Replacement verdict
Compatible functional replacement candidate
The 10M16DCU324I7G is a functionally compatible replacement candidate for the 10M16DCU324C8G, as both devices share the same Intel MAX 10 FPGA family, 16,000 logic elements, 324-pin UBGA package, and identical I/O and transceiver resources. The primary distinction is the temperature grade and speed grade, with the industrial-grade I7G offering a wider operating temperature range and faster timing closure than the commercial-grade C8G. Designers should validate timing margins and thermal requirements before substituting in applications that are temperature-sensitive or timing-critical.

Frequently asked questions
What are the key differences between the 10M16DCU324C8G and the 10M16DCU324I7G?
The primary differences are the operating temperature grade and the speed grade. The 10M16DCU324C8G 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 field-programmable gate arrays (FPGAs) with 16,000 logic elements in a 324-pin UBGA package.
Are the 10M16DCU324C8G and 10M16DCU324I7G pin-to-pin compatible?
Yes. Both devices share the same 324-pin UBGA package (package code U324) and the same device family (MAX 10 10M16). The pinout and package dimensions are identical, so they are pin-to-pin compatible. However, the industrial-grade 10M16DCU324I7G may have different timing characteristics due to its faster speed grade (7 vs. 8).
Can the 10M16DCU324C8G be used as a direct drop-in replacement for the 10M16DCU324I7G?
Not unconditionally. While the package and pinout are identical, the 10M16DCU324I7G is rated for a wider industrial temperature range (-40°C to 100°C junction) and has a faster speed grade (7). Replacing an industrial-grade device with a commercial-grade device may violate the target system's thermal requirements. Additionally, timing closure must be re-verified because the speed grade difference affects propagation delays and maximum operating frequency.
What is the logic capacity of the 10M16DCU324C8G and 10M16DCU324I7G?
Both devices feature 16,000 logic elements (LEs), which is the defining characteristic of the 10M16 device density within the Intel MAX 10 FPGA family. They also include embedded memory blocks, analog-to-digital converter (ADC) blocks, and internal configuration flash memory, as documented in the Intel MAX 10 FPGA device overview.
What temperature grades apply to the 10M16DCU324C8G and 10M16DCU324I7G?
The 10M16DCU324C8G is a commercial-grade device, typically specified for a junction temperature range of 0°C to 85°C. The 10M16DCU324I7G is an industrial-grade device, typically specified for a junction temperature range of -40°C to 100°C. These temperature ranges are defined in the Intel MAX 10 FPGA datasheet and must be respected for reliable operation.
Do the 10M16DCU324C8G and 10M16DCU324I7G support the same configuration methods?
Yes. Both devices are part of the Intel MAX 10 family, which features internal configuration flash memory. They support the same configuration schemes, including active serial (AS), passive serial (PS), and JTAG configuration, as well as internal configuration from the on-chip flash. The configuration methodology is identical across both speed and temperature grades.
Which device is more suitable for automotive or industrial applications?
The 10M16DCU324I7G is more suitable for industrial and automotive applications that require operation below 0°C or above 85°C junction temperature. Its industrial temperature rating (-40°C to 100°C junction) and faster speed grade (7) make it preferable for harsh environments and timing-critical designs. The 10M16DCU324C8G is intended for commercial applications with controlled temperature environments.
Are the 10M16DCU324C8G and 10M16DCU324I7G RoHS compliant?
Yes. Both devices are offered in RoHS-compliant packages as part of Intel's MAX 10 FPGA product line. The "G" suffix in the ordering code indicates RoHS compliance and lead-free packaging. Specific compliance documentation should be verified through Intel's product material declarations or authorized distributors such as DigiKey or Mouser.
