10M16DCF484C8G vs 10M16DCF484A7G

Both are Intel (formerly Altera) MAX 10 field-programmable gate array (FPGA) devices in the 10M16 density family, supplied in a 484-pin FineLine BGA (FBGA) package. The 10M16DCF484C8G and 10M16DCF484A7G share the same 16,000 logic element (LE) density, package, and pin count, but differ in their speed grade and specified operating temperature range as indicated by the ordering code suffixes.

In Intel MAX 10 ordering codes, the suffix encodes speed grade and temperature grade. The "C8" designation indicates a commercial temperature grade with speed grade 8, while "A7" indicates an automotive temperature grade with speed grade 7. Speed grade 7 is a faster speed grade than speed grade 8, and the automotive grade supports a wider temperature range than the commercial grade. Designers must confirm exact temperature ranges and timing specifications in the official Intel MAX 10 datasheet before substitution.

Yes. Both devices use the same 484-pin FineLine BGA package with the same pinout for the 10M16 density in that package option. Because the package and pin assignments are identical, they are physically and pin-compatible, allowing the same PCB footprint to accept either device. Electrical and timing differences related to speed grade and temperature grade must still be evaluated.

Not unconditionally. Although both are 10M16 devices in the same 484-pin FBGA package, the A7 variant is an automotive temperature grade part with a faster speed grade (7) than the C8 commercial variant (8). A drop-in replacement requires verifying that the target design's timing closure, operating temperature range, and any automotive qualification requirements are satisfied by the replacement device. Intel documentation should be consulted for exact specifications.

Both are MAX 10 10M16 devices and therefore belong to the same product family, which includes features such as integrated analog-to-digital converters, flash memory for dual configuration, and instant-on capability. However, exact feature availability and performance limits can depend on speed grade and temperature grade. The specific datasheet sections for each ordering code should be reviewed to confirm identical feature support.

The 10M16DCF484A7G, indicated by the "A" in the ordering code, is the automotive temperature grade variant and is the appropriate choice for automotive applications that require extended temperature operation and automotive-grade qualification. The 10M16DCF484C8G is a commercial temperature grade device and is not intended for automotive temperature environments. Final selection must be based on the requirements defined in the applicable Intel MAX 10 ordering information and datasheet.

Before substituting, verify the operating temperature range, speed grade timing performance, power consumption, configuration requirements, and any qualification or certification requirements applicable to the end application. Because the two devices differ in speed grade and temperature grade, timing analysis and thermal analysis should be re-run. All parameters should be confirmed against the official Intel MAX 10 device datasheet and ordering information.
