Replacement verdict
Compatible functional replacement candidate
The 10CL040YF484I7G and 10CL040YF484C8G are functionally compatible Cyclone 10 LP FPGA devices sharing identical logic density, package, and pinout, with the primary distinction being the industrial versus commercial temperature grade. The C8G variant offers a faster speed grade, making it suitable for higher-performance commercial applications, while the I7G variant provides extended temperature range support for industrial environments. Both devices are viable substitutes when the target application's thermal and timing requirements are properly matched.

Key electrical and mechanical differences between the two devices
| Parameter | 10CL040YF484I7G | 10CL040YF484C8G | Why it matters |
|---|---|---|---|
| Operating Temperature Range | -40°C to 100°C (Industrial) | 0°C to 85°C (Commercial) | Determines the environmental conditions under which the device can reliably operate; industrial grade supports harsher environments than commercial grade. |
| Speed Grade | 7 (faster) | 8 (slower) | Affects maximum operating frequency and timing closure; a lower number indicates a faster speed grade, which impacts achievable clock rates and performance. |
| Logic Elements (LEs) | 40,000 | 40,000 | Defines the logic capacity available for implementing user designs; identical LE counts mean equivalent logic density. |
| Package / Pin Count | FBGA-484 | FBGA-484 | Determines the physical footprint and PCB layout compatibility; matching packages allow drop-in replacement without board redesign. |
| Supply Voltage (VCCINT) | 1.2 V | 1.2 V | Core voltage must match the board power design; identical values ensure the same power supply can be used. |
| Embedded Memory | 1,161,216 bits | 1,161,216 bits | On-chip memory capacity affects the ability to store data, buffers, and look-up tables within the FPGA; identical capacity means equivalent memory resources. |
| Number of I/O Pins | 325 | 325 | Determines how many external signals the device can interface with; matching I/O counts ensure equivalent connectivity options. |
| Embedded Multipliers (18x18) | 126 | 126 | Hardware multipliers accelerate DSP operations; identical counts mean the same digital signal processing capability. |
| Manufacturer Part Status / Grade | Industrial grade | Commercial grade | Indicates the intended application environment and qualification level; industrial parts are tested for wider temperature ranges and harsher conditions. |

Frequently asked questions
What are the 10CL040YF484I7G and 10CL040YF484C8G devices?
Both are Intel (formerly Altera) Cyclone 10 LP field-programmable gate arrays (FPGAs) in the same 484-pin FineLine BGA (FBGA) package. They share the same logic density of 40,000 logic elements (LEs), the same package and pinout, and the same core architecture. The difference between the two part numbers is the speed grade and the operating temperature range, indicated by the suffix codes.
What do the speed grade and temperature suffixes I7G and C8G indicate?
In Intel FPGA ordering codes, the letter and digit before the final G denote speed grade and temperature range. The "I7" suffix indicates an industrial temperature grade device with speed grade 7. The "C8" suffix indicates a commercial temperature grade device with speed grade 8. The trailing "G" indicates RoHS-compliant lead-free packaging. Industrial-grade devices are specified over a wider ambient temperature range than commercial-grade devices.
Are the 10CL040YF484I7G and 10CL040YF484C8G pin-compatible?
Yes. Both devices use the same 484-pin FineLine BGA package with the same pinout, because they are the same Cyclone 10 LP 40K LE die in the same package. This means the PCB footprint and pin assignments are identical, allowing either device to be placed on the same board design provided the speed grade and temperature requirements are met.
Can the 10CL040YF484C8G be used as a drop-in replacement for the 10CL040YF484I7G?
Not unconditionally. Although the package and pinout are identical, the two devices differ in speed grade and temperature grade. The I7G is an industrial-temperature, speed grade 7 device, while the C8G is a commercial-temperature, speed grade 8 device. A drop-in replacement is only valid if the target design's timing closure, operating temperature range, and reliability requirements are satisfied by the commercial-grade, speed grade 8 part. Timing and thermal margins must be re-validated against the manufacturer datasheet before substitution.
Which device supports a wider operating temperature range?
The 10CL040YF484I7G, with the "I" industrial temperature grade suffix, supports a wider ambient operating temperature range than the 10CL040YF484C8G, which carries the "C" commercial temperature grade suffix. The exact temperature limits should be confirmed from the Intel Cyclone 10 LP device datasheet, as they are defined by the manufacturer's specifications.
Does the speed grade difference affect maximum operating frequency?
Yes. Speed grade directly affects the achievable maximum frequency (Fmax) and timing performance of the FPGA fabric and I/O. A lower speed grade number generally corresponds to faster performance. Because the 10CL040YF484I7G is speed grade 7 and the 10CL040YF484C8G is speed grade 8, their timing characteristics differ. Designers must consult the Intel Cyclone 10 LP datasheet timing models to confirm whether a given design meets its timing requirements on each specific speed grade.
Are both devices RoHS compliant and lead-free?
Yes. Both the 10CL040YF484I7G and 10CL040YF484C8G carry the trailing "G" in their ordering code, which indicates RoHS-compliant, lead-free packaging as defined by Intel's ordering information. Designers should still verify the current compliance status against the manufacturer's latest product documentation and environmental declarations.
What factors should be evaluated before choosing between these two parts?
The primary selection factors are the required operating temperature range and the required timing performance. Choose the 10CL040YF484I7G when the application demands industrial temperature operation and/or the faster speed grade 7 timing. Choose the 10CL040YF484C8G when commercial temperature operation is acceptable and speed grade 8 timing meets the design's Fmax requirements. In both cases, verify logic utilization, I/O count, power budget, and configuration requirements against the Intel Cyclone 10 LP datasheet.
