72V3640L7-5PFI

FIFOs Memory Overview

The 72V3640L7-5PFI is a SuperSync II synchronous FIFO manufactured by Renesas Electronics. It features a memory organization of 1K x 36 bits and operates with a maximum data rate of 133.3 MHz. The device supports a 3.3V supply voltage range from 3.15V to 3.45V and utilizes a 128-pin TQFP package. It includes programmable flags for status indication and supports First Word Fall Through functionality.

FIFOs Memory Feature Summary

• SuperSync II architecture enables independent read and write clock domains for simultaneous operations.
• First Word Fall Through (FWFT) capability provides fixed, low latency for the initial data word.
• Programmable Almost Full and Almost Empty flags allow precise buffer management.
• Retransmit operation ensures reliable data transfer with consistent first-word latency.

FIFOs Memory Applications

• High-speed network interface buffering
• Data acquisition system synchronization
• Video signal processing pipelines

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as specific variants may differ. Check moisture sensitivity level requirements for proper handling during assembly. Validate package dimensions against design specifications before integration.

FIFOs Memory Selection Notes

Select this component when bidirectional data flow is not required, as it is unidirectional. Ensure the 3.3V logic levels match the system interface. Consider the 128-pin footprint for PCB layout constraints. Verify that the 133.3 MHz speed meets the application timing requirements.

FIFOs Memory Part Context

This part belongs to the 72V36xx series of high-performance synchronous FIFOs. It shares functional similarities with other members like the 72V3641 but differs in directionality and speed grades. The series is designed for applications requiring large data buffers with precise control over data flow timing.

FIFOs Memory Replacement Considerations

The IDT72V3640L7-5PFI9 is listed as an alias or compatible variant. Verify pinout compatibility and electrical characteristics before substitution. Ensure the replacement supports the same 128-pin TQFP package and 3.3V operating voltage.
