Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +100°C) against the official datasheet. Confirm the 381-CABGA package dimensions and pinout match the design requirements. Ensure compatibility with Lattice Diamond software versions supporting the ECP5 UltraPlus family before finalizing procurement.

Field Programmable Gate Array Selection Notes

Select this model when designs require SERDES capabilities within the 85K logic density class. Compare against the non-SERDES variant LFE5U-85F if high-speed serial interfaces are unnecessary. Verify that the 381-pin footprint accommodates the PCB layout constraints and thermal management needs for the specified operating temperature range.
