7207L20LB

Overview

The Renesas Electronics Corporation 7207L20LB is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 288K bits, organized as 32K words by 9 bits. It operates with a maximum data rate of 40MHz and an access time of 20ns. The device supports unidirectional bus direction and functions within a supply voltage range of 4.5V to 5.5V. It is housed in a 32-PLCC package with dimensions of 14x11.46mm and supports surface mount installation.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit capability allowing reset of the read pointer to its initial position
• Status flags including Empty, Half-Full, and Full to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications for mismatched data transfer speeds
• Parallel interface data storage and retrieval

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level (MSL 3) handling procedures during assembly. Validate pin compatibility with existing PCB layouts before integration into new designs.

Selection Notes

Select this component for applications requiring 32K x 9 word depth with 20ns access speed. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the 32-PLCC package constraints for board space. Evaluate thermal performance within the -40°C to +85°C industrial temperature range for reliability.

Part Context

Part of the 7200 series asynchronous FIFO family from Renesas Electronics. Designed for high-performance data buffering in parallel interfaces. Shares functional compatibility with other members of the 720X family while offering specific timing characteristics suited for industrial and commercial applications.

Replacement Considerations

Consult manufacturer documentation for verified substitute part numbers. Cross-reference specifications such as access time, organization, and package type when evaluating alternatives.
