Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +100°C). Confirm the 381-pin CABGA package dimensions match the PCB footprint requirements. Ensure compatibility with Lattice Diamond software for design implementation and programming.

Field Programmable Gate Array Selection Notes

Select this model when 22,000 ALMs and 1.9 Mbit memory are sufficient for the logic density requirements. Consider the 3.2 Gb/s SERDES capability if serial interface bandwidth is needed. Compare against the LFE5U-45 variant if industrial temperature rating is not required, or the LFE5UM-85 variant if higher logic capacity is necessary.

Field Programmable Gate Array Part Context

This component belongs to the Lattice ECP5 Ultra Medium family, which utilizes 40 nm technology. The series is characterized by its balance of performance and power efficiency, targeting applications requiring moderate logic resources with high-speed serial capabilities.

Field Programmable Gate Array Replacement Considerations

The LFE5UM-85F-7BG381I offers pin-compatible migration with increased logic resources (42,000 ALMs). Designers may also consider the LFE5U-45F-7BG381I if the industrial temperature range is not mandatory.
