Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'V' indicates the correct speed grade and voltage variant as per the official datasheet. Confirm package type is TQFP-176. Check RoHS compliance status as older revisions may differ. Ensure the supplier provides genuine Lattice Semiconductor products to avoid counterfeit risks. Validate that the component meets the required temperature range specifications for your application environment.

Complex Programmable Logic Devices Selection Notes

Select this device when 384 macrocells are sufficient for complex logic functions requiring high speed. Consider the 176-pin TQFP package if board space allows for larger footprints compared to BGA options. Evaluate power consumption requirements against the family's low-power characteristics. Compare pin counts and I/O flexibility with smaller or larger devices in the same family to ensure optimal resource utilization.
