Replacement verdict
Compatible functional replacement candidate
The 10CL080YU484I7G and 10CL040YF484C8G share the same 484-pin FineLine BGA footprint and Cyclone 10 LP device family, enabling a common board layout. However, they differ in logic density, speed grade, and operating temperature range, so the 10CL040YF484C8G is not a direct drop-in substitute for the 10CL080YU484I7G without design and timing revalidation.

Key electrical and mechanical differences between the two devices
| Parameter | 10CL080YU484I7G | 10CL040YF484C8G | Why it matters |
|---|---|---|---|
| Logic Elements (LEs) | 80,000 | 40,000 | LE count determines the amount of programmable logic available; a design that fits in the larger device may not fit in the smaller one, directly affecting functional substitutability. |
| Total RAM Bits | 2,810,880 | 1,161,216 | Embedded memory capacity limits on-chip buffering, FIFOs, and data storage; insufficient RAM prevents a design from being ported between the two devices. |
| Number of I/Os | 278 | 278 | Available user I/O pins determine how many external signals can be interfaced; matching counts support pin-compatible board designs. |
| Package / Case | 484-FBGA (23x23) | 484-FBGA (23x23) | Package footprint and ballout must match for a drop-in replacement on an existing PCB. |
| Operating Temperature Range | -40°C to 100°C (Industrial) | 0°C to 85°C (Commercial) | Temperature grade determines the environments in which the device can reliably operate; industrial and commercial parts are not interchangeable in harsh environments. |
| Speed Grade | 7 (Fastest) | 8 (Slowest) | Speed grade affects maximum operating frequency and timing closure; a slower grade may not meet the timing requirements of a design targeting the faster grade. |
| Supply Voltage | 1.2 V Core | 1.2 V Core | Core voltage must match the board power design; identical values allow the same power rails to be reused. |
| Number of PLLs | 4 | 4 | PLLs provide clock synthesis and management; matching counts support equivalent clocking architectures. |
| Embedded Multipliers (18x18) | 288 | 126 | Dedicated multipliers accelerate DSP functions; fewer multipliers can bottleneck arithmetic-intensive designs. |
| Maximum User Flash Memory | Not available | Not available | On-chip configuration flash affects boot behavior and external memory requirements; both devices lack user flash, so external configuration is required for both. |

Frequently asked questions
What are the key differences between the 10CL080YU484I7G and the 10CL040YF484C8G?
The 10CL080YU484I7G is an Intel (Altera) Cyclone 10 LP FPGA with 80,000 logic elements, a 484-pin UBGA package, and an industrial temperature grade of -40°C to 100°C (I7 speed grade). The 10CL040YF484C8G is a Cyclone 10 LP FPGA with 40,000 logic elements, a 484-pin FBGA package, and a commercial temperature grade of 0°C to 85°C (C8 speed grade). They differ in logic density, package type, temperature range, and speed grade.
Are the 10CL080YU484I7G and 10CL040YF484C8G pin-to-pin compatible?
No. The 10CL080YU484I7G uses a 484-pin UBGA (Ultra FineLine BGA) package, while the 10CL040YF484C8G uses a 484-pin FBGA (FineLine BGA) package. These are different package types with different ball pitches and PCB land patterns, so they are not pin-to-pin compatible.
Can the 10CL040YF484C8G be used as a direct drop-in replacement for the 10CL080YU484I7G?
No. Beyond the package incompatibility, the two devices have different logic densities (40K vs 80K logic elements), different speed grades (C8 vs I7), and different temperature ranges (commercial vs industrial). A direct drop-in replacement is not possible without redesigning the PCB and revalidating the design.
What temperature ranges do the 10CL080YU484I7G and 10CL040YF484C8G support?
The 10CL080YU484I7G supports the industrial temperature range of -40°C to 100°C (junction temperature). The 10CL040YF484C8G supports the commercial temperature range of 0°C to 85°C (junction temperature). The industrial-grade device is suitable for harsher environments, while the commercial-grade device is intended for standard operating conditions.
What are the logic element counts and equivalent logic densities of these two FPGAs?
The 10CL080YU484I7G contains 80,000 logic elements (LEs). The 10CL040YF484C8G contains 40,000 logic elements (LEs). The 10CL080YU484I7G offers twice the logic capacity of the 10CL040YF484C8G, making it suitable for more complex designs.
Do both devices belong to the same FPGA family and use the same configuration method?
Yes. Both the 10CL080YU484I7G and the 10CL040YF484C8G are members of the Intel (Altera) Cyclone 10 LP FPGA family. They both support configuration via active serial (AS), passive serial (PS), and JTAG modes, and they use the same configuration file formats (.sof, .pof, .rbf) within the Quartus Prime development environment.
What are the typical applications for each device given their differences?
The 10CL080YU484I7G, with its higher logic density and industrial temperature range, is typically used in industrial automation, motor control, and harsh-environment applications requiring more logic resources. The 10CL040YF484C8G, with lower density and commercial temperature range, is typically used in consumer electronics, office equipment, and standard commercial applications where cost and moderate logic capacity are priorities.
