72V3643L15PF

FIFOs Memory Overview

The 72V3643L15PF is a synchronous FIFO manufactured by Renesas Electronics, featuring a storage capacity of 1K x 36 bits. It operates within a supply voltage range of 3 V to 3.6 V and supports data rates up to 66.7 MHz with an access time of 10 ns. The component utilizes a 128-pin TQFP package and includes programmable flags for status monitoring.

FIFOs Memory Feature Summary

• Supports bidirectional data transfer between independent clock domains
• Features programmable Almost-Full and Almost-Empty status flags
• Includes First Word Fall Through (FWFT) timing mode support

FIFOs Memory Applications

• Buffering data streams in high-speed digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Network equipment packet buffering applications

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability requires checking authorized distributors for remaining stock or identifying qualified replacement parts from the same manufacturer family. Ensure compliance with RoHS directives as the standard version does not meet current environmental regulations.

FIFOs Memory Selection Notes

Select this part for designs requiring a 36-bit wide synchronous FIFO with 1K depth. Verify that the 3.3V operating voltage aligns with system power rails. Consider the 128-pin TQFP footprint during PCB layout. Evaluate alternative packages if higher density or different pin counts are required for the specific application constraints.

FIFOs Memory Part Context

Part of the 72V3643 series, this device belongs to Renesas' high-performance FIFO portfolio. It shares architectural similarities with other members like the 72V3643L10PF but differs in speed grade and package configuration. The series is designed for robust data buffering in complex electronic systems.

FIFOs Memory Replacement Considerations

Consider the 72V3643L15PF8 variant for reel packaging instead of trays. Other compatible options include the 72V3643L10PF for faster performance or the 723643L15PF8 for 5V operation requirements.
