7207L35J8

Overview

The Renesas Electronics Corporation 7207L35J8 is an asynchronous FIFO memory integrated circuit manufactured in a 32-pin PLCC package. It provides a storage capacity of 288K bits, organized as 32K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 22.22MHz and an access time of 35ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 120mA. The component is designed for surface mount installation and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes auto-retransmit capability to reset the read pointer upon pulse
• Utilizes status flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring data buffering
• Rate buffer applications between mismatched speed interfaces
• Asynchronous data transfer control logic

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as the part does not meet current standards. Check moisture sensitivity level handling procedures during assembly. Ensure replacement parts match pinout and electrical specifications for direct integration into existing designs without modification.

Selection Notes

Select this component when a 32K x 9 word depth is required for asynchronous buffering. The 35ns access time suits moderate-speed parallel interface applications. Verify that the 32-PLCC package fits the target PCB layout constraints. Consider the unidirectional bus directionality against system architecture needs before finalizing the design choice.

Part Context

This part belongs to the 7200 series of high-speed FIFO memories originally developed by Integrated Device Technology (IDT) and later acquired by Renesas. The 7207 model specifically denotes the 32K x 9 organization variant. It shares functional compatibility with other members of the 720X family, allowing for scalable memory expansion in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Renesas discontinuation notices for recommended alternatives or verify cross-compatibility with similar IDT/Renesas FIFO families.
