Replacement verdict
Compatible functional replacement candidate
The 10M04DCF256A7G is a viable functional replacement candidate for the 10M04DCF256C8G, sharing identical logic density, package, and supply voltage characteristics. The primary distinction lies in speed grade, where the A7G offers a faster maximum operating frequency. Designers should validate timing margins and power dissipation in their specific application before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | 10M04DCF256C8G | 10M04DCF256A7G | Why it matters |
|---|---|---|---|
| Speed Grade | 8 (Commercial) | 7 (Automotive) | Speed grade determines the maximum operating frequency and timing closure margin; grade 7 is faster than grade 8, affecting achievable clock rates and timing performance. |
| Operating Temperature Range | 0°C to +85°C (Commercial) | -40°C to +125°C (Automotive) | The temperature range defines the environments where the device can reliably operate; automotive-grade parts support harsher conditions than commercial-grade parts. |
| Automotive Qualification | No | Yes (AEC-Q100) | AEC-Q100 qualification indicates the device meets automotive reliability and quality standards, which is mandatory for automotive applications. |
| Logic Elements (LEs) | 4,000 | 4,000 | Logic element count determines the amount of programmable logic available for implementing user designs; identical counts mean equivalent logic capacity. |
| Total RAM Bits | 193,536 | 193,536 | Embedded memory capacity affects the ability to store data, buffers, and look-up tables within the FPGA; identical values indicate the same memory resources. |
| Number of I/Os | 178 | 178 | I/O count determines how many external signals the device can interface with; identical counts mean the same interfacing capability. |
| Package / Pin Count | 256-pin FBGA | 256-pin FBGA | Package type and pin count must match for physical board compatibility and footprint interchangeability. |
| Supply Voltage | 1.15 V to 1.25 V (Core) | 1.15 V to 1.25 V (Core) | Core supply voltage must be compatible with the board power design; identical ranges allow the same power delivery network. |
| Configuration Memory Type | SRAM-based (volatile) | SRAM-based (volatile) | Configuration memory type determines whether the device requires external configuration on every power-up; identical types mean the same boot and configuration scheme. |

Frequently asked questions
What are the 10M04DCF256C8G and 10M04DCF256A7G devices?
Both are Intel (formerly Altera) MAX 10 family field-programmable gate arrays (FPGAs) in a 256-ball FineLine BGA (FBGA) package. They share the same 10M04 density grade, which provides 4,000 logic elements (LEs), and both are commercial-grade devices. The suffix differences indicate different speed grades and operating temperature ranges.
What is the difference between the C8 and A7 suffixes on these two part numbers?
The suffix encodes speed grade and temperature grade. In the 10M04DCF256C8G, "C8" denotes commercial temperature range (0°C to 85°C junction) and speed grade 8. In the 10M04DCF256A7G, "A7" denotes automotive temperature range (-40°C to 125°C junction) and speed grade 7. Speed grade 7 is faster than speed grade 8, and the automotive grade supports a wider temperature range.
Are the 10M04DCF256C8G and 10M04DCF256A7G pin-compatible?
Yes. Both devices use the same 256-ball FBGA package with the same pinout, so they are pin-compatible. However, pin compatibility alone does not guarantee direct substitution; speed grade, temperature grade, and timing closure must be validated for the target design.
Can the 10M04DCF256C8G be used as a direct drop-in replacement for the 10M04DCF256A7G?
Not unconditionally. The 10M04DCF256A7G is an automotive-grade device with a faster speed grade (7) and wider temperature range (-40°C to 125°C) than the 10M04DCF256C8G (commercial, 0°C to 85°C, speed grade 8). Replacing an automotive-grade part with a commercial-grade part may violate operating temperature requirements and timing margins. The reverse substitution may also require timing re-validation because speed grade 7 and speed grade 8 have different timing characteristics.
Do both devices support the same configuration and memory features?
Yes. Both are MAX 10 10M04 devices and share the same architecture, including 4,000 LEs, integrated analog-to-digital converter (ADC) blocks, and configuration flash memory. The primary differences are speed grade and temperature grade, not feature set.
Which device is suitable for automotive applications?
The 10M04DCF256A7G is the automotive-grade option, indicated by the "A" in the suffix and its -40°C to 125°C junction temperature range. The 10M04DCF256C8G is a commercial-grade device and is not qualified for automotive temperature ranges.
What is the logic density of both devices?
Both the 10M04DCF256C8G and 10M04DCF256A7G provide 4,000 logic elements (LEs), as indicated by the "10M04" density code in the part number. They also include the same embedded memory and DSP resources typical of the MAX 10 10M04 density grade.
