7207L50J

Overview

The Renesas Electronics Corporation 7207L50J is a CMOS parallel FIFO memory device with a storage organization of 32K x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features an access time of 50 ns. The component is housed in a 32-pin PLCC package and supports asynchronous read and write operations. This specific part number is designated as obsolete by the manufacturer.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes Full and Empty status flags to prevent data overflow and underflow
• Features auto-retransmit capability allowing reset of the read pointer

Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition systems needing temporary storage
• Digital signal processing interfaces

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Procurement is restricted to existing surplus stock from third-party distributors. Verify RoHS compliance status, as older batches may not meet current environmental standards. Confirm moisture sensitivity level handling requirements before installation. Availability is limited and subject to lot verification.

Selection Notes

Engineers should evaluate modern high-speed SRAM or advanced FIFO alternatives due to the obsolescence of this legacy component. Consider interface compatibility and pin configuration when migrating designs. Ensure new selections support required operating temperatures and voltage levels. Review datasheets for updated performance metrics and availability timelines to maintain long-term supply chain stability.

Part Context

The 7207 series represents a family of dual-port FIFO memories designed for high-speed data buffering. The 7207L50J specifically offers a 50 ns access time variant within this lineup. It is functionally compatible with earlier generations but provides optimized performance for synchronous and asynchronous data transfer needs in industrial and commercial electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers must identify equivalent components based on functional specifications such as 32K x 9 organization, 50 ns access time, and PLCC-32 packaging. Cross-reference with current Renesas product portfolios for modern replacements.
