7208L20J8

Overview

The 7208L20J8 is an asynchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 576K bits, organized as 64K words by 9 bits. The device supports unidirectional bus architecture with a data rate of 33.3MHz and an access time of 20ns. It operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 120mA. The component is housed in a 32-PLCC package and is designed for surface mount installation.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes auto-retransmit capability to reset the read pointer
• Provides status flags including Empty, Half-Full, and Full indicators

Applications

• Multiprocessing systems requiring data buffering
• Rate buffer applications between mismatched speed components
• Asynchronous data transfer interfaces

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Check moisture sensitivity level handling procedures during assembly. Validate package integrity against the 32-PLCC specification before integration into design.

Selection Notes

Select this component for designs requiring 64K x 9 word depth asynchronous buffering. Ensure power supply stability within the 4.5V to 5.5V range for proper operation. Consider the 32-PLCC package dimensions for PCB layout constraints. Verify thermal performance under maximum current consumption conditions.

Part Context

This part belongs to the 7200 series of high-speed asynchronous FIFO memories. It offers expandability in both word depth and bit width. The device is functionally compatible with other members of the 720X family, allowing for design flexibility across similar memory architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available. The component is listed as obsolete or discontinued. Designers should evaluate pin-compatible alternatives from the same manufacturer family or assess redesign requirements for new projects.
