Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'VC' against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as legacy documentation may vary. Check for End-of-Life notifications or alternative lead-free package options if required for new designs.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring guaranteed fixed timing up to 182 MHz without speed degradation from complex logic. Ensure the design fits within the 64 macrocell limit and utilizes the 32 available I/O pins. Verify that the 5-V operating voltage aligns with the target system power rails.

Complex Programmable Logic Devices Part Context
