72V265LA15TFI

FIFOs Memory Overview

The Renesas Electronics Corporation 72V265LA15TFI is a synchronous FIFO memory device belonging to the 72V series. It features a storage capacity of 288K bits, organized as 16K words by 18 bits. The component supports a data rate of 66.7MHz with an access time of 10ns. It operates on a single power supply voltage ranging from 3V to 3.6V and draws a maximum supply current of 55mA. The device utilizes a 64-pin TQFP package measuring 10x10mm and functions within an industrial temperature range of -40°C to +85°C.

FIFOs Memory Feature Summary

• Supports independent read and write clocks, allowing simultaneous reading and writing operations.
• Features programmable Almost-Empty and Almost-Full flags for flexible status signaling.
• Includes retransmit operation capability with fixed, low first word data latency.
• Provides auto power down functionality to minimize standby power consumption.

FIFOs Memory Applications

• Networking applications requiring large data buffering
• Video processing systems
• Telecommunications equipment
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as TFGI8 or PFI8 exist within the same family. Confirm RoHS compliance status, as specific suffixes may differ in environmental certification. Check for End-of-Life notices, as certain variants have been discontinued. Ensure the selected package matches the required PCB footprint specifications.

FIFOs Memory Selection Notes

Select this component when a uni-directional synchronous FIFO with 18-bit width is required. It serves as a functionally compatible replacement for the 5V 722x5 family while operating at lower voltages. Consider the 10ns cycle time and 66.7MHz speed for high-throughput buffering needs. Verify that the 64-pin TQFP package fits the design constraints.

FIFOs Memory Part Context

This part belongs to the IDT/Renesas SuperSync FIFO family, designed for low-power 3.3V applications. It replaces older 5V logic families with improved performance metrics. The 72V265 variant specifically offers 16K x 18 organization. The product line targets high-speed data synchronization between asynchronous domains.

FIFOs Memory Replacement Considerations

The 72V265LA10PFG is a pin-compatible alternative within the same family. Other variants like 72V265LA15TFGI8 share similar electrical characteristics but may differ in packaging or compliance status. Verify functional compatibility before substitution.
