72265LA15PF

Overview

The Renesas Electronics Corporation 72265LA15PF is a SuperSync synchronous FIFO memory device with a storage capacity of 16K x 18 bits. It operates on a 3.3V supply voltage and supports data rates up to 66.7MHz with a 10ns read/write cycle time. The component features independent read and write clocks, programmable flags, and auto power-down capabilities. It is housed in a 64-pin TQFP package.

Feature Summary

• SuperSync architecture enabling simultaneous independent read and write operations via separate clock inputs.
• Fixed low first word data latency for efficient retransmit operation.
• Programmable Almost-Empty and Almost-Full status flags for precise buffer management.
• Auto power-down functionality designed to minimize standby power consumption.

Applications

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

Procurement Notes

Verify the specific suffix 'PF' against official Renesas documentation to confirm the exact package type and temperature grade. Confirm RoHS compliance status as older variants may differ. Check current product lifecycle status as this series may be discontinued or subject to last-time buy notifications. Ensure design-in compatibility with 3.3V logic levels.

Selection Notes

Select this component when a 3.3V synchronous FIFO with 18-bit width is required. It serves as a functionally compatible replacement for the 5V 72265 family while offering lower power consumption. Consider the 64-pin TQFP footprint during PCB layout. Verify that the 10ns access time meets system timing requirements for the target application speed.

Part Context

This part belongs to the Renesas 72V2x5 SuperSync FIFO family. These devices are engineered for high-performance buffering in applications demanding large data throughput. The 72265LA15PF specifically adapts the standard 72265 functionality for 3.3V operation, removing the Frequency Select pin to simplify clocking configurations compared to its 5V predecessors.

Replacement Considerations

The 72265LA15PF is functionally compatible with the 5V 72265 family. Designers should verify voltage level tolerances when replacing 5V components with this 3.3V variant. No direct public substitute part numbers are confirmed in the provided source material.
