72271LA15TFI

Overview

The Renesas Electronics Corporation 72271LA15TFI is a synchronous FIFO integrated circuit featuring a memory organization of 32K x 9 bits, totaling 288 Kbits. It operates with a maximum data rate of 66.7 MHz and an access time of 10 ns. The device supports a supply voltage range from 3 V to 3.6 V and draws a maximum supply current of 55 mA. It is housed in a 64-TQFP (10x10) surface-mount package.

Feature Summary

• Synchronous single-clock operation for reliable data transfer
• Programmable status flags including full and empty indicators
• Supports First-Word-Fall-Through (FWFT) mode for low-latency read access
• Unidirectional bus architecture simplifies interface design

Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous logic domains
• Data acquisition systems requiring precise timing control
• Network switch buffer memory applications

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements as original specifications may vary by production date. Check for moisture sensitivity handling instructions prior to assembly. Ensure replacement parts meet identical electrical and mechanical specifications for critical designs.

Selection Notes

Select this component when a 32K x 9 synchronous FIFO with 10 ns access time is required. Compare against the 72V271 series for similar performance in different packaging or temperature ranges. Consider the 72281 series if wider data bus widths are needed. Verify package compatibility with existing PCB footprints before finalizing the design.

Part Context

This part belongs to the Renesas 72V271 family of high-performance synchronous FIFOs. It shares architectural similarities with other members like the 72V271LA15TF but differs in specific package options and manufacturing revisions. The 72271LA15TFI represents an earlier iteration within this product line, now classified as obsolete.

Replacement Considerations

The 72V271LA15TFI is a direct functional substitute with identical electrical characteristics. Other compatible alternatives include the 72V271LA15TF8 for tape-and-reel packaging. Verify pinout compatibility and thermal performance when transitioning to these newer equivalents.
