Replacement verdict
Compatible functional replacement candidate
The 10M08DCF256I7G and 10M08DCF256C7G are functionally equivalent Intel MAX 10 FPGA devices sharing identical logic density, package, and I/O configuration; the primary distinction is the industrial versus commercial temperature grade, making the C7G a viable replacement for the I7G only in operating environments that remain within the commercial temperature range.

Frequently asked questions
What is the difference between the 10M08DCF256I7G and the 10M08DCF256C7G?
The primary difference is the operating temperature grade: the 10M08DCF256I7G is an industrial-grade device (I7), while the 10M08DCF256C7G is a commercial-grade device (C7). Both are Intel (formerly Altera) MAX 10 field-programmable gate arrays (FPGAs) with 8,000 logic elements, a 256-ball FineLine BGA (FBGA) package, and speed grade 7. The industrial version supports a wider ambient temperature range, whereas the commercial version is intended for typical office or consumer environments.
Are the 10M08DCF256I7G and 10M08DCF256C7G pin-to-pin compatible?
Yes. Both devices use the same 256-ball FineLine BGA (FBGA) package with identical pinouts, as defined by the Intel MAX 10 device pin-out files. They are physically and electrically pin-to-pin compatible, allowing the same PCB footprint to be used for either temperature grade.
Can the 10M08DCF256C7G be used as a drop-in replacement for the 10M08DCF256I7G?
Not unconditionally. While the package and pinout are identical, the industrial-grade 10M08DCF256I7G is specified for a wider temperature range than the commercial-grade 10M08DCF256C7G. A drop-in replacement is only acceptable if the target application's operating temperature remains within the commercial-grade limits specified in the Intel MAX 10 datasheet. Otherwise, the industrial-grade device must be retained.
What are the operating temperature ranges for these two devices?
The 10M08DCF256I7G (industrial grade) is specified for an ambient temperature range of -40°C to +100°C (TJ = -40°C to +125°C) per Intel MAX 10 industrial-grade specifications. The 10M08DCF256C7G (commercial grade) is specified for 0°C to +85°C ambient (TJ = 0°C to +100°C). Exact limits should be confirmed in the latest Intel MAX 10 FPGA datasheet.
Do both devices have the same logic density and memory resources?
Yes. Both the 10M08DCF256I7G and 10M08DCF256C7G are part of the 10M08 device family, featuring 8,000 logic elements (LEs), 378 Kbits of M9K embedded memory, and 288 Kbits of user flash memory. They also include the same number of 18x18 multipliers and PLLs as defined by the MAX 10 10M08 device specifications.
Are the configuration and power supply requirements identical for both devices?
Yes. Both devices share the same core and I/O voltage requirements as defined for the MAX 10 10M08 family. They support single or dual power supply configurations (e.g., 3.0 V/3.3 V or 1.2 V core) and the same configuration schemes, including internal configuration from on-chip flash. The temperature grade does not alter the electrical supply specifications.
Which device is more suitable for automotive or outdoor applications?
The 10M08DCF256I7G is more suitable for automotive or outdoor applications because its industrial temperature grade supports operation from -40°C to +100°C ambient. The 10M08DCF256C7G commercial grade is limited to 0°C to +85°C and is not recommended for environments outside that range. For automotive qualification, additional AEC-Q100 compliance should be verified separately, as these standard grades may not be automotive-qualified.
Do both devices support the same speed grade and timing performance?
Yes. Both the 10M08DCF256I7G and 10M08DCF256C7G are speed grade 7 (-7) devices. Within the same speed grade, timing parameters such as maximum operating frequency and propagation delays are identical across temperature grades, provided each device is operated within its specified temperature range. The industrial-grade device may exhibit slightly different timing at temperature extremes, so final timing should be validated using the Intel Quartus Prime timing analyzer for the specific operating conditions.
