Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix '1' corresponds to the required timing performance for your design. Confirm that the FG484 package dimensions match your PCB footprint constraints. Ensure the industrial temperature rating meets your environmental operating conditions. Check current availability status as flash FPGA production may be limited.

Field Programmable Gate Array Selection Notes

Select this device if your design requires nonvolatile configuration storage to eliminate external memory components. Consider the 400K gate density and 194 available user I/Os for medium-complexity logic applications. Evaluate the power consumption benefits of flash technology compared to SRAM-based FPGAs for battery-operated systems.

Field Programmable Gate Array Part Context

This part belongs to the ProASIC3 Flash family, which bridges the gap between CPLDs and high-density FPGAs. It offers ASIC-level unit costs with FPGA reprogrammability. The family is known for its security features and low power consumption, making it suitable for cost-sensitive applications where instant-on capability is critical.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package are not explicitly listed for this specific speed grade. Higher density devices like the A3P600 or A3P1000 in FG484 packages may offer functional upgrades but require design verification for routing and resource utilization compatibility.
