Replacement verdict
Compatible functional replacement candidate
The 10M40DAF256I7G and 10M40DCF256C7G are functionally compatible as FPGA devices within the same Intel MAX 10 family, sharing identical logic density, package, and I/O configuration. The primary distinction lies in their temperature grade and speed grade, which may affect suitability for specific operating environments. Designers should validate thermal and timing requirements before substituting in applications with strict industrial or commercial temperature constraints.

|---|---|---|---|
| Family / Series | MAX 10 | MAX 10 | Both belong to the same device family, which supports pin-to-pin and functional compatibility at the family level. |
| Logic Elements (LEs) | 40000 | 40000 | Equal logic capacity means both devices can implement the same logic designs without resource constraints. |
| Total RAM Bits | 1269760 | 1269760 | Identical embedded memory allows the same buffering, FIFO, and data storage functions in either device. |
| Number of I/Os | 178 | 178 | Matching I/O counts ensure the same number of external interfaces can be supported on both parts. |
| Package / Case | 256-LBGA | 256-LBGA | Same package and footprint allow direct board-level substitution without layout changes. |
| Operating Temperature Range | -40°C to 100°C (Industrial) | 0°C to 85°C (Commercial) | The industrial-grade part supports harsher environments, while the commercial part is limited to benign conditions; this affects deployment in temperature-sensitive applications. |
| Speed Grade | 7 | 7 | Identical speed grade means both devices meet the same timing performance targets for critical paths. |
| Supply Voltage | 1.2 V core | 1.2 V core | Same core voltage simplifies power supply design and ensures electrical compatibility. |
| Configuration Memory Type | Flash (non-volatile) | Flash (non-volatile) | Both are instant-on, non-volatile devices, eliminating the need for external configuration memory in either case. |

Frequently asked questions
What are the key differences between the 10M40DAF256I7G and the 10M40DCF256C7G?
The primary differences are the operating temperature grade and the speed grade. The 10M40DAF256I7G is specified for industrial temperature range (I7) and uses a faster speed grade (7), while the 10M40DCF256C7G is specified for commercial temperature range (C7) and uses a slower speed grade (7). Both are Intel (Altera) MAX 10 FPGA devices with 40,000 logic elements in a 256-pin FineLine BGA (FBGA) package.
Are the 10M40DAF256I7G and 10M40DCF256C7G pin-to-pin compatible?
Yes. Both devices share the same 256-pin FineLine BGA (FBGA) package and the same MAX 10 10M40 device die. The pinout is identical, so they are pin-to-pin compatible. However, the industrial-temperature version (10M40DAF256I7G) may have different timing characteristics due to the speed grade and temperature range.
Can the 10M40DCF256C7G be used as a direct drop-in replacement for the 10M40DAF256I7G?
Not necessarily. While the package and pinout are identical, the 10M40DAF256I7G is rated for industrial temperature range (-40°C to +100°C junction) and a faster speed grade, whereas the 10M40DCF256C7G is rated for commercial temperature range (0°C to +85°C junction) and a slower speed grade. A drop-in replacement is only valid if the target design operates within the commercial temperature range and the timing closure is re-verified for the slower speed grade.
What is the logic density and package of both devices?
Both the 10M40DAF256I7G and 10M40DCF256C7G are MAX 10 FPGAs with 40,000 logic elements (LEs) and come in a 256-pin FineLine BGA (FBGA) package. They also feature integrated analog-to-digital converters (ADCs), flash memory, and instant-on configuration capabilities typical of the MAX 10 family.
Which device is suitable for industrial applications?
The 10M40DAF256I7G is the industrial-grade option, with a temperature range of -40°C to +100°C junction temperature. The 10M40DCF256C7G is commercial-grade, rated for 0°C to +85°C junction temperature, making it unsuitable for harsh industrial environments unless additional thermal management is provided.
Do both devices support the same configuration methods?
Yes. Both the 10M40DAF256I7G and 10M40DCF256C7G are MAX 10 devices and support the same configuration schemes, including internal configuration from on-chip flash, dual configuration images, and external configuration via JTAG or passive serial. The configuration method is independent of the temperature grade or speed grade.
What speed grade does each device use, and how does it affect performance?
The 10M40DAF256I7G uses speed grade 7 (faster) and the 10M40DCF256C7G uses speed grade 7 (slower). In Intel MAX 10 nomenclature, a lower speed grade number indicates faster performance. Therefore, the 10M40DAF256I7G offers higher maximum operating frequency and tighter timing margins compared to the 10M40DCF256C7G. Designers must re-run static timing analysis if swapping between them.
Are there any differences in power consumption between the two devices?
Power consumption depends on the speed grade, temperature grade, and operating conditions. The 10M40DAF256I7G, being a faster speed grade and industrial-temperature device, may consume slightly more power at the same frequency and voltage compared to the 10M40DCF256C7G. However, exact power figures must be obtained from the Intel MAX 10 power estimator or device datasheet under specific operating conditions.
