Key electrical and mechanical differences between the two devices
| Parameter | 10M16DAU324C8G | 10M16DCU324I7G | Why it matters |
|---|---|---|---|
| Family / Series | MAX 10 | MAX 10 | Both belong to the same Intel MAX 10 FPGA family, which is essential for functional substitutability and toolchain compatibility. |
| Logic Elements (LEs) | 16,000 | 16,000 | Identical logic density ensures the same design can fit in either device without resource re-estimation. |
| Package | 324-ball UBGA | 324-ball UBGA | Same package and ball count allow a drop-in replacement on an existing PCB footprint. |
| Operating Temperature Range | 0°C to 85°C (Commercial) | -40°C to 100°C (Industrial) | The industrial-grade version supports harsher environments, so the commercial part cannot substitute in industrial or automotive applications. |
| Speed Grade | 8 (Fastest) | 7 (Slower) | Different speed grades affect maximum operating frequency and timing closure; a slower grade may not meet the same performance targets. |
| Core Supply Voltage (VCCINT) | 1.2 V | 1.2 V | Matching core voltage ensures the same power supply design and decoupling network can be reused. |
| Configuration Flash Memory | Integrated (MAX 10 feature) | Integrated (MAX 10 feature) | Both offer instant-on configuration without external flash, simplifying board design and reducing BOM cost. |
| RoHS Compliance | RoHS Compliant | RoHS Compliant | Both meet environmental regulations, which is required for sale in many regions and for consistency in manufacturing. |

Frequently asked questions
What are the key differences between the 10M16DAU324C8G and the 10M16DCU324I7G?
The primary differences are the operating temperature grade and the speed grade. The 10M16DAU324C8G is specified for commercial temperature range (0°C to 85°C junction) with a speed grade of 8, while the 10M16DCU324I7G is specified for industrial temperature range (-40°C to 100°C junction) with a speed grade of 7. Both devices are Intel (Altera) MAX 10 family FPGAs with 16,000 logic elements in a 324-pin UBGA package.
Are the 10M16DAU324C8G and 10M16DCU324I7G pin-to-pin compatible?
Yes. Both devices share the same 324-pin UBGA (U324) package and the same MAX 10 10M16 device die. The pinout is identical across the commercial and industrial temperature grades and across speed grades 7 and 8 for the same device and package combination, as defined in the Intel MAX 10 device pin-out files.
Can the 10M16DAU324C8G be used as a drop-in replacement for the 10M16DCU324I7G?
Not unconditionally. Although the package and pinout are identical, the 10M16DCU324I7G is rated for the industrial temperature range (-40°C to 100°C junction) and has a faster speed grade (7), while the 10M16DAU324C8G is rated for commercial temperature range (0°C to 85°C junction) and speed grade 8. A drop-in replacement is only valid if the target application operates within the commercial temperature range and the timing closure is re-verified for the slower speed grade.
What is the logic capacity of the 10M16DAU324C8G and 10M16DCU324I7G?
Both devices feature 16,000 logic elements (LEs), 549 Kbits of M9K embedded memory, and 32 embedded 18x18 multipliers. These parameters are identical because both part numbers are based on the same Intel MAX 10 10M16 device core.
Do the 10M16DAU324C8G and 10M16DCU324I7G support the same configuration methods?
Yes. Both devices support the same configuration options available in the Intel MAX 10 family, including internal configuration flash, JTAG configuration, and external configuration via a host or configuration device. The configuration scheme is determined by the device family and package, not by the temperature or speed grade suffix.
What power supply voltages are required for the 10M16DAU324C8G and 10M16DCU324I7G?
Both devices require the standard MAX 10 power rails: VCCINT (1.2 V), VCCA (2.5 V or 3.0 V depending on PLL usage), and VCCIO banks (1.2 V to 3.3 V, depending on I/O standard). These requirements are identical for both part numbers because they share the same device core and package.
Which device is more suitable for industrial applications, the 10M16DAU324C8G or the 10M16DCU324I7G?
The 10M16DCU324I7G is more suitable for industrial applications. Its "I" suffix indicates an industrial temperature grade of -40°C to 100°C junction, whereas the 10M16DAU324C8G has a "C" suffix indicating commercial temperature grade of 0°C to 85°C junction. Industrial applications requiring operation below 0°C or above 85°C should use the 10M16DCU324I7G.
Does the speed grade difference between the 10M16DAU324C8G and 10M16DCU324I7G affect timing performance?
Yes. The 10M16DCU324I7G has speed grade 7, which is faster than speed grade 8 of the 10M16DAU324C8G. This means the industrial-grade device can achieve higher maximum operating frequencies and tighter timing margins. Designers must re-run static timing analysis when migrating between these two speed grades to ensure timing closure.
