72225LB15PF

Overview

The Renesas Electronics Corporation 72225LB15PF is a synchronous first-in, first-out (FIFO) memory device with a storage capacity of 18K bits, organized as 1K words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 66.7 MHz with a 10 ns access time. The component features unidirectional bus directionality and is housed in a 64-TQFP package measuring 14x14 mm. It includes programmable flag support but lacks full-word-first-full capability or relay capabilities.

Feature Summary

• Synchronous FIFO architecture for reliable data buffering
• Programmable status flags for system monitoring
• Unidirectional data transfer interface

Applications

• Data buffering in high-speed digital systems
• Interprocessor communication interfaces
• Network packet buffering applications

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Buyers must confirm the authenticity of legacy stock and check for potential obsolescence notices or last-time buy information before procurement decisions are finalized.

Selection Notes

Engineers requiring replacement components should consider the 72225LB10PFG as an official upgrade alternative provided by Renesas. Selection criteria should prioritize compatibility with existing 64-TQFP footprints and ensure that the target application can accommodate the specific electrical characteristics of the 7200 series family. Verify that the required speed and depth specifications align with the available substitute options.

Part Context

The 72225LB15PF belongs to the Renesas 7200 series of synchronous FIFO memories, which are designed for high-performance data buffering tasks. This series typically offers various density and speed combinations to suit different system requirements. The part represents a legacy product line from IDT, now integrated into Renesas' portfolio, commonly used in telecommunications and industrial control environments where deterministic latency is critical.

Replacement Considerations

The 72225LB10PFG is listed as an official upgrade replacement by Renesas Electronics Corporation.
