7203L25J8

Overview

The Renesas 7203L25J8 is an asynchronous FIFO memory IC with a capacity of 18K bits (2K x 9). It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum data rate of 28.5 MHz. The device has a typical access time of 25 ns and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous dual-port architecture for independent read and write clock domains
• Hardware Full and Empty flags to prevent buffer overflow and underflow conditions
• Uni-directional bus configuration optimized for specific data flow paths

Applications

• High-speed data buffering between disparate system components
• Clock domain crossing interfaces in digital logic circuits
• Data storage in communication protocol bridges

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. Validate package integrity upon receipt, as moisture sensitivity requires proper handling procedures during assembly.

Selection Notes

Select this component when asynchronous operation with 25 ns access time is required. Ensure the design supports 5 V logic levels and utilizes the 32-PLCC form factor. Consider bidirectional alternatives if signal directionality needs reversal.

Part Context

Part of the 7203 series of high-performance FIFO memories from Renesas. Designed for applications requiring reliable data buffering without complex control logic overhead.

Replacement Considerations

IDT7203L25J8 is a documented alias for this component. Verify pin compatibility and electrical specifications before substitution.
