7205L25JI

Overview

The Renesas Electronics Corporation 7205L25JI is an asynchronous FIFO memory device with a storage organization of 8K x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 25 ns. The component is housed in a PLCC-32 package and supports unidirectional data transfer.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes status flags such as Full, Empty, and Half-Full to manage buffer levels
• Features retransmit capability allowing the read pointer to reset to its initial position

Applications

• Multiprocessing systems requiring data buffering
• Rate matching applications between different speed domains
• Data acquisition systems needing temporary storage

Procurement Notes

Verify RoHS compliance status carefully as older variants may not meet current environmental standards. Confirm moisture sensitivity level requirements for surface mount assembly processes. Check for end-of-life notices or discontinuance announcements from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 5V logic interface is required for asynchronous FIFO applications. Ensure the system design accommodates the PLCC-32 package footprint. Verify that the 25 ns access time meets the timing constraints of the target application bus speeds.

Part Context

This part belongs to the 7205 series of asynchronous FIFO memories manufactured by Renesas Electronics. The series typically offers various access times and packaging options to suit different performance and board space requirements in industrial and commercial electronic designs.

Replacement Considerations

Check for functional equivalents within the same family such as the 7205L25J8 or IDT7205L25JI8. Verify pin compatibility and electrical specifications before substituting.
