FIFOs Memory Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution channels indicate limited availability or discontinuation. Verify current stock status and lead times with authorized suppliers before design finalization. Consider alternative sourcing strategies due to potential obsolescence constraints.

FIFOs Memory Selection Notes

Select this part for applications requiring high-density synchronous FIFO buffering with specific 36-bit word widths. Ensure system requirements align with the 3.3V operating voltage and 144-pin BGA footprint. Evaluate thermal management needs given the surface mount packaging. Confirm that the 166 MHz maximum frequency meets the target interface speed requirements.

FIFOs Memory Part Context

The 72V3640L6BB8 belongs to the SUPER SYNC II family of synchronous FIFOs originally developed by IDT and continued by Renesas. This series is characterized by high performance and low power consumption. The component serves as a specialized memory buffer for digital signal processing and communication interfaces.

FIFOs Memory Replacement Considerations

Verify cross-reference compatibility with IDT72V3640L6BB8 variants. Check for pin-compatible alternatives within the 72V36xx series if functional equivalence is required.
