Configuration PROMs For FPGAs Procurement Notes

Verify the specific package variant, as datasheets may list both BQFP and PQFP options for this part number. Confirm that the design supports the required 3V to 3.6V operating voltage range. Check for RoHS compliance status, as older production runs may differ from current specifications. Ensure the PCB footprint matches the 100-pin QFP outline provided in the official mechanical drawings.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 4 Mbit configuration capacity is sufficient for the target FPGA device. Consider the 100-pin QFP package constraints regarding board space and thermal management. Verify compatibility with the specific FPGA family being used, as pin assignments and timing requirements vary between devices. Evaluate the need for system-in-programmability versus one-time programmable alternatives based on update frequency.
