FIFOs Memory Procurement Notes

This component is officially classified as obsolete by the manufacturer. Verification of availability should focus on surplus distributors rather than direct manufacturing channels. Confirm RoHS compliance status, as the product does not meet current RoHS specifications. Ensure compatibility with existing system designs due to discontinued production status.

FIFOs Memory Selection Notes

Select this part for legacy systems requiring specific TeraSync interface characteristics. Verify that the 144-PBGA footprint matches the target PCB design. Consider the limited operating voltage window and commercial temperature grade when evaluating environmental suitability. Assess alternative components if new production is required.

FIFOs Memory Part Context

The 72T series represents Renesas' TeraSync family of FIFO memories designed for high-performance data handling. This specific model integrates asynchronous and synchronous modes to accommodate various system timing requirements. It serves as a specialized buffer solution for bridging speed mismatches in complex electronic architectures.

FIFOs Memory Replacement Considerations

As an obsolete part, no direct official substitutes are listed. Engineers must evaluate pin-compatible alternatives from other manufacturers or redesign using modern FIFO equivalents. Verify functional equivalence regarding access times and bus width configurations during migration.
