Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix (-3, -4, or -5) required for timing constraints, as the base part number does not specify performance tier. Confirm industrial temperature rating compliance (-40°C to +85°C) matches system requirements. Check current lifecycle status, as older FPGA families may face obsolescence risks. Ensure ESD handling protocols are followed during installation due to the fine-pitch BGA packaging.

Field Programmable Gate Array Selection Notes

Select this component when designs require approximately 90k logic elements and significant embedded memory resources. Verify that the 780-pin FBGA footprint fits the board layout constraints. Compare against EP2S60 or EP2S130 if density adjustments are needed for vertical migration within the same package family. Ensure the chosen speed grade meets the maximum clock frequency requirements of the target application.

Field Programmable Gate Array Part Context

This device belongs to the Stratix II family, which introduced the Adaptive Logic Module (ALM) architecture to improve logic utilization efficiency compared to previous generations. It serves as a mid-range solution within the series, bridging the gap between the EP2S60 and EP2S130 densities while offering comparable DSP and memory capabilities scaled to its size.

Field Programmable Gate Array Replacement Considerations

For pin-compatible upgrades within the same 780-pin package, consider the EP2S130F780 series for higher density. For legacy replacement, verify software compatibility with Quartus II versions supporting the Stratix II family.
