72261LA20TF

Overview

The 72261LA20TF is a 16K x 18 asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It operates with a supply voltage range of 4.5V to 5.5V and features a maximum access time of 20ns. The device is housed in a 64-pin TQFP package and supports parallel interface communication. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C. This component serves as a high-speed buffer for data storage and retrieval in complex electronic systems requiring reliable asynchronous memory performance.

Feature Summary

• Asynchronous operation with independent read and write control signals
• High-speed data access capabilities suitable for buffering applications
• Industrial temperature rating for robust environmental performance
• Wide supply voltage tolerance for flexible power integration

Applications

• Data buffering in telecommunications equipment
• Video signal processing and frame buffering
• Network router and switch memory interfaces
• Industrial control system data logging

Procurement Notes

Verify the specific suffix 'TF' against the manufacturer's official datasheet to confirm package type and moisture sensitivity level. Ensure the design accommodates the 4.5V to 5.5V operating range. Check for RoHS compliance status as older variants may differ from current standards. Confirm availability through authorized distributors given potential lifecycle changes.

Selection Notes

Select this component when asynchronous SRAM with 16K x 18 organization is required. Compare access times against system clock requirements to ensure 20ns latency is acceptable. Consider pin compatibility with existing 722xx family designs if upgrading from older versions. Evaluate power consumption differences between 3.3V and 5V families for thermal management.

Part Context

This part belongs to the 72261 series of SuperSync FIFOs and SRAMs. It shares functional similarities with other members of the 722xx family but differs in specific speed grades and packaging options. The 72261LA20 variant specifically targets applications needing moderate speed with wide data bus width.

Replacement Considerations

Check for direct pin-compatible upgrades within the 72V261 series for lower voltage operation. Verify if faster access time variants like the 72261LA15 are needed for higher throughput. Cross-reference with IDT equivalents if sourcing from alternative suppliers.
