and the specific device density, not by the temperature grade or speed grade suffix.
Which device should be selected for an industrial-temperature application?
The 10M40DAF672I7G should be selected for industrial-temperature applications because it is rated for the industrial temperature range (-40°C to 100°C TJ). The 10M40DCF672C8G is only rated for the commercial temperature range and is not specified for operation below 0°C or above 85°C junction temperature.
