7208L20J

Overview

The Renesas Electronics Corporation 7208L20J is an asynchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 576K organized as 64K words by 9 bits. The component supports a data rate of 33.3MHz with a maximum access time of 20ns. It operates on a single-directional bus architecture and requires a supply voltage between 4.5V and 5.5V. The integrated circuit is housed in a 32-PLCC package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional bus architecture for data transfer
• Supports relay capability for signal buffering

Applications

• Data buffering in high-speed digital systems
• Interface bridging between components with different clock speeds
• Temporary data storage in communication protocols

Procurement Notes

Verify the exact suffix designation, as the provided model lacks the final character found in standard listings like J8. Confirm RoHS compliance status, as specific variants may not meet current environmental regulations. Check for End-of-Life (EOL) notifications from Renesas, as this series has faced discontinuation notices. Ensure the supplier provides valid traceability documentation for legacy components.

Selection Notes

Select this component when a 64K x 9 asynchronous FIFO is required. Compare against the 7207L20J8 for smaller capacities or the 7202LA20J8 for lower density options. Verify that the 32-PLCC package fits the target PCB footprint. Ensure the system design accommodates the 4.5V to 5.5V power supply range and 120mA maximum current consumption.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFOs, which also includes models like the 7203L20LB and 7208L20J8. These devices are designed for high-speed data handling applications. The series typically offers various densities and access times to suit different system requirements. Renesas continues to support these legacy parts through authorized distributors despite some EOL statuses.

Replacement Considerations

The IDT7208L20J8 is listed as an alias for this component. Verify pin compatibility and electrical specifications before substitution. Other members of the 7200 series may serve as alternatives if density differences are acceptable.
