Field Programmable Gate Array Procurement Notes

Verify the current lifecycle status before procurement as this specific part number is listed as obsolete or end-of-life in major distributor databases. Confirm availability through authorized Microchip channels or approved secondary markets. Ensure that any replacement components maintain compatibility with the original design specifications and regulatory requirements.

Field Programmable Gate Array Selection Notes

Select this component when a mid-range gate count FPGA with flash technology is required for cost-sensitive applications. Consider alternative packages such as VQFP or FBGA if pin density or thermal performance needs differ. Verify that the 231 MHz speed grade meets the timing requirements of the target digital logic design.

Field Programmable Gate Array Part Context

This device belongs to the ProASIC3 family, which bridges the gap between ASICs and standard FPGAs. It offers lower power consumption and smaller form factors compared to SRAM-based counterparts while retaining reprogrammability. The family is widely used in aerospace, defense, and industrial sectors for its radiation tolerance and long-term availability options.

Field Programmable Gate Array Replacement Considerations

Check for active equivalents within the ProASIC3 family, such as the A3P125-VQG100 or A3P125-FG144, depending on package preference. Review Microchip Product Change Notices for potential pin-compatible upgrades or next-generation replacements.
