7203L15JGI

Overview

The Renesas Electronics Corporation 7203L15JGI is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K words by 9 bits. It features a uni-directional bus architecture and supports data rates up to 40MHz with a maximum access time of 15ns. The component operates on a single supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 120mA. It is housed in a 32-PLCC surface-mount package and is rated for industrial operating temperatures between -40°C and +85°C.

Feature Summary

• Supports asynchronous read and write operations with simultaneous data handling capabilities
• Includes auto-retransmit functionality to reset the read pointer upon low pulse activation
• Provides status flags indicating empty, half-full, and full conditions to prevent overflow or underflow

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate matching applications between disparate data streams
• Digital signal processing interfaces needing temporary data storage

Procurement Notes

Verify the specific suffix JGI against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for end-of-life notices or discontinuation announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a uni-directional asynchronous FIFO with 9-bit width is required. Ensure the system voltage aligns with the 4.5V to 5.5V range. Consider the 32-PLCC package constraints for PCB layout. Verify that the 15ns access time meets the timing requirements of the connected logic devices.

Part Context

This part belongs to the 7203 series of asynchronous FIFO memories. It shares functional compatibility with other members of the 720X family, allowing for potential design flexibility within similar product lines. The series is designed for applications demanding reliable first-in-first-out data handling without complex programming overhead.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic cross-references may not match the specific electrical characteristics or pinout configuration of the 7203L15JGI.
