Field Programmable Gate Array Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability requires checking authorized distributors for remaining stock or surplus inventory. Engineers must confirm the authenticity of any available units through official supply chain channels to ensure reliability and compliance with quality standards before procurement.

Field Programmable Gate Array Selection Notes

Designers should evaluate alternative components within the same product family or newer generations due to the discontinuation status. Considerations include pin compatibility, logic density requirements, and power consumption profiles. Migration strategies should account for potential differences in toolchain support and packaging options when selecting replacement devices.

Field Programmable Gate Array Part Context

The XC3S400AN-4FG400I belongs to the Spartan-3AN series, which integrates non-volatile configuration memory directly on the chip. This architecture simplifies board design by eliminating external configuration flash devices. The part represents a mid-range solution within the family, balancing performance and cost for general-purpose programmable logic applications.
