Key electrical and mechanical differences between the two devices
| Parameter | 10CL040YU484I7G | 10CL040YU484C8G | Why it matters |
|---|---|---|---|
| Operating Temperature Range | -40°C to +100°C (Industrial) | 0°C to +85°C (Commercial) | Determines the environments in which the device can reliably operate; industrial-grade parts support wider temperature extremes than commercial-grade parts. |
| Speed Grade | 7 (faster) | 8 (slower) | Speed grade affects maximum operating frequency and timing closure; a faster grade can meet tighter timing requirements but may cost more. |
| Family | Cyclone 10 LP | Cyclone 10 LP | Same device family ensures identical architecture, IP compatibility, and tool support. |
| Logic Elements (LEs) | 39,600 | 39,600 | Logic capacity determines the complexity of designs the FPGA can implement; identical LE counts mean equivalent logic resources. |
| Package | 484-pin UBGA | 484-pin UBGA | Package type and pin count must match for PCB footprint and pinout compatibility. |
| Supply Voltage | 1.2 V core | 1.2 V core | Core voltage must match the board power design; identical values allow drop-in replacement without power redesign. |
| Embedded Memory | 1,161 kbit | 1,161 kbit | On-chip memory capacity affects buffering and storage capabilities within the FPGA fabric. |
| Number of I/O Pins | 325 | 325 | I/O count determines how many external signals the device can interface with; identical counts preserve system connectivity. |
| Embedded Multipliers (18x18) | 126 | 126 | Hard multiplier blocks are essential for DSP and arithmetic functions; identical counts ensure equivalent DSP performance. |

Frequently asked questions
What are the key differences between the 10CL040YU484I7G and 10CL040YU484C8G?
The primary difference is the speed grade and operating temperature range. The 10CL040YU484I7G is specified with a speed grade of 7 and an industrial temperature range (I), while the 10CL040YU484C8G is specified with a speed grade of 8 and a commercial temperature range (C). Both devices are Intel (formerly Altera) Cyclone 10 LP FPGAs with 40,000 logic elements in a 484-pin UBGA package.
Are the 10CL040YU484I7G and 10CL040YU484C8G pin-to-pin compatible?
Yes. Both devices share the same package designation (U484, 484-pin UBGA) and the same device family and logic density (10CL040). The pinout and package footprint are identical, so they are pin-to-pin compatible. However, the speed grade and temperature grade differences must be validated for the target application.
What is the difference in speed grade between the 10CL040YU484I7G and 10CL040YU484C8G?
The 10CL040YU484I7G has a speed grade of 7, and the 10CL040YU484C8G has a speed grade of 8. In Intel Cyclone 10 LP ordering codes, a lower speed grade number indicates a faster device. Therefore, the speed grade 7 device offers higher performance than the speed grade 8 device.
What are the operating temperature ranges for the 10CL040YU484I7G and 10CL040YU484C8G?
The 10CL040YU484I7G is rated for the industrial temperature range, typically -40°C to +100°C junction temperature (TJ). The 10CL040YU484C8G is rated for the commercial temperature range, typically 0°C to +85°C junction temperature (TJ). These ranges are defined in the Intel Cyclone 10 LP device datasheet.
Can the 10CL040YU484C8G be used as a drop-in replacement for the 10CL040YU484I7G?
Not directly. Although the package and pinout are identical, the 10CL040YU484C8G has a slower speed grade (8 vs. 7) and a narrower commercial temperature range (0°C to +85°C vs. -40°C to +100°C). A drop-in replacement is only possible if the target design meets the timing requirements at speed grade 8 and operates within the commercial temperature range.
Do both the 10CL040YU484I7G and 10CL040YU484C8G have the same logic density and package?
Yes. Both are Cyclone 10 LP devices with 40,000 logic elements (LEs) and are housed in the same 484-pin UBGA package (U484). The logic fabric, memory blocks, and embedded multipliers are identical; only the speed grade and temperature grade differ.
Which device is more suitable for industrial applications, the 10CL040YU484I7G or the 10CL040YU484C8G?
The 10CL040YU484I7G is more suitable for industrial applications because it is rated for the industrial temperature range (-40°C to +100°C TJ) and offers a faster speed grade (7). The 10CL040YU484C8G is intended for commercial applications within 0°C to +85°C TJ and may not meet industrial environmental or timing requirements.
Are the 10CL040YU484I7G and 10CL040YU484C8G RoHS compliant?
Yes. Both devices are offered in RoHS-compliant packages as part of Intel's Cyclone 10 LP family. However, always verify the specific ordering code and any applicable exemptions or lead-free status in the Intel product catalog or the manufacturer's official datasheet before finalizing a design.
