72401L35PDG

FIFOs Memory Overview

The Renesas Electronics Corporation 72401L35PDG is an asynchronous 64 x 4 First-In/First-Out (FIFO) memory device. It utilizes RAM-based architecture to provide low fall-through time and high data output drive capability. The component supports a maximum shift rate of 45MHz, making it suitable for high-speed communication and controller applications where buffering between digital machines of varying operating frequencies is required. It is fully expandable by both bit width and word depth.

FIFOs Memory Feature Summary

• Asynchronous read and write operations allow flexible buffering between systems with different clock speeds
• RAM-based design ensures low fall-through time for efficient data handling
• High data output drive capability supports robust signal transmission
• Fully expandable architecture allows customization of bit width and word depth

FIFOs Memory Applications

• High-speed communication systems requiring data buffering
• Controller applications managing data flow between varying frequency domains
• Digital machine interfaces needing asynchronous FIFO storage

FIFOs Memory Procurement Notes

Verify the exact suffix designation for the plastic DIP package variant, as official documentation lists the 72401L35P configuration. Confirm RoHS compliance status, noting that specific lead-free variants such as the L45SOG exist within the series while others may not meet current environmental standards. Ensure the obsolete status is accounted for in long-term supply planning.

FIFOs Memory Selection Notes

Select this component when asynchronous operation between disparate clock domains is necessary. The 45MHz speed rating suits high-frequency data transfer needs. Consider the 64 x 4 depth for moderate buffer requirements. Verify package availability, as the specific PDG suffix may require checking against the standard PDIP or SOIC listings for equivalent performance characteristics.

FIFOs Memory Part Context

The 72401 belongs to the 7200 series of asynchronous FIFOs from Renesas. This series is designed for general-purpose buffering in digital systems. The 72401 specifically offers a 64-word by 4-bit configuration. It is part of a broader family that includes variations in speed grades and package types, all sharing the core asynchronous RAM-based functionality.
