72V261LA15TF8

FIFOs Memory Overview

The 72V261LA15TF8 is a synchronous FIFO manufactured by Renesas Electronics Corporation, housed in a 64-TQFP package. It provides a storage capacity of 144K bits, organized as 16K words by 9 bits. The device supports a data rate of 66.7MHz with an access time of 10ns. It operates on a supply voltage ranging from 3V to 3.6V and draws a maximum current of 55mA. The component functions as a unidirectional memory buffer and includes support for First Word Fall Through (FWFT) and programmable flags.

FIFOs Memory Feature Summary

• Supports synchronous operation with independent read and write clocks to permit simultaneous data handling.
• Includes programmable Almost-Empty and Almost-Full flags alongside standard status indicators.
• Features auto power down capability to minimize standby power consumption.
• Offers retransmit operation with fixed, low first word data latency.

FIFOs Memory Applications

• Networking data buffering
• Video signal processing
• Telecommunications systems

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 approved upgrade alternatives. Confirm that the replacement part meets all original electrical and pinout specifications before integration into existing designs.

FIFOs Memory Selection Notes

Select this component only if legacy compatibility with the 72V261 family is required. Verify that the 64-TQFP package fits the target PCB layout. Ensure the design accounts for the discontinuation status and identifies a suitable upgrade path, such as the 72V261LA10TFG8, which maintains functional compatibility.

FIFOs Memory Part Context

The 72V261LA15TF8 belongs to the 72V SuperSync FIFO series, designed for high-speed data buffering applications. It serves as a 3.3V version of the older 5V 722x1 family, offering improved power efficiency while maintaining functional compatibility. The device is intended for use in systems requiring reliable, high-throughput temporary data storage.

FIFOs Memory Replacement Considerations

The 72V261LA10TFG8 is listed as an upgrade alternative. Verify pin compatibility and electrical parameters before substitution.
