5CSEBA2U19I7N vs 5CSEBA2U19C8N

Both are Intel (formerly Altera) Cyclone V SE SoC FPGA devices in the same 484-pin UBGA package (19 mm x 19 mm). They integrate a dual-core ARM Cortex-A9 hard processor system (HPS) with FPGA fabric, and both carry the 5CSEBA2 device density and U19 package identifier. The suffixes C8N and I7N denote different speed grades and temperature grades.

The suffix encodes speed grade and temperature grade. In the 5CSEBA2U19C8N, "C8" indicates a commercial temperature grade with speed grade 8. In the 5CSEBA2U19I7N, "I7" indicates an industrial temperature grade with speed grade 7. Speed grade 7 is faster than speed grade 8, and the industrial grade supports a wider operating temperature range than the commercial grade.

Yes. Both devices use the same U19 package, which is a 484-pin UBGA with identical pinout for the Cyclone V SE 5CSEBA2 device. Because the package and device density are the same, the pin assignments and PCB land pattern are identical, allowing either device to be placed on the same footprint.

They are not directly interchangeable without design validation. The 5CSEBA2U19I7N has a faster speed grade (7 vs 8) and a wider industrial temperature range, while the 5CSEBA2U19C8N is commercial grade with a slower speed grade. Timing closure, power consumption, and thermal performance must be re-verified against the specific speed grade and temperature grade used in the target design.

The 5CSEBA2U19C8N is a commercial-grade device, and the 5CSEBA2U19I7N is an industrial-grade device. Industrial-grade Cyclone V devices are specified for a wider ambient temperature range than commercial-grade devices. Exact temperature limits should be confirmed from the Intel Cyclone V device datasheet, as they depend on the specific device and package.

Yes. Speed grade 7 (5CSEBA2U19I7N) provides faster FPGA fabric timing performance than speed grade 8 (5CSEBA2U19C8N). This affects maximum operating frequency, timing closure margins, and achievable performance in the FPGA portion of the device. The HPS performance may also be affected depending on the configured clock frequencies.

Yes. Both the 5CSEBA2U19C8N and 5CSEBA2U19I7N are Cyclone V SE SoC FPGA devices supported by Intel Quartus Prime software and the SoC FPGA Embedded Design Suite. Device selection in the tools includes the specific speed grade and temperature grade, so the correct ordering code must be selected during project configuration.

For industrial applications requiring a wider temperature range, the 5CSEBA2U19I7N is the appropriate choice because it is industrial-grade. The 5CSEBA2U19C8N is commercial-grade and is intended for applications within the commercial temperature range. Final selection should be based on the actual operating environment and verified against the Intel Cyclone V datasheet.
