• Clock domain crossing interfaces
• Data acquisition system storage

FIFOs Memory Procurement Notes

This component is officially discontinued by the manufacturer. Verify end-of-life status through official Renesas channels before design finalization. Check for valid replacement part numbers or alternative suppliers if current stock is required for maintenance purposes.

FIFOs Memory Selection Notes

Select this part for applications requiring 3.3V operation with specific 128K x 9 depth. Ensure compatibility with existing SuperSync designs. Consider pin-compatible alternatives within the 72V2x1 family if availability is critical.

FIFOs Memory Part Context

Part of the 72V291 SuperSync FIFO series designed for low-power 3.3V applications. Functionally compatible with older 5V 72291 devices but optimized for modern voltage levels. Eliminates variable clock cycle counting delays found in previous generations.
