7204L15JI8

Overview

The Renesas Electronics Corporation 7204L15JI8 is an asynchronous First-In-First-Out (FIFO) memory device belonging to the 7204L series. It features a storage organization of 4K words by 9 bits, providing a total capacity of 36 kilobits. The component operates with a maximum access time of 15 nanoseconds and supports a data rate up to 22.22 MHz. It functions within a supply voltage range of 4.5 V to 5.5 V and utilizes a 32-pin PLCC package.

Feature Summary

• Asynchronous FIFO architecture for independent read and write clock domains
• Parallel CMOS interface supporting bidirectional data bus operation
• Integrated status flags indicating full, empty, and parity conditions

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging in high-speed digital communication systems
• Synchronization buffers in embedded control applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Review official discontinuance notices for lifecycle management. Ensure ESD protection protocols are followed during handling and storage to maintain device integrity.
