7203L15JGI8

Overview

The Renesas Electronics Corporation 7203L15JGI8 is an asynchronous FIFO memory integrated circuit with a storage capacity of 18 kbit, organized as 2K x 9. It features a maximum data rate of 40 MHz and an access time of 15 ns. The device operates on a single 5.0 V supply voltage within a range of 4.5 V to 5.5 V, drawing a maximum supply current of 120 mA. It utilizes a 32-pin PLCC package for surface mount installation.

Feature Summary

• Supports asynchronous read and write operations with simultaneous data handling capabilities
• Includes auto-retransmit functionality allowing reset of the read pointer to its initial position
• Provides status flags including Empty, Half-Full, and Full indicators to manage data flow

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between components operating at different speeds
• 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 during storage and assembly. Ensure replacement parts are functionally compatible with existing designs.

Selection Notes

Select this component for applications requiring reliable asynchronous FIFO buffering with specific 2K x 9 organization. Consider the 15 ns access time for timing constraints in your system design. Evaluate the 32-pin PLCC package compatibility with your PCB layout. Assess power consumption limits against available supply rails.

Part Context

This part belongs to the 7203 series of asynchronous FIFO memories from Renesas Electronics. It is designed for high-performance data buffering in digital systems. The series offers various access times and organizations to suit different application needs. This specific model provides a balance of speed and density for general-purpose buffering tasks.

Replacement Considerations

Check for functional equivalents with identical pinouts and specifications. Verify that substitute parts support the same 2K x 9 organization and 15 ns access time. Ensure compatibility with 5.0 V TTL interfaces and asynchronous operation modes.
