Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PLG84C' against official Microsemi documentation to confirm package type and temperature grade. Confirm end-of-life status or lifecycle availability through authorized distributors prior to procurement. Ensure compliance with export control classifications such as ECCN 3A991D if applicable to the destination region.

Field Programmable Gate Array Selection Notes

Select this component when a high-density, non-volatile FPGA solution is required for military or industrial applications. Compare against the A1240A-VQ176B for higher pin counts or the A1020B for lower density needs. Consider the 69 MHz performance limit relative to system clock requirements. Verify that the PLCC package footprint matches the target PCB design constraints.
