Replacement verdict
Compatible functional replacement candidate
The 10M40DCF256A7G and 10M40DAF256C7G are both Intel MAX 10 field-programmable gate arrays sharing the same 40,000-logic-element density, 256-ball FineLine BGA package, and dual-configuration flash architecture, making them functionally interchangeable in most designs. The primary distinction lies in their speed grade and operating temperature range, which must be validated against the target application's timing and environmental requirements before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | 10M40DCF256A7G | 10M40DAF256C7G | Why it matters |
|---|---|---|---|
| Family / Series | MAX 10 | MAX 10 | Both parts belong to the same Intel MAX 10 FPGA family, which is the baseline requirement for functional substitutability. |
| Logic Elements (LEs) | 40,000 | 40,000 | Matching logic density ensures equivalent programmable logic capacity for the target design. |
| Package | 256-FBGA (17x17) | 256-FBGA (17x17) | Identical package and footprint allow drop-in board-level replacement without PCB redesign. |
| Operating Temperature Range | 0°C to +85°C (Commercial) | 0°C to +85°C (Commercial) | Same temperature grade means both parts suit the same thermal environment and application conditions. |
| Speed Grade | 7 (Fastest) | 7 (Fastest) | Identical speed grade ensures the same timing performance and maximum operating frequency. |
| Embedded Memory | 1,260 Kbit | 1,260 Kbit | Equal on-chip memory capacity supports the same buffering, FIFO, and data storage requirements. |
| 18x18 Multipliers | 126 | 126 | Same number of hardware multipliers ensures equivalent DSP throughput for arithmetic-intensive functions. |
| Configuration Method | Dual Configuration (CF) | Single Configuration (AF) | Dual-configuration devices support two independent images with fail-safe fallback, while single-configuration devices store only one image; this affects boot reliability and field-update strategy. |
| User I/O Count | 178 | 178 | Matching I/O count preserves the same interface capability and pinout flexibility for peripheral connections. |
| Supply Voltage (Core) | 1.2 V | 1.2 V | Same core voltage means identical power supply design and no change to the power delivery network. |

Frequently asked questions
What are the 10M40DCF256A7G and 10M40DAF256C7G devices?
Both are Intel (formerly Altera) MAX 10 field-programmable gate arrays (FPGAs) in the 10M40 density class, featuring 40,000 logic elements (LEs), non-volatile integrated flash configuration, and a 256-ball FineLine BGA (FBGA) package. The 10M40DCF256A7G is specified with a commercial temperature grade and speed grade 7, while the 10M40DAF256C7G is specified with an automotive temperature grade and speed grade 7.
What is the difference between the 10M40DCF256A7G and 10M40DAF256C7G?
The primary differences are the temperature grade and the corresponding ordering-code designator. The 10M40DCF256A7G uses the "C" designator for commercial temperature range (typically 0°C to 85°C junction). The 10M40DAF256C7G uses the "A" designator for automotive temperature range (typically -40°C to 125°C junction, per Intel MAX 10 ordering information). Both share the same 10M40 density, 256-ball FBGA package, and speed grade 7.
Are the 10M40DCF256A7G and 10M40DAF256C7G pin-compatible?
Yes. Both devices are offered in the same 256-ball FineLine BGA (FBGA) package with the same ballout for the 10M40 density. Package compatibility alone does not guarantee interchangeability in a design; the temperature grade difference must be validated against the target application's operating conditions.
Can the 10M40DCF256A7G be used as a drop-in replacement for the 10M40DAF256C7G?
Not unconditionally. Although both are 10M40 devices in the same 256-ball FBGA package with speed grade 7, the 10M40DAF256C7G is rated for the automotive temperature range while the 10M40DCF256A7G is rated for the commercial temperature range. A drop-in replacement is only valid if the target design's operating temperature remains within the commercial range and all other specifications are verified against Intel MAX 10 documentation.
What is the logic density of the 10M40DCF256A7G and 10M40DAF256C7G?
Both devices provide 40,000 logic elements (LEs), which is the defining characteristic of the 10M40 density class in the Intel MAX 10 FPGA family. They also include integrated analog-to-digital converter (ADC) blocks and flash memory for configuration, as documented in Intel MAX 10 device datasheets.
Do both devices support instant-on configuration?
Yes. As MAX 10 FPGAs, both the 10M40DCF256A7G and 10M40DAF256C7G feature integrated non-volatile flash configuration memory, enabling instant-on operation without the need for an external configuration device. This is a family-level feature of Intel MAX 10 devices.
Which temperature grade should be selected for automotive applications?
The 10M40DAF256C7G, identified by the "A" designator in its ordering code, is the automotive temperature grade variant. The 10M40DCF256A7G, with the "C" designator, is the commercial temperature grade variant. Selection should be based on the actual operating temperature requirements of the target system and verified against Intel MAX 10 ordering information.
Are the speed grades of the 10M40DCF256A7G and 10M40DAF256C7G the same?
Yes. Both devices are specified with speed grade 7, as indicated by the "7" in their ordering codes. Speed grade affects timing characteristics such as maximum operating frequency and propagation delays, and both parts share the same speed grade designation within the Intel MAX 10 family.
