10CL040YU484C8G vs 10CL080YU484C8G

The primary difference is logic density. The 10CL040YU484C8G is a Cyclone 10 LP FPGA with 40,000 logic elements (LEs), while the 10CL080YU484C8G offers 80,000 LEs. Both devices are in the same 484-pin UBGA package (484-ball Ultra FineLine BGA) and share the same speed grade (8) and commercial temperature range, but the 10CL080YU484C8G provides approximately twice the logic capacity, more embedded memory, and additional multiplier resources compared to the 10CL040YU484C8G.

Yes, both devices are offered in the same 484-pin UBGA package (package code U484). However, pin compatibility does not guarantee functional equivalence. The 10CL080YU484C8G may use additional I/O pins or power pins that are not connected or have different functions on the 10CL040YU484C8G. A detailed pinout comparison using the respective device pinout files from Intel (Altera) is required before considering a board-level swap.

Not directly without design changes. Although the package is identical, the 10CL080YU484C8G has a different logic capacity, embedded memory blocks, and possibly different I/O bank assignments. The FPGA configuration bitstream is also device-specific. A redesign, recompilation, and revalidation of the configuration file are mandatory. Additionally, power supply requirements and decoupling may differ. Always consult the Intel Cyclone 10 LP device datasheet and pinout files for both devices.

Both the 10CL040YU484C8G and 10CL080YU484C8G are Cyclone 10 LP FPGAs and support the same configuration schemes, including active serial (AS), passive serial (PS), fast passive parallel (FPP), and JTAG. However, the configuration file size differs because of the different logic densities. The 10CL080YU484C8G requires a larger configuration bitstream, so the external configuration memory size must be adjusted accordingly.

According to Intel Cyclone 10 LP device specifications, the 10CL040YU484C8G provides 1,134 Kbits of embedded memory and 126 embedded 18x18 multipliers. The 10CL080YU484C8G provides 2,544 Kbits of embedded memory and 252 embedded 18x18 multipliers. These differences directly affect DSP performance and memory-intensive applications, so the choice depends on the required processing and buffering capacity.

Yes. Both the 10CL040YU484C8G and 10CL080YU484C8G use speed grade 8 and are specified for commercial temperature range (0°C to 85°C junction temperature). The suffix "C8G" indicates commercial temperature, speed grade 8, and lead-free/RoHS-compliant packaging. These parameters are identical for both devices, so timing performance differences arise only from the logic density and routing architecture.

Selection depends on resource utilization. If the design fits within 40,000 LEs, 1,134 Kbits of memory, and 126 multipliers, the 10CL040YU484C8G is sufficient and may offer lower cost and power. If the design approaches or exceeds these limits, or if future expansion is expected, the 10CL080YU484C8G provides headroom with 80,000 LEs, 2,544 Kbits of memory, and 252 multipliers. Both are in the same package, so migration is possible with a recompiled bitstream and board verification.

Both devices are Cyclone 10 LP FPGAs and share the same nominal power supply rails: VCCINT (1.2 V), VCCIO (1.2 V to 3.3 V depending on I/O standard), and VCCA (2.5 V or 3.3 V for PLL analog supply). However, the total current consumption differs because the 10CL080YU484C8G has more logic and memory resources, resulting in higher dynamic power. Power estimation should be performed using Intel's Early Power Estimator (EPE) or PowerPlay Power Analyzer for each specific design.
