Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as this part number may be subject to end-of-life status. Confirm that the specific ordering suffix matches the required package type and temperature range. Ensure compatibility with existing design tools and verify that the EEPROM endurance specifications meet long-term deployment requirements.

Complex Programmable Logic Devices Selection Notes

Select this model when a 5-V supply is required alongside moderate logic density. The 10 ns speed grade offers a balance between performance and power consumption compared to faster grades. Consider the TQFP-44 package constraints for PCB layout. Verify that the 64 macrocell count suffices for the target logic complexity without requiring multiple devices.
