72V01L25JI

FIFOs Memory Overview

The Renesas 72V01L25JI is an asynchronous FIFO memory device featuring a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates with a maximum data rate of 28.5MHz and provides a typical access time of 25ns. The component supports unidirectional bus direction and includes relay capability for signal buffering. It functions within a supply voltage range of 3V to 3.6V, with a maximum supply current of 60mA. The device is housed in a 32-PLCC package and is rated for commercial operating temperatures from 0°C to 70°C.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible data buffering.
• Unidirectional bus architecture simplifies interface design for specific data flow requirements.
• Integrated relay capability enables signal buffering and isolation between system components.

FIFOs Memory Applications

• Data buffering in interprocessor communication systems
• Signal buffering in local area network interfaces
• Graphics data buffering applications

FIFOs Memory Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations exist within the 72V01 series. Confirm that the specific part number matches the required temperature grade and package type. Check for any product change notices or end-of-life announcements prior to procurement. Ensure compatibility with the target system's voltage levels and timing constraints.

FIFOs Memory Selection Notes

Select this component when a small-capacity asynchronous FIFO with unidirectional data flow is required. The 512x9 organization suits applications needing moderate buffering depth. Verify that the 25ns access time meets the system's throughput requirements. Consider the 32-PLCC package if surface-mount assembly with J-leads is preferred over other form factors.

FIFOs Memory Part Context

The 72V01L25JI belongs to the Renesas 72V01 family of asynchronous FIFOs. This series is designed for general-purpose data buffering tasks. The device shares architectural similarities with other members of the 72V family but differs in specific speed grades and organizational parameters. It represents a legacy solution for low-density memory buffering applications.

FIFOs Memory Replacement Considerations

The 72V01L15JG is listed as an upgrade alternative for the discontinued 72V01L25J variant. Verify pinout and electrical compatibility before substitution. Other family members may offer different speeds or capacities but require careful evaluation of functional differences.
