Field Programmable Gate Array Procurement Notes

This component is identified as an End-of-Life (EOL) product. Verification of current availability requires checking authorized distributors or secondary market suppliers, as original manufacturer production has ceased. Ensure compliance with RoHS directives if applicable to the specific revision, though standard FLEX 8000 devices may not be RoHS compliant.

Field Programmable Gate Array Selection Notes

Select this device when a high-density PLD with 5.0 V operation is required. It is suitable for applications needing in-circuit reconfigurability and support for legacy 5.0 V systems. Designers should utilize the MAX+PLUS II development system for compilation and place-and-route. Consider the A-2 speed grade performance metrics for timing analysis.

Field Programmable Gate Array Part Context

The EPF8820A is part of the FLEX 8000 series, which bridges EPLD and FPGA characteristics. It offers fine-grained architecture with high register counts. The 'TC144' suffix indicates a Thin Quad Flat Pack package with 144 pins. The '-2' suffix denotes the A-2 speed grade, providing specific timing performance characteristics for the device.

Field Programmable Gate Array Replacement Considerations

As an obsolete component, direct replacements are limited. Modern equivalents from Intel/Altera include Cyclone or Stratix families, though these require significant architectural redesign and voltage level adjustments. Legacy design files must be migrated to Quartus Prime software for implementation on newer hardware.
