72261LA15TFGI

Overview

The Renesas 72261LA15TFGI is a synchronous FIFO memory IC with a capacity of 144K bits, organized as 16K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 66.7 MHz. The device features a 10 ns access time and is housed in a 64-LQFP package. It includes programmable flags for status monitoring and supports depth and width expansion.

Feature Summary

• Synchronous operation with clocked read and write controls
• Programmable full and empty flags for buffer management
• Supports parallel bus expansion for increased data width or depth

Applications

• High-speed data buffering between asynchronous systems
• Data acquisition system interfaces
• Telecommunications equipment signal processing

Procurement Notes

Verify current availability as the component may be subject to obsolescence notices. Confirm package type matches design requirements. Check for RoHS compliance status. Validate pinout compatibility if replacing existing designs. Consult manufacturer documentation for end-of-life timelines.

Selection Notes

Select this part for applications requiring reliable synchronous data storage with wide bus capabilities. Ensure supply voltage matches the 4.5 V to 5.5 V requirement. Consider the 64-LQFP package constraints for PCB layout. Verify that the 10 ns access time meets system timing specifications.

Part Context

This component belongs to the SuperSync family of synchronous FIFOs from Renesas. It provides high-performance data buffering solutions for digital systems. The series is known for its flexibility in expanding memory depth and width through external connections.

Replacement Considerations

Check for direct substitutes with identical pinouts and electrical characteristics. Verify that alternative parts support the same 16K x 9 organization and 66.7 MHz data rate. Ensure compatible packaging and operating temperature ranges.
