Replacement verdict
Compatible functional replacement candidate
The 10M16DCU324C8G and 10M16SCU324C8G are functionally compatible FPGA candidates sharing the same Intel MAX 10 device family, 16,000 logic elements, 324-ball UBGA package, and commercial temperature grade. The primary distinction is the integrated high-speed transceiver capability: the 10M16DCU324C8G includes transceiver blocks while the 10M16SCU324C8G does not. Designers must validate transceiver-dependent interfaces before substituting, but core logic, I/O, and package footprint remain interchangeable.

Frequently asked questions
What are the 10M16DCU324C8G and 10M16SCU324C8G devices?
Both are Intel (formerly Altera) MAX 10 family field-programmable gate arrays (FPGAs) in a 324-pin UBGA package with a speed grade of 8. The 10M16DCU324C8G is a dual-supply device, while the 10M16SCU324C8G is a single-supply device, as indicated by the "D" and "S" in their respective part numbers.
What is the difference between the "D" and "S" in the part numbers 10M16DCU324C8G and 10M16SCU324C8G?
The "D" denotes a dual-supply MAX 10 FPGA, which requires both 1.2 V and 2.5 V (or 3.3 V) power rails for core and I/O operation. The "S" denotes a single-supply MAX 10 FPGA, which operates from a single 3.3 V supply for both core and I/O, simplifying power design.
Are the 10M16DCU324C8G and 10M16SCU324C8G pin-compatible?
Yes, both devices share the same 324-pin UBGA package footprint and pinout, allowing them to be used interchangeably on the same PCB layout. However, power supply connections differ due to the dual-supply versus single-supply architecture, so the power delivery network must be designed accordingly.
Do the 10M16DCU324C8G and 10M16SCU324C8G have the same logic density and resources?
Yes, both are 10M16 devices with 16,000 logic elements (LEs), 549 Kbits of M9K embedded memory, and 288 embedded 18x18 multipliers. They also include the same number of user I/O pins and analog-to-digital converter (ADC) blocks, as they belong to the same MAX 10 10M16 density tier.
Can the 10M16DCU324C8G and 10M16SCU324C8G be used in the same design interchangeably?
They can be used interchangeably only if the power supply architecture is compatible. The dual-supply 10M16DCU324C8G requires a 1.2 V core supply and a separate I/O supply, while the single-supply 10M16SCU324C8G requires only a 3.3 V supply. The PCB power plane and regulator design must match the selected device.
What are the operating voltage requirements for the 10M16DCU324C8G and 10M16SCU324C8G?
The 10M16DCU324C8G (dual-supply) requires a 1.2 V core voltage (VCCINT) and a 2.5 V or 3.3 V I/O voltage (VCCIO). The 10M16SCU324C8G (single-supply) requires a single 3.3 V supply (VCC) for both core and I/O. Both devices also require a 1.5 V or 1.8 V supply for the ADC block, if used.
Are the 10M16DCU324C8G and 10M16SCU324C8G supported by the same development tools?
Yes, both devices are supported by Intel Quartus Prime software, including the Standard Edition and Lite Edition, with the MAX 10 device support package installed. The same design files, pin assignments, and IP cores can be used for either device, provided the power supply constraints are respected.
What are the typical applications for the 10M16DCU324C8G and 10M16SCU324C8G?
Both devices are used in applications requiring moderate logic density, such as industrial control, motor control, sensor fusion, communication interfaces, and embedded system glue logic. The single-supply 10M16SCU324C8G is often preferred in cost-sensitive or space-constrained designs where a single 3.3 V rail is available, while the dual-supply 10M16DCU324C8G offers lower core power consumption for higher-performance logic.
Do the 10M16DCU324C8G and 10M16SCU324C8G have the same configuration flash memory?
Yes, both devices include on-chip configuration flash memory (CFM) that allows them to be used in instant-on applications. They support the same configuration schemes, including active serial (AS), passive serial (PS), and JTAG, and both can be programmed via the Intel Quartus Prime Programmer.
