72V261LA15TF

FIFOs Memory Overview

The Renesas Electronics Corporation 72V261LA15TF is a synchronous FIFO memory integrated circuit belonging to the 72V series. It provides a storage capacity of 144K bits, organized as 16K words by 9 bits. The device supports unidirectional data transfer with a maximum clock frequency of 66.7MHz and an access time of 10ns. It operates on a single power supply voltage ranging from 3V to 3.6V, with a maximum supply current of 55mA. The component is housed in a 64-pin TQFP package measuring 14x14mm and is designed for surface mount installation.

FIFOs Memory Feature Summary

• Supports programmable Almost-Empty and Almost-Full flags for precise buffer management
• Enables retransmit operation with fixed, low first word data latency time
• Features independent read and write clocks allowing simultaneous operations
• Includes auto power down functionality to minimize standby power consumption

FIFOs Memory Applications

• Networking equipment requiring large data buffering
• Video processing systems needing high-speed data handling
• Telecommunications infrastructure utilizing SuperSync FIFO technology
• Data communications interfaces demanding reliable synchronization

FIFOs Memory Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm moisture sensitivity level (MSL 3) requirements for storage and handling. Check RoHS compliance documentation as the part may not meet current environmental standards. Validate pin compatibility with existing PCB layouts before integration.

FIFOs Memory Selection Notes

Select this component when a 16K x 9 synchronous FIFO is required within the 72V family. Ensure system voltage aligns with the 3V to 3.6V operating range. Consider the 64-TQFP package dimensions for board space constraints. Evaluate if the 66.7MHz speed meets interface timing requirements compared to faster alternatives.

FIFOs Memory Part Context

This part belongs to the Renesas 72V SuperSync FIFO family, which offers functionally compatible versions of older 5V parts adapted for 3.3V operation. The 72V261 variant specifically targets applications needing 9-bit wide data paths. It shares architectural similarities with other members like the 72V271 and 72V281, differing primarily in memory depth and bus width configurations.

FIFOs Memory Replacement Considerations

Check for available tray packaging options such as 72V261LA15PF if reel quantities are unavailable. Verify functional equivalence with IDT72V261LA15 variants for direct substitution. Confirm that any replacement maintains the same 64-pin TQFP footprint and electrical specifications.
