7201LA15JGI8

Overview

The Renesas Electronics Corporation 7201LA15JGI8 is an asynchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns with a data rate of 40 MHz. The component utilizes a unidirectional bus architecture and is housed in a 32-PLCC package. It supports relay capability but does not include programmable flags or First Word Fall Through (FWFT) support.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• Integrated relay capability for signal buffering

Applications

• Data buffering between asynchronous logic blocks
• Clock domain crossing interfaces
• High-speed serial-to-parallel conversion systems

Procurement Notes

Verify the specific suffix JGI8 against official datasheets to confirm package type and compliance status. Confirm moisture sensitivity level requirements for surface mount assembly processes. Check current lifecycle status as previous variants may be obsolete. Ensure ordering quantities align with manufacturer standard packaging specifications.

Selection Notes

Select this component when a 512x9 word depth is required for unidirectional data transfer. Verify that the 15 ns access time meets system timing constraints. Ensure the design accommodates the 32-pin PLCC footprint and 4.5 V to 5.5 V power supply requirements without additional level shifting.

Part Context

This part belongs to the 7201L series of high-performance CMOS FIFOs from Renesas. It serves as a specialized memory solution for temporary data storage in digital systems requiring precise synchronization between different operational speeds.

Replacement Considerations

The 7201LA15JI8 is listed as a direct substitute, though it may have different lifecycle status.
