72271LA15TF

Overview

The Renesas Electronics Corporation 72271LA15TF is a synchronous FIFO memory device belonging to the SuperSync family. It provides a storage capacity of 32K words by 9 bits, totaling 288K bits. The component operates with a maximum data rate of 66.7MHz and features an access time of 10ns. It supports unidirectional bus direction and includes programmable flags for status indication. The device is designed for surface mount installation in a 64-TQFP package.

Feature Summary

• Supports independent read and write clocks allowing simultaneous operations
• Features fixed, low first word data latency time
• Includes auto power down functionality to minimize standby power consumption
• Offers retransmit operation capability

Applications

• Data buffering between asynchronous systems
• Clock domain crossing applications
• High-speed data acquisition systems

Procurement Notes

Verify current availability as this component may be discontinued or subject to limited supply conditions. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement. Ensure compatibility with existing PCB footprint and soldering profiles. Check for alternative packaging options if standard tray quantities are unavailable.

Selection Notes

Select this component when a 32K x 9 synchronous FIFO with 10ns access time is required. Consider the 64-TQFP package constraint and 3V to 3.6V operating voltage range. Evaluate the need for independent clock domains and specific flag configurations such as almost-empty or almost-full indicators.

Part Context

This part belongs to the IDT/Renesas SuperSync FIFO series, known for high-performance memory buffering. It serves as a successor or variant to earlier models like the 72V271, maintaining pin compatibility while offering optimized latency characteristics. The 72271LA15TF represents a specific configuration within the broader 722x1 product line.

Replacement Considerations

Consider the 72V271LA15TF as a potential substitute due to similar specifications and pin compatibility. Verify functional equivalence regarding latency and clock independence. Other variants in the 722x1 series may offer different capacities or packages.
