72401L10P

FIFOs Memory Overview

The Renesas Electronics Corporation 72401L10P is an asynchronous First-In/First-Out (FIFO) memory device with a storage organization of 64 words by 4 bits. It operates on a single 5.0V supply and supports a maximum shift rate of 45MHz. The component utilizes RAM-based architecture to achieve low fall-through time and high data output drive capability. It is designed for applications requiring buffering between digital machines with widely varying operating frequencies.

FIFOs Memory Feature Summary

• Asynchronous read and write operations allow flexible interfacing between systems with different clock domains.
• Fully expandable by both bit width and word depth to accommodate custom memory configurations.
• Features low power consumption characteristics suitable for energy-efficient designs.

FIFOs Memory Applications

• High-speed communication system buffering
• Controller interface data management
• Digital machine frequency translation buffers

FIFOs Memory Procurement Notes

Verify the obsolete status and lead availability carefully, as this specific part number may no longer be in active production. Confirm package type compatibility and temperature grade requirements against current design specifications before procurement planning.

FIFOs Memory Selection Notes

Select this component when asynchronous FIFO functionality with 64x4 density is required. Ensure the design accommodates the 5.0V logic level and 45MHz speed limit. Consider alternative packages if surface-mount solutions are preferred over the through-hole DIP format.

FIFOs Memory Part Context

This device belongs to the IDT 72401 series of asynchronous FIFOs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 72403 but lacks the output enable pin found in that variant. The series is known for robust performance in industrial and commercial data handling applications.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers include 72401L10DB, 72401L10SO, and 72401L10SO8. Verify pinout and electrical specifications match before substitution.
