7202LA15JI

Overview

The Renesas Electronics Corporation 7202LA15JI is an asynchronous FIFO memory device belonging to the 7202L series. It features a storage organization of 1K x 9 bits, providing a total capacity of 9 kilobits. The component supports CMOS parallel interface operation with a specified access time of 15 nanoseconds. Designed for unidirectional data flow, it operates within a standard voltage range and utilizes a PLCC-32 package. This integrated circuit is suitable for applications requiring rate buffering or protocol conversion in multiprocessing systems.

Feature Summary

• Supports asynchronous read and write operations allowing simultaneous data transfer
• Includes status flags such as Full and Empty to manage buffer overflow and underflow conditions
• Features auto-retransmit capability to reset the read pointer upon command
• Compatible with TTL logic levels for straightforward system integration

Applications

• Multiprocessing systems requiring data synchronization between different clock domains
• Rate buffering applications where input and output data rates differ
• Protocol conversion interfaces between disparate communication standards
• Digital signal processing pipelines needing temporary data storage

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing system voltage requirements and interface standards before procurement. Check for moisture sensitivity handling instructions if the component has been stored for extended periods. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when a 1K x 9 asynchronous FIFO with 15ns access time is required. Consider the PLCC-32 package constraints regarding PCB layout and thermal management. Evaluate whether the unidirectional bus architecture meets the specific data flow direction needs of the design. Compare performance metrics against alternative devices in the 7202L family if higher density or speed is necessary.
