Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range (0°C to +70°C). Confirm the package type matches the required footprint. Check RoHS compliance status as manufacturing processes may vary by production date. Ensure design files support the 256-pin FBGA outline.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells are required for moderate complexity designs. Compare against the LC4512V series if lower power consumption or higher speed (5 ns) is necessary. Verify that the 7.5 ns delay meets the system timing requirements. Consider the 256-pin package availability relative to board space constraints.
