Field Programmable Gate Array Procurement Notes

Verify the specific suffix code against official datasheets to confirm temperature range and package variations. Confirm RoHS compliance status as it varies by manufacturing date and region. Check for export control classifications such as ECCN 3A991D before international transactions. Ensure compatibility with existing PCB footprints for the 256-LBGA package.

Field Programmable Gate Array Selection Notes

Select this model when nonvolatile storage is required to eliminate external configuration devices. Compare gate density and I/O count against lower-tier models like the A3P060 or higher-tier variants within the ProASIC3 family. Evaluate power consumption requirements against the 1.5 V core voltage specifications. Verify that the 350 MHz maximum frequency meets the target application timing constraints.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 Flash family, which bridges the gap between ASICs and standard FPGAs by offering instant-on functionality. It shares pin-compatible packages with other members of the series, facilitating design scalability across different capacity tiers while maintaining consistent physical integration parameters.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements include other ProASIC3 Flash devices such as the A3P1000-1FG256 or A3P1000-2FG256, depending on speed grade requirements. Cross-family migration to SmartFusion or IGLOO may be necessary if ARM processor integration or lower power consumption is prioritized over pure logic density.
