7207L15J

Overview

The Renesas Electronics Corporation 7207L15J is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 288K bits, organized as 32K words by 9 bits. It operates with a maximum data rate of 40MHz and provides a typical access time of 15ns. The device functions within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 120mA. It utilizes a 32-pin PLCC package (14x11.46mm) designed for surface mount installation. The component supports unidirectional bus directionality and includes retransmit capability.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes retransmit capability allowing reset of the read pointer to its initial position
• Utilizes Full and Empty status flags to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between asynchronous clock domains
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity level handling precautions during storage and assembly. Validate pin compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when a 32K x 9 asynchronous FIFO with 15ns access time is required. Ensure system power supply remains within the 4.5V to 5.5V operating range. Consider the 32-PLCC package dimensions for board space constraints. Verify that unidirectional data flow meets application needs rather than bidirectional alternatives.

Part Context

This part belongs to the 7207 series of CMOS parallel FIFO memories manufactured by Renesas Electronics. It is functionally compatible with the broader 720X family of devices. The component represents a specialized memory solution designed for high-speed data transfer applications where asynchronous operation is critical.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete or discontinued. Evaluate alternative FIFO architectures from other manufacturers if direct replacement is necessary.
