72261LA15TFI8

Overview

The Renesas Electronics Corporation 72261LA15TFI8 is a synchronous FIFO memory device with a capacity of 144K bits, organized as 16K words by 9 bits. It operates on a single 4.5V to 5.5V power supply and features a maximum clock frequency of 66.7MHz with an access time of 10ns. The component utilizes a 64-TQFP package (10x10mm) and supports programmable flags for status monitoring.

Feature Summary

• Synchronous operation with clocked read and write controls
• Supports programmable flags for status indication
• Uni-directional data bus architecture

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

Verify the obsolete status and end-of-life notifications before procurement planning. Confirm RoHS compliance requirements against specific project standards. Check for moisture sensitivity levels and recommended reflow profiles during handling. Ensure availability of alternative sources or equivalent replacements due to discontinuation.

Selection Notes
