7205L50J

Overview

The Renesas Electronics Corporation 7205L50J is an asynchronous FIFO memory device with a storage capacity of 72K bits, organized as 8K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 50 ns. The component is housed in a 32-pin PLCC package and supports unidirectional data transfer at a data rate of up to 15 MHz.

Feature Summary

• Supports asynchronous and simultaneous read and write operations for multiprocessing applications
• Includes auto-retransmit capability allowing read pointer reset via low pulse
• Utilizes Full and Empty status flags to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring asynchronous data handling
• Rate buffer applications managing data flow speed differences
• Systems utilizing dual-port FIFO memory architectures

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity and moisture sensitivity levels prior to assembly to ensure reliability in final designs.

Selection Notes

Select this component for legacy systems requiring 8K x 9 word depth with 50 ns access speed. Ensure design compatibility with 5V logic levels and PLCC-32 footprint constraints. Consider functional equivalents if newer manufacturing processes or lead-free packaging are mandatory for the target application environment.

Part Context

This device belongs to the 7205 series of asynchronous FIFO memories manufactured by Renesas Electronics. It is functionally compatible with the broader 720X family, offering similar operational characteristics while providing specific timing and packaging configurations tailored for industrial and commercial electronic circuit implementations.

Replacement Considerations

Check for direct pin-compatible substitutes within the 7206 series or updated 7205 variants. Verify that alternative components maintain identical 8K x 9 organization and 50 ns access times to ensure seamless integration without schematic modifications.
