72261LA15TFI

Overview

The 72261LA15TFI is a SuperSync FIFO memory component manufactured by Renesas Electronics. It features a storage organization of 16K x 9 bits, providing a total capacity of 144 Kbits. The device operates with a maximum data rate of 66.7 MHz and supports a read/write cycle time of 10 ns. It utilizes a 3.3 V supply voltage and is housed in a 64-pin TQFP package.

Feature Summary

• SuperSync architecture enabling independent read and write clocks for simultaneous operations
• Fixed low first word data latency time for retransmit operations
• Programmable Almost-Empty and Almost-Full flags for status signaling
• Auto power down capability to minimize standby power consumption

Applications

• Networking equipment buffering
• Video signal processing
• Telecommunications systems
• Data communications interfaces

Procurement Notes

Verify the exact suffix configuration as the provided model number may differ from standard catalog listings. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or obsolescence warnings associated with this specific part variant before finalizing orders.

Selection Notes

Select this component for applications requiring high-speed synchronous data buffering with fixed latency characteristics. Ensure the system design accommodates the 3.3 V logic levels and the 64-pin TQFP footprint. Verify that the required depth and width expansion capabilities align with the project's memory architecture requirements.

Part Context

This part belongs to the 72V261 series of SuperSync FIFOs. It serves as a functionally compatible version of the older 5 Volt 72261 family but operates at 3.3 V for lower power consumption. The series is designed for applications needing large data buffering capabilities with predictable timing performance.
