Field Programmable Gate Array Procurement Notes

Verify the specific speed grade indicated by the '2' suffix, which denotes performance faster than standard variants. Confirm that the FG484 package dimensions align with your PCB footprint requirements. Ensure the industrial temperature rating meets your environmental specifications. Check current availability status as legacy flash FPGA lines may have limited production runs.

Field Programmable Gate Array Selection Notes

Select this device when nonvolatile configuration and immediate system startup are critical requirements. Consider the 400,000 gate capacity for moderate complexity designs needing low static power consumption. Evaluate the 194 available I/Os against your interface needs before choosing smaller packages like FG256 or larger densities like A3P600.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ProASIC3 Flash family, representing third-generation flash FPGA technology. It bridges the gap between CPLDs and high-density SRAM FPGAs by offering ASIC-like unit costs with FPGA reprogrammability. The family emphasizes security and instant-on capabilities for cost-sensitive applications.

Field Programmable Gate Array Replacement Considerations

For pin-compatible upgrades within the same package, consider the A3P600 or A3P1000 series devices. Higher density options provide increased logic resources while maintaining the FG484 footprint. Verify software toolchain compatibility if migrating to newer ProASIC3E or SmartFusion families.
