7207L15JI

Overview

The Renesas Electronics Corporation 7207L15JI 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 an access time of 15ns. The device supports unidirectional bus direction and includes retransmit capability. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 120mA. The component is housed in a 32-PLCC package (14x11.46mm) and is rated for an industrial operating temperature range from -40°C to +85°C.

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate package dimensions and pinout compatibility during integration planning. Review manufacturer product change notices for any historical modifications affecting form or function before finalizing procurement decisions.

Selection Notes

Select this component when a 32K x 9 asynchronous FIFO with 15ns access time is required. Ensure system power supplies remain stable within the 4.5V to 5.5V range. Verify that the 32-PLCC surface mount package fits the PCB layout constraints. Consider the industrial temperature rating if the application environment exceeds standard commercial limits. Check for functional equivalents if new production volume is needed.

Part Context

This part belongs to the 7200 series of asynchronous FIFO memories manufactured by Renesas Electronics. It shares architectural similarities with other members like the 7207L15JG but differs in package type and specific suffix designations. The series is designed for high-speed data transfer applications where independent read and write clocks are necessary.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Evaluate alternative FIFO architectures or newer generation components from the manufacturer for long-term supply stability.
