7200L25JI8

Overview

The Renesas Electronics Corporation 7200L25JI8 is an asynchronous FIFO memory integrated circuit. It features a storage organization of 256 words by 9 bits, providing a total capacity of 2 kilobits. The device operates with a maximum access time of 25 nanoseconds and supports unidirectional data transfer. It is housed in a 32-pin PLCC package.

Feature Summary

• Asynchronous read and write operations allow simultaneous independent control of input and output pointers.
• Built-in status flags indicate full, half-full, and empty conditions to manage data flow.
• Auto-retransmit capability enables resetting the read pointer to its initial position.

Applications

• Multiprocessing systems requiring data buffering between processors.
• Rate matching applications where data sources and sinks operate at different speeds.
• Digital signal processing interfaces needing temporary data storage.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check for moisture sensitivity labels and adhere to recommended reflow profiles during assembly to prevent damage.

Selection Notes

Select this component when a small-capacity, high-speed asynchronous buffer is required. Ensure system voltage requirements match the specified operating range. Verify that the 32-pin PLCC footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the 7200 series of CMOS parallel FIFO memories. It shares functional compatibility with other members of the family, differing primarily in depth and speed grades. The series is designed for robust performance in industrial and commercial environments.

Replacement Considerations

Consult official datasheets for cross-reference candidates within the same product family. Verify pinout compatibility and electrical specifications before substitution. Contact the manufacturer for current availability and approved alternative part numbers.
