72265LA10PFI

Overview

The Renesas Electronics Corporation 72265LA10PFI is a SuperSync FIFO memory device with an organization of 16K x 18 bits. It operates on a 3.3V supply voltage, ranging from 3.0V to 3.6V. The component features a 10ns read/write cycle time and a 6.5ns access time, supporting data rates up to 100MHz. It utilizes independent read and write clocks for simultaneous operations and includes programmable flags for status monitoring. The device is housed in a 64-pin TQFP package.

Feature Summary

• SuperSync architecture enabling independent read and write clock domains for simultaneous data handling
• Fixed low first word data latency time ensuring rapid initial data availability
• Programmable Almost-Empty and Almost-Full flags for precise buffer management
• Auto power down functionality designed to minimize standby power consumption

Applications

• Networking equipment requiring large data buffering
• Video processing systems needing high-speed data transfer
• Telecommunications infrastructure utilizing synchronous interfaces
• Data communications applications demanding low latency

Procurement Notes

Verify the exact suffix against official Renesas documentation, as variations like PFG or PFI may indicate specific temperature grades or packaging types. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the design supports the required 3.3V logic levels and check for any pin-compatible alternatives within the 72V2x5 family if supply constraints exist.

Selection Notes

Select this component when a 16K x 18 depth and width configuration is required for synchronous data buffering. It is suitable for designs needing independent clock domains and fixed low latency. Consider the 64-pin TQFP package constraints and verify that the 3.3V operating voltage aligns with the system's power rails. Evaluate the need for auto power down features for energy efficiency requirements.

Part Context

This part belongs to the Renesas 72V265 SuperSync FIFO series, which offers functionally compatible versions to the older 5V 722x5 family. The LA variant specifically denotes 3.3V operation, replacing the Frequency Select pin found in earlier models. This simplifies design by removing the need to manually select between RCLK and WCLK frequencies.

Replacement Considerations

The IDT72V265LA10PFG is listed as an alias for this component. Other parts in the 72V2x5 family may be pin-compatible but differ in voltage or speed specifications. Verify functional compatibility before substituting with other SuperSync FIFO variants.
