Replacement verdict
Compatible functional replacement candidate
The 10M16DCU324A7G is a viable functional replacement candidate for the 10M16SCU169C8G in non-timing-critical applications, sharing the same 16,000-logic-element Intel MAX 10 FPGA architecture and core feature set. However, designers must account for the different package footprint, lower speed grade, and narrower commercial temperature range before committing to a drop-in substitution.

Frequently asked questions
What are the key differences between the 10M16SCU169C8G and the 10M16DCU324A7G?
The 10M16SCU169C8G is a MAX 10 FPGA in a 169-pin UBGA package with commercial temperature grade (C8 speed grade), while the 10M16DCU324A7G is a MAX 10 FPGA in a 324-pin UBGA package with automotive temperature grade (A7 speed grade). Both devices feature 16,000 logic elements (LEs), but they differ in package, speed grade, and operating temperature range.
Do the 10M16SCU169C8G and 10M16DCU324A7G have the same logic density?
Yes. Both devices are part of the Intel MAX 10 FPGA family and provide 16,000 logic elements (LEs), along with equivalent embedded memory and DSP resources as defined by the MAX 10 10M16 device specification.
Are the 10M16SCU169C8G and 10M16DCU324A7G pin-to-pin compatible?
No. The 10M16SCU169C8G uses a 169-pin UBGA package, while the 10M16DCU324A7G uses a 324-pin UBGA package. The different pin counts and ball maps mean they are not pin-to-pin compatible and require different PCB footprints.
What temperature grades do the 10M16SCU169C8G and 10M16DCU324A7G support?
The 10M16SCU169C8G is rated for commercial temperature operation (typically 0°C to 85°C junction temperature), while the 10M16DCU324A7G is rated for automotive temperature operation (typically -40°C to 125°C junction temperature), as indicated by the "C" and "A" suffixes in their ordering codes.
What do the speed grade suffixes C8 and A7 indicate for these MAX 10 FPGAs?
The C8 suffix on the 10M16SCU169C8G indicates a commercial-grade speed grade 8, while the A7 suffix on the 10M16DCU324A7G indicates an automotive-grade speed grade 7. Speed grade 7 is faster than speed grade 8, meaning the 10M16DCU324A7G can achieve higher maximum operating frequencies for the same logic design.
Can the 10M16SCU169C8G be used as a direct substitute for the 10M16DCU324A7G in an existing design?
No. Direct substitution is not possible because the two devices differ in package (169-pin UBGA vs 324-pin UBGA), speed grade (8 vs 7), and temperature grade (commercial vs automotive). A redesign of the PCB footprint and revalidation of timing and thermal requirements would be necessary.
Do both the 10M16SCU169C8G and 10M16DCU324A7G support instant-on configuration and integrated flash?
Yes. Both devices belong to the Intel MAX 10 FPGA family, which features integrated flash memory for instant-on configuration, dual configuration images, and analog-to-digital converter (ADC) blocks, as specified in the MAX 10 device family documentation.
Which device is more suitable for automotive applications, the 10M16SCU169C8G or the 10M16DCU324A7G?
The 10M16DCU324A7G is more suitable for automotive applications because its "A" temperature grade and A7 speed grade are specified for automotive operating conditions, whereas the 10M16SCU169C8G is a commercial-grade device intended for standard temperature environments.
