7201LA20JI8

Overview

The Renesas 7201LA20JI8 is an asynchronous FIFO memory integrated circuit belonging to the 7200 series. It provides a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The device supports a maximum data rate of 33.3MHz with a 20ns access time. It operates on a single power supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 80mA. The component utilizes a 32-pin PLCC package with J-leads for surface mount installation.

Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Supports bidirectional data flow through relay capability
• Provides status flags for full and empty conditions

Applications

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

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations exist within the 7201L family. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Check for discontinuation notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a 512x9 asynchronous FIFO is required with 20ns performance. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Verify that the 32-PLCC package fits the board layout constraints and that no programmable flag features are needed.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFOs. It shares architectural similarities with other members like the 7201LA20J8 but differs in package type and potentially manufacturing lot specifications. The series is designed for general-purpose memory buffering applications requiring simple interface control.

Replacement Considerations

IDT7201LA20J8 is listed as an alias for this component. Verify pinout compatibility and electrical parameters before substitution. Other 7201L variants with different access times or packages require careful evaluation.
