Replacement verdict
Compatible functional replacement candidate
The 10CL040YF484I7G and 10CL080YF484C8G share the same 484-pin FineLine BGA package, Cyclone 10 LP device family, and 1.2 V core architecture, making them functionally interchangeable at the board level. However, the 10CL080YF484C8G offers double the logic density and a faster speed grade, while the 10CL040YF484I7G provides a wider industrial temperature range. Designers should validate timing closure, power budget, and thermal margins before substituting one for the other in production.

Key electrical and mechanical differences between the two devices
| Parameter | 10CL040YF484I7G | 10CL080YF484C8G | Why it matters |
|---|---|---|---|
| Logic Elements (LEs) | 40,000 | 80,000 | LE count determines the amount of programmable logic available; a design that fits in 40K LEs may not fit in 80K and vice versa, directly affecting functional substitutability. |
| Total RAM Bits | 1,161,216 | 2,810,880 | Embedded memory capacity limits the size of buffers, FIFOs, and data storage a design can implement; insufficient RAM prevents a drop-in replacement. |
| Number of I/Os | 277 | 277 | I/O count must match the board's pin requirements; identical I/O counts support pin-compatible substitution. |
| Package / Case | 484-FBGA (23x23) | 484-FBGA (23x23) | Physical package and footprint must match for the part to be soldered onto the same PCB land pattern. |
| Supply Voltage | 1.2 V | 1.2 V | Core supply voltage must be compatible with the board's power delivery; a mismatch can damage the device or prevent operation. |
| Operating Temperature Range | -40°C to 100°C (TJ) | 0°C to 85°C (TJ) | Industrial-grade temperature range is required for harsh environments; a commercial-grade part may not meet the application's thermal requirements. |
| Speed Grade | 7 (Slowest) | 8 (Fastest) | Speed grade affects maximum operating frequency and timing closure; a slower device may not meet timing, while a faster one may be overkill. |
| Number of PLLs | 2 | 2 | PLLs are needed for clock synthesis and management; matching PLL count ensures clocking architectures remain compatible. |
| Embedded Multipliers (18x18) | 126 | 288 | 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 10CL040YF484I7G and the 10CL080YF484C8G?
The primary differences are logic density, speed grade, and operating temperature range. The 10CL040YF484I7G is a Cyclone 10 LP device with 40,000 logic elements, a speed grade of 7, and an industrial temperature range. The 10CL080YF484C8G offers 80,000 logic elements, a speed grade of 8, and a commercial temperature range. Both use the same 484-pin FBGA package.
Are the 10CL040YF484I7G and 10CL080YF484C8G pin-to-pin compatible?
Yes, both devices are offered in the same 484-pin FineLine BGA (FBGA) package with identical pinouts as defined by Intel (Altera) for the Cyclone 10 LP family. However, designers must verify that all power, ground, and I/O assignments meet the specific requirements of each density and speed grade before substituting one for the other.
Can the 10CL040YF484I7G be used as a direct drop-in replacement for the 10CL080YF484C8G?
No, a direct drop-in replacement is not possible without design changes. The 10CL080YF484C8G has twice the logic density and a different speed grade, which affects timing closure, power consumption, and configuration bitstream. The 10CL040YF484I7G also has an industrial temperature range, while the 10CL080YF484C8G is commercial. The configuration file for one device is not compatible with the other.
What are the operating temperature ranges for these two devices?
The 10CL040YF484I7G is rated for industrial temperature range (I7), typically -40°C to +100°C junction temperature. The 10CL080YF484C8G is rated for commercial temperature range (C8), typically 0°C to +85°C junction temperature. These ranges are specified in the respective Intel Cyclone 10 LP device datasheets.
Do both devices support the same configuration schemes?
Yes, both the 10CL040YF484I7G and 10CL080YF484C8G support the same configuration schemes as part of the Cyclone 10 LP family, including active serial (AS), passive serial (PS), JTAG, and active parallel (AP) configuration modes. However, the configuration bitstream size differs between the 40K and 80K logic element densities.
What is the difference in logic elements and embedded memory between these two FPGAs?
The 10CL040YF484I7G contains 40,000 logic elements and 1,134 Kbits of embedded memory. The 10CL080YF484C8G contains 80,000 logic elements and 2,754 Kbits of embedded memory. These parameters are verified from the Intel Cyclone 10 LP device overview and datasheet.
Are the speed grades of these two devices interchangeable in terms of timing performance?
No, the speed grades are not interchangeable. The 10CL040YF484I7G has a speed grade of 7, while the 10CL080YF484C8G has a speed grade of 8. A lower speed grade number indicates faster performance in Intel FPGA nomenclature. Therefore, the 10CL040YF484I7G (grade 7) is faster than the 10CL080YF484C8G (grade 8). Timing analysis must be re-run if substituting one for the other.
Which device is more suitable for power-sensitive industrial applications?
The 10CL040YF484I7G is more suitable for industrial applications due to its industrial temperature range (-40°C to +100°C junction). The 10CL080YF484C8G is rated for commercial temperatures (0°C to +85°C junction) and is not specified for industrial environments. However, the 10CL080YF484C8G offers higher logic density for applications requiring more resources in commercial settings.
