Replacement verdict
Compatible functional replacement candidate
The 10CL080YF484I7G and 10CL040YF484C8G share the same 484-pin FBGA package, Cyclone 10 LP device family, and 1.0 V core architecture, making them pin-compatible candidates. However, the 10CL080YF484I7G offers approximately twice the logic density and operates over the industrial temperature range, while the 10CL040YF484C8G is a commercial-grade device with lower logic capacity. Designers must verify logic utilization, timing closure, and thermal requirements before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | 10CL080YF484I7G | 10CL040YF484C8G | Why it matters |
|---|---|---|---|
| Logic Elements (LEs) | 8,000 | 4,000 | Logic capacity determines how much custom digital logic can be implemented; a device with half the LEs cannot host a design that requires the larger capacity. |
| Total RAM Bits | 294,912 | 126,976 | Embedded memory limits buffering, FIFOs, and data storage inside the FPGA; insufficient RAM blocks prevent a design from fitting. |
| Maximum User I/O Pins | 278 | 278 | I/O count determines how many external signals the device can interface with; matching counts supports similar board-level connectivity. |
| Speed Grade | 7 (fastest) | 8 (slower) | Speed grade affects maximum operating frequency and timing closure; a slower grade may not meet the same clock requirements. |
| Operating Temperature Range | -40°C to +100°C (Industrial) | 0°C to +85°C (Commercial) | Temperature grade determines suitability for harsh or industrial environments; commercial parts may not be reliable over extended temperature ranges. |
| Package | 484-pin FBGA | 484-pin FBGA | Package and pinout must match for a drop-in replacement on an existing PCB footprint. |
| Supply Voltage (Core) | 1.2 V | 1.2 V | Core voltage must match the board power design; a mismatch would require additional regulation or cause damage. |
| Number of PLLs | 2 | 2 | PLLs provide clock synthesis and management; matching counts supports similar clocking architectures. |
| Embedded Multipliers (18x18) | 48 | 46 | DSP blocks determine arithmetic throughput for signal processing; fewer multipliers can bottleneck compute-intensive designs. |

Frequently asked questions
What are the key differences between the 10CL080YF484I7G and the 10CL040YF484C8G?
The 10CL080YF484I7G is a Cyclone 10 LP FPGA with 80,000 logic elements and an industrial temperature grade of -40°C to 100°C (I7). The 10CL040YF484C8G has 40,000 logic elements and a commercial temperature grade of 0°C to 85°C (C8). Both devices are offered in the same 484-pin FBGA package (YF484).
Are the 10CL080YF484I7G and 10CL040YF484C8G pin-compatible?
Both devices use the same 484-pin FineLine BGA (FBGA) package with the YF484 suffix, which defines a common pinout and PCB footprint. However, because the logic density and temperature grade differ, designers must verify I/O bank assignments, power sequencing, and configuration pin behavior against the respective datasheets before treating them as drop-in replacements.
Can the 10CL040YF484C8G be used as a substitute for the 10CL080YF484I7G in an existing design?
Substitution is not guaranteed. The 10CL040YF484C8G provides only half the logic elements (40,000 vs 80,000) and a narrower commercial temperature range (0°C to 85°C vs -40°C to 100°C). A design that requires the higher logic capacity or industrial temperature range of the 10CL080YF484I7G cannot be reliably downgraded without a full resource, timing, and thermal re-evaluation.
What temperature grades do the 10CL080YF484I7G and 10CL040YF484C8G support?
The 10CL080YF484I7G is rated for the industrial temperature range of -40°C to 100°C junction temperature, indicated by the "I7" speed/temperature suffix. The 10CL040YF484C8G is rated for the commercial temperature range of 0°C to 85°C junction temperature, indicated by the "C8" suffix. These grades are defined in the Intel Cyclone 10 LP device datasheet.
Do both devices belong to the same FPGA family and use the same configuration scheme?
Yes. Both the 10CL080YF484I7G and 10CL040YF484C8G are members of the Intel Cyclone 10 LP family. They support the same configuration schemes, including active serial (AS), passive serial (PS), and JTAG, and use the same configuration voltage levels as specified in the Cyclone 10 LP documentation.
What logic element counts and embedded memory resources distinguish these two devices?
The 10CL080YF484I7G contains 80,000 logic elements, while the 10CL040YF484C8G contains 40,000 logic elements. Embedded memory blocks and multiplier resources scale with density in the Cyclone 10 LP family, so the 10CL080YF484I7G offers proportionally more M9K memory blocks and embedded multipliers than the 10CL040YF484C8G. Exact counts should be confirmed in the Intel Cyclone 10 LP device overview.
Which device is better suited for industrial versus commercial applications?
The 10CL080YF484I7G, with its industrial temperature rating of -40°C to 100°C, is intended for industrial, automotive-adjacent, and harsh-environment applications. The 10CL040YF484C8G, rated for 0°C to 85°C, is intended for commercial and consumer applications where the narrower temperature range and lower logic density are sufficient.
Are the speed grades of the 10CL080YF484I7G and 10CL040YF484C8G the same?
No. The 10CL080YF484I7G uses speed grade 7, while the 10CL040YF484C8G uses speed grade 8. In the Cyclone 10 LP family, a lower speed grade number indicates faster performance, so the 10CL080YF484I7G offers higher maximum operating frequency and tighter timing than the 10CL040YF484C8G. Designers must re-run static timing analysis if migrating between these speed grades.
