72265LA20TF

Overview

The Renesas 72265LA20TF is a 16K x 18 SuperSync FIFO memory device operating at a 3.3V supply voltage. It features a synchronous interface with independent read and write clocks, supporting data rates up to 100MHz. The component utilizes a 64-pin TQFP package and offers low first word data latency. It includes programmable flags for status monitoring and supports auto power down modes to minimize standby consumption.

Feature Summary

• SuperSync architecture with independent read and write clock domains
• Low first word data latency with fixed timing characteristics
• Programmable Almost-Empty and Almost-Full flag support
• Auto power down functionality for reduced standby current

Applications

• Networking equipment buffering
• Video signal processing systems
• Telecommunications data interfaces
• High-speed data communications

Procurement Notes

Verify the specific suffix 'L' and '20' against official datasheets to confirm pinout and speed grade compatibility. Confirm RoHS compliance status as legacy parts may vary. Check for moisture sensitivity level requirements during storage and handling. Validate that the 64-TQFP package dimensions match the target PCB footprint exactly before procurement.

Selection Notes

Select this component when a 16K x 18 depth and width configuration is required for synchronous buffering. Ensure the system design accommodates independent clock domains for read and write operations. Verify that the 3.3V logic levels are compatible with the surrounding circuitry. Consider the 64-pin TQFP package constraints for board space and thermal management requirements in the final design.

Part Context

This part belongs to the 72V2x5/722x5 SuperSync FIFO family, designed for high-performance data buffering. It serves as a 3.3V version of the older 5V 722x5 series, offering functional compatibility while reducing power consumption. The removal of the Frequency Select pin simplifies clocking configurations compared to previous generations.

Replacement Considerations

IDT72265LA20TF is a verified substitute part number.
