72265LA15TFI

Overview

The Renesas Electronics Corporation 72265LA15TFI is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 288K bits, organized as 16K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP (10x10) surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports First Word Fall Through (FWFT) functionality for reduced latency
• Includes programmable Almost-Empty and Almost-Full flags for status monitoring
• Features auto power-down mode to minimize standby power consumption
• Provides retransmit operation capability with fixed low first word data latency

Applications

• Networking equipment requiring large data buffering
• Video processing systems needing high-speed data handling
• Telecommunications infrastructure applications
• General-purpose data communications interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity level (MSL 3) handling precautions during assembly. Ensure replacement strategies are in place given the discontinued manufacturing status.

Selection Notes

Select this component when 18-bit wide synchronous FIFO buffering is required at 66.7MHz speeds. The 72265LA15TFI is suitable for designs operating on standard 5V logic levels. Consider its pin compatibility with other members of the 722x5 family if system upgrades are planned. Evaluate the 64-TQFP package constraints against available PCB real estate.

Part Context

This part belongs to the IDT 7200 series of SuperSync FIFOs, designed for high-performance data buffering. It serves as a functionally compatible version of earlier models but operates specifically on 5V supplies. The series is engineered for applications demanding reliable synchronization between asynchronous clock domains without complex handshaking protocols.
