Key electrical and mechanical differences between the two devices
| Parameter | 10CL080YU484I7G | 10CL055YF484C8G | Why it matters |
|---|---|---|---|
| Logic Elements (LEs) | 80,000 | 55,000 | Logic capacity determines how much custom digital logic can be implemented; a smaller device may not fit the same design. |
| Total RAM Bits | 2,810,880 | 2,396,160 | Embedded memory affects buffering, FIFO depth, and data storage capability within the FPGA fabric. |
| Number of I/Os | 278 | 278 | I/O count determines how many external signals and peripherals the device can interface with. |
| Package / Case | 484-FBGA (23x23) | 484-FBGA (23x23) | Package compatibility is essential for board-level drop-in replacement and thermal/mechanical fit. |
| Operating Temperature Range | -40°C to 100°C (TJ) | 0°C to 85°C (TJ) | Industrial temperature grades support harsher environments, while commercial grades are limited to benign conditions. |
| Speed Grade | 7 (Fastest) | 8 (Slowest) | Speed grade affects maximum operating frequency and timing closure; a slower grade may not meet performance targets. |
| Supply Voltage - Core | 1.2 V | 1.2 V | Core voltage must match the board power design; mismatches can damage the device or prevent operation. |
| Number of PLLs | 4 | 4 | PLLs provide clock synthesis and phase shifting; insufficient PLLs limit clocking flexibility. |
| Maximum Operating Frequency | 450 MHz | 400 MHz | Maximum frequency determines achievable system performance and timing margins for high-speed designs. |
| RoHS Status | RoHS Compliant | RoHS Compliant | RoHS compliance is required for sale in many regions and affects manufacturing and disposal regulations. |

Frequently asked questions
What are the key differences between the 10CL080YU484I7G and the 10CL055YF484C8G?
The 10CL080YU484I7G is an Intel (Altera) Cyclone 10 LP FPGA with 80,000 logic elements in a 484-pin UBGA package, rated for industrial temperature grade (I7 speed grade). The 10CL055YF484C8G is a Cyclone 10 LP FPGA with 55,000 logic elements in a 484-pin FBGA package, rated for commercial temperature grade (C8 speed grade). They differ in logic density, package type, and speed/temperature grade.
Are the 10CL080YU484I7G and 10CL055YF484C8G pin-to-pin compatible?
No. The 10CL080YU484I7G uses a 484-pin UBGA (Ultra FineLine BGA) package, while the 10CL055YF484C8G uses a 484-pin FBGA (FineLine BGA) package. These are different package technologies with different ball pitches and PCB land patterns, so they are not pin-to-pin compatible.
Can the 10CL055YF484C8G be used as a direct drop-in replacement for the 10CL080YU484I7G?
No. Beyond the package incompatibility, the 10CL080YU484I7G offers 80,000 logic elements versus 55,000 in the 10CL055YF484C8G, and the industrial temperature grade (I7) differs from the commercial grade (C8). A direct drop-in replacement is not possible without design and PCB changes.
What are the operating temperature ranges for these two FPGAs?
The 10CL080YU484I7G is specified for the industrial temperature grade, typically -40°C to +100°C junction temperature (TJ). The 10CL055YF484C8G is specified for the commercial temperature grade, typically 0°C to +85°C junction temperature (TJ). Designers must verify exact thermal limits in the respective Intel Cyclone 10 LP datasheets.
Do both devices belong to the same FPGA family?
Yes. Both the 10CL080YU484I7G and the 10CL055YF484C8G are members of the Intel (Altera) Cyclone 10 LP FPGA family, which targets low-cost, low-power logic applications.
Which device offers higher logic density, and by how much?
The 10CL080YU484I7G offers higher logic density with 80,000 logic elements (LEs), compared to 55,000 LEs in the 10CL055YF484C8G. This represents approximately 45% more logic capacity in the 10CL080YU484I7G.
Are the speed grades of these two devices equivalent?
No. The 10CL080YU484I7G carries speed grade 7 (I7), while the 10CL055YF484C8G carries speed grade 8 (C8). In Intel Cyclone 10 LP nomenclature, a lower speed grade number generally indicates faster performance. Therefore, the 10CL080YU484I7G (grade 7) is the faster speed grade of the two.
What configuration options do these Cyclone 10 LP devices support?
Both the 10CL080YU484I7G and 10CL055YF484C8G support standard Cyclone 10 LP configuration schemes, including active serial (AS), passive serial (PS), JTAG, and configuration via external flash or CPLD. Exact configuration voltage and flash density requirements should be confirmed in the Intel Cyclone 10 LP device datasheet.
