Replacement verdict
Compatible functional replacement candidate
The 10M16SCU169C8G and 10M16DCU324I6G are both Intel MAX 10 FPGA devices sharing 16,000 logic elements, but they differ in package, speed grade, and temperature range. The 10M16SCU169C8G offers a faster C8 speed grade in a 169-pin UBGA package with commercial temperature support, while the 10M16DCU324I6G provides an I6 speed grade in a 324-pin UBGA package with industrial temperature support. Functional substitutability is possible only when the target design accommodates the package footprint, timing margin, and thermal environment differences.

Frequently asked questions
What are the key differences between the 10M16SCU169C8G and the 10M16DCU324I6G?
The 10M16SCU169C8G is a MAX 10 FPGA in a 169-pin UBGA package with commercial temperature grade (C8 speed grade), while the 10M16DCU324I6G is a MAX 10 FPGA in a 324-pin UBGA package with industrial temperature grade (I6 speed grade). Both devices feature 16,000 logic elements (LEs), but they differ in package, pin count, speed grade, and operating temperature range.
Are the 10M16SCU169C8G and 10M16DCU324I6G pin-to-pin compatible?
No. The 10M16SCU169C8G uses a 169-pin UBGA package, while the 10M16DCU324I6G uses a 324-pin UBGA package. The different pin counts and package sizes mean they are not pin-to-pin compatible and cannot be used as direct drop-in replacements without PCB redesign.
Do both devices have the same logic density and embedded memory?
Yes. Both the 10M16SCU169C8G and 10M16DCU324I6G are members of the Intel MAX 10 FPGA family with 16,000 logic elements (LEs). They also feature the same embedded memory capacity and number of embedded multipliers, as these resources are determined by the device density (10M16) rather than the package or speed grade.
What is the difference in operating temperature range between the two devices?
The 10M16SCU169C8G has a commercial temperature grade, typically rated for 0°C to 85°C junction temperature. The 10M16DCU324I6G has an industrial temperature grade, typically rated for -40°C to 100°C junction temperature. The industrial-grade device is suitable for harsher environments, while the commercial-grade device is intended for standard office or consumer environments.
What do the speed grades C8 and I6 indicate for these MAX 10 FPGAs?
The C8 suffix on the 10M16SCU169C8G indicates a commercial temperature grade with speed grade 8. The I6 suffix on the 10M16DCU324I6G indicates an industrial temperature grade with speed grade 6. A lower speed grade number generally corresponds to faster performance, so the I6 device offers faster timing characteristics than the C8 device, though the industrial temperature range may affect overall achievable performance.
Can the 10M16DCU324I6G be used as a substitute for the 10M16SCU169C8G in an existing design?
No, not without significant redesign. The 10M16DCU324I6G has a different package (324-pin UBGA vs. 169-pin UBGA), different pinout, and different speed grade. While both have the same 16,000 LE density, the physical and electrical differences prevent direct substitution. A new PCB layout and timing analysis would be required.
Which device is more suitable for industrial applications?
The 10M16DCU324I6G is more suitable for industrial applications due to its industrial temperature grade rating (typically -40°C to 100°C junction temperature). The 10M16SCU169C8G is rated for commercial temperatures (typically 0°C to 85°C junction temperature) and is better suited for consumer or office environments.
Do both devices support the same configuration and IP features of the MAX 10 family?
Yes. Both the 10M16SCU169C8G and 10M16DCU324I6G support the same MAX 10 FPGA family features, including instant-on configuration, integrated analog-to-digital converters (ADCs), and flash memory for single-chip configuration. Feature availability is determined by the device family and density, not by package or temperature grade.
