7207L25JI8

Overview

The Renesas Electronics Corporation 7207L25JI8 is an asynchronous FIFO memory device with a storage capacity of 288K bits, organized as 32K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 22.22 MHz. The component features a 35 ns access time and draws a maximum supply current of 120 mA. It utilizes a 32-pin PLCC package with J-leads (14x11.46 mm) for surface mount installation.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Uni-directional bus architecture for dedicated data flow control
• Retransmit capability allowing reset of the read pointer to its initial position

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between asynchronous clock domains
• Data acquisition systems needing overflow prevention

Procurement Notes

Verify RoHS compliance status as the component may not meet current environmental regulations. Confirm availability through authorized distributors as stock levels are limited. Check for moisture sensitivity handling requirements during storage and assembly. Validate pin compatibility if replacing existing designs in production.

Selection Notes

Select this part for applications requiring high-density asynchronous buffering with a 9-bit word width. Ensure the design accommodates the 32-PLCC package dimensions and thermal characteristics. Verify that the 4.5V to 5.5V supply range aligns with the system power architecture. Consider the 35ns access speed against system timing constraints.

Part Context

This component belongs to the 7207 series of CMOS parallel FIFO memories. It is functionally compatible with the broader 720X family, offering similar pinouts and operational logic. The device is designed for robust performance in industrial environments, providing reliable data integrity for critical memory buffer applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-reference options based on identical specifications: 32K x 9 organization, 35ns access time, 32-PLCC package, and 5V operation. Verify functional equivalence before implementation.
