72401L45PDG

FIFOs Memory Overview

The Renesas 72401L45PDG is an asynchronous 64 x 4 First-In/First-Out (FIFO) memory device. It features a low fall-through time and supports a maximum shift rate of 45MHz, making it suitable for high-speed communication and controller applications. The component operates at a core voltage of 5.0V and offers high data output drive capability. It is fully expandable by both bit width and word depth to accommodate varying system requirements.

FIFOs Memory Feature Summary

• Asynchronous read and write operations allow buffering between digital machines with widely varying operating frequencies
• Low fall-through time ensures efficient data transfer performance
• High data output drive capability supports robust signal integrity in demanding environments

FIFOs Memory Applications

• High-speed communication systems
• Controller applications requiring data buffering
• Interfaces between digital machines with differing clock speeds

FIFOs Memory Procurement Notes

Verify the specific suffix 'PDG' against official Renesas documentation to confirm package type and lead-free status, as standard listings often cite PDIP or SOIC variants. Confirm current availability status, as many 72401 variants are marked obsolete. Ensure compatibility with 5.0V logic levels and check for industrial temperature range options if required for the application environment.

FIFOs Memory Selection Notes

Select this component when an asynchronous FIFO with 64-word depth and 4-bit width is required. Consider the 45MHz speed limit and 5.0V operation. Evaluate expandability needs for bit width and word depth. Compare against synchronous alternatives if clock alignment is feasible. Verify package constraints and thermal requirements for the target design.

FIFOs Memory Part Context

The 72401 belongs to Renesas' AsyncFIFO family, designed for bridging data transfers between systems operating at different speeds. This series emphasizes low latency and high drive strength. The L45 variant specifically denotes the 45MHz speed grade within the product line, distinguishing it from slower models like the L10 or L15.
