Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'B' against official Microchip/Microsemi documentation, as public records primarily list the '1CQ172GC' variant. Confirm RoHS compliance status, noting that similar ACT2 devices may not meet current environmental standards. Ensure the supplier provides valid traceability documents for this legacy component.

Field Programmable Gate Array Selection Notes

Select this component when a high number of logic resources is required in a ceramic CQFP package. Compare the 75 MHz speed grade against system timing requirements. Consider the 140 I/O count for interface needs. Evaluate alternative packages if lead-free compliance is mandatory, as older ACT2 series parts often lack full RoHS certification.

Field Programmable Gate Array Part Context

This FPGA belongs to the ACT2 family, a generation of high-performance PLDs known for their dense logic capacity and reliable ceramic construction. The A1280A model represents a specific density tier within this lineage, offering significant logic resources compared to lower-end variants while maintaining compatibility with established design tools for the architecture.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers for the A1280A-1CQ172B are not available in standard distributor databases. Designers should consult Microchip's official obsolescence notices or contact technical support for validated cross-reference recommendations for this legacy device.
