7203L15J

Overview

The Renesas Electronics Corporation 7203L15J is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K 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 40 MHz with a 15 ns access time. The component features unidirectional bus architecture and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Unidirectional data flow architecture for dedicated buffer applications
• Retransmit capability allowing pointer reset for data recovery

Applications

• Multiprocessing system data buffering
• Rate matching between asynchronous clock domains
• Data acquisition interface buffering

Procurement Notes

Verify the specific suffix J against official documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as sources indicate non-compliance. Check end-of-life notices for discontinuation impact on long-term availability.

Selection Notes

Select this component when a 2K x 9 depth is required with 15 ns speed at 5V logic levels. Ensure the design accommodates the 32-pin PLCC footprint and unidirectional data path constraints compared to bidirectional alternatives.

Part Context

Part of the 7203 series asynchronous FIFO family from Renesas. This series provides high-speed memory buffering solutions for digital signal processing and communication interfaces requiring reliable first-in-first-out data handling.

Replacement Considerations

IDT7203L15JI is a documented alias for this component. Verify pinout and electrical specifications match before substitution.
