Replacement verdict
Compatible functional replacement candidate
The 10M50DAF256I6G and 10M50DCF256A7G are both Intel MAX 10 FPGA devices sharing the same 50,000 logic element density and 256-ball FineLine BGA footprint, making them functionally interchangeable at the board level. However, they differ in speed grade and operating temperature range, so the 10M50DCF256A7G should only be considered a direct substitute for the 10M50DAF256I6G in applications where the relaxed speed and commercial temperature ratings are acceptable. Designers must validate timing closure and thermal margins before committing to this replacement.

Frequently asked questions
What are the key differences between the 10M50DAF256I6G and the 10M50DCF256A7G?
The 10M50DAF256I6G is a MAX 10 FPGA with 50,000 logic elements in a 256-pin FineLine BGA package, rated for industrial temperature grade (I6) with a speed grade of 6. The 10M50DCF256A7G is also a MAX 10 FPGA with 50,000 logic elements in a 256-pin FineLine BGA package, but it is rated for automotive temperature grade (A7) with a speed grade of 7. The primary differences are the temperature grade, speed grade, and the associated operating conditions and performance characteristics.
Are the 10M50DAF256I6G and 10M50DCF256A7G pin-to-pin compatible?
Both devices are offered in the same 256-pin FineLine BGA (FBGA) package, which typically provides the same physical footprint and ball map for the MAX 10 family. However, designers must verify the pinout and any device-specific configuration pins against the respective datasheets before considering them drop-in replacements, as I/O standards and dedicated pin functions may differ by speed grade or temperature grade options.
What is the difference in operating temperature range between the 10M50DAF256I6G and the 10M50DCF256A7G?
The 10M50DAF256I6G is specified for industrial temperature range, typically -40°C to +100°C junction temperature (TJ). The 10M50DCF256A7G is specified for automotive temperature range, typically -40°C to +125°C junction temperature (TJ). The exact limits should be confirmed in the respective device datasheets, as the automotive grade supports a wider high-temperature range.
Can the 10M50DAF256I6G be used as a substitute for the 10M50DCF256A7G in an automotive application?
No, the 10M50DAF256I6G is rated for industrial temperature range and is not qualified to automotive standards. The 10M50DCF256A7G is the automotive-grade variant and should be used for automotive applications requiring AEC-Q100 qualification and the extended temperature range. Substitution would require validation against the target application's environmental and reliability requirements.
What are the speed grade implications of the 10M50DAF256I6G versus the 10M50DCF256A7G?
The 10M50DAF256I6G has a speed grade of 6, while the 10M50DCF256A7G has a speed grade of 7. In Intel MAX 10 FPGA nomenclature, a lower speed grade number generally indicates faster performance. Therefore, the 10M50DAF256I6G (speed grade 6) typically offers higher maximum operating frequencies and lower propagation delays compared to the 10M50DCF256A7G (speed grade 7). Designers must re-timing-analyze if swapping between these speed grades.
Do both the 10M50DAF256I6G and 10M50DCF256A7G support the same configuration options?
Both devices are members of the Intel MAX 10 FPGA family and support similar configuration features, including internal configuration flash, dual configuration images, and instant-on capability. However, the exact configuration options, including supported configuration schemes and any device-specific settings, should be verified in the respective datasheets, as temperature grade and speed grade may affect certain configuration timing parameters.
What are the typical applications for the 10M50DAF256I6G and the 10M50DCF256A7G?
The 10M50DAF256I6G is typically used in industrial applications such as motor control, industrial networking, and embedded systems requiring a balance of performance and industrial temperature support. The 10M50DCF256A7G is designed for automotive applications such as advanced driver assistance systems (ADAS), infotainment, and vehicle networking, where automotive qualification and extended temperature range are required.
Are the 10M50DAF256I6G and 10M50DCF256A7G RoHS compliant?
Intel MAX 10 FPGA devices, including the 10M50DAF256I6G and 10M50DCF256A7G, are generally available in RoHS-compliant packages. However, compliance status can vary by ordering code and packaging option. Designers should confirm RoHS and lead-free status through the manufacturer's product material declaration or distributor documentation for the specific ordering part number.
