72265LA15PFGI

Overview

The 72V265LA15PFGI is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation, belonging to the 72V series. It features a storage capacity of 288K bits, organized as 16K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates on a single 3V to 3.6V power supply with a maximum current consumption of 55mA. The device is housed in a 64-TQFP package (10x10mm) and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Supports First-Word-Fall-Through (FWFT) mode for rapid data availability
• Includes programmable flags for status monitoring
• Capable of signal retiming applications

Applications

• Data buffering in high-speed digital systems
• Signal retiming interfaces
• Protocol conversion between different clock domains

Procurement Notes

Verify part authenticity through authorized channels due to End-of-Life status. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3). Check for specific packaging suffixes if tape-and-reel versus tray delivery is required. Ensure design-in compatibility with existing PCB footprints for the 64-TQFP package.

Selection Notes

Select this component when a 16K x 18 word depth is required for synchronous buffering. Consider the 10ns access time and 66.7MHz speed for timing constraints. Evaluate the 3.3V operating voltage against system power rails. Compare pinout and package dimensions with alternative FIFOs if space or I/O requirements differ.

Part Context

This part belongs to the IDT/Renesas SuperSync FIFO family, known for low-power operation and high performance. The 72V265LA variant specifically offers 18-bit width, distinguishing it from 9-bit or 36-bit counterparts in the same series. It represents a transition from Integrated Device Technology (IDT) branding to Renesas Electronics following corporate acquisitions.

Replacement Considerations

Check for direct cross-reference part numbers such as IDT72V265LA15PFGI. Verify functional equivalence regarding pinout, voltage levels, and timing parameters before substitution.
