Replacement verdict
Compatible functional replacement candidate
The 10M40DAF256C8G and 10M40DCF256C7G are both Intel MAX 10 FPGA devices in the same 256-ball FBGA package with identical logic density and feature set, making them strong functional replacement candidates. The primary distinction is speed grade and temperature range, so the 10M40DCF256C7G can substitute for the 10M40DAF256C8G in most designs provided the faster speed grade and commercial temperature rating are acceptable for the target application.

Frequently asked questions
What are the key differences between the 10M40DAF256C8G and the 10M40DCF256C7G?
The primary differences are the speed grade and the operating temperature range. The 10M40DAF256C8G is specified with a speed grade of 8 and an extended commercial temperature range of 0°C to 85°C (junction). The 10M40DCF256C7G is specified with a faster speed grade of 7 and an industrial temperature range of -40°C to 100°C (junction). Both devices are members of the Intel (formerly Altera) MAX 10 family, feature 40,000 logic elements, and are housed in a 256-pin FineLine BGA (FBGA) package.
Are the 10M40DAF256C8G and 10M40DCF256C7G pin-to-pin compatible?
Yes. Both devices share the same 256-pin FineLine BGA (FBGA) package with identical pinouts as defined by the MAX 10 device family. This allows for a common PCB footprint. However, designers must verify that the different speed grades and temperature ranges meet the timing and environmental requirements of the target application before substituting one for the other.
Can the 10M40DAF256C8G be used as a direct drop-in replacement for the 10M40DCF256C7G?
Not necessarily. While the package and pinout are identical, the 10M40DCF256C7G has a faster speed grade (7 vs. 8) and a wider industrial temperature range (-40°C to 100°C vs. 0°C to 85°C). A direct replacement would require re-validating the design's timing closure at the slower speed grade and confirming that the commercial temperature range is sufficient for the application. Conversely, replacing the C8G with the C7G may require checking for timing violations due to the faster speed grade.
What is the logic density and memory capacity of these devices?
Both the 10M40DAF256C8G and 10M40DCF256C7G feature 40,000 logic elements (LEs). They also include 1,260 Kbits of M9K embedded memory blocks and 288 Kbits of user flash memory (UFM). These parameters are consistent across the MAX 10 10M40 device density.
Do these devices support instant-on configuration and integrated analog-to-digital conversion?
Yes. Both devices are part of the MAX 10 family, which features instant-on configuration from on-chip flash memory. They also integrate analog-to-digital converter (ADC) blocks. The 10M40 devices include two ADC blocks with a 12-bit resolution and up to 1 MSPS sampling rate, subject to the specific speed grade and temperature range.
What are the operating temperature ranges for the 10M40DAF256C8G and 10M40DCF256C7G?
The 10M40DAF256C8G is rated for commercial operation with a junction temperature (Tj) range of 0°C to 85°C. The 10M40DCF256C7G is rated for industrial operation with a junction temperature (Tj) range of -40°C to 100°C. The industrial version is suitable for harsher environments, while the commercial version is intended for controlled environments.
What are the speed grade implications for timing closure when comparing these two parts?
The 10M40DCF256C7G has a faster speed grade (7) compared to the 10M40DAF256C8G (8). A lower speed grade number indicates faster performance. When migrating a design from the C7G to the C8G, the slower speed grade may reduce the maximum operating frequency (Fmax) and could cause timing violations. Conversely, migrating from the C8G to the C7G generally provides additional timing margin. In both cases, a full timing analysis must be performed using the respective device timing models.
Are these devices RoHS compliant and lead-free?
Yes. Both the 10M40DAF256C8G and 10M40DCF256C7G are offered in RoHS-compliant, lead-free packages. The 256-pin FineLine BGA (FBGA) package is compatible with lead-free soldering processes. Designers should refer to the manufacturer's packaging and ordering information for specific compliance documentation.
