7204L20J

Overview

The Renesas Electronics Corporation 7204L20J is an asynchronous FIFO memory device belonging to the 7204 series. It features a storage capacity of 36 kbit organized as 4K x 9 bits. The component supports unidirectional data bus operation and includes relay capability for signal buffering. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power supply current of 120 mA. The device provides a typical access time of 20 ns and supports data rates up to 33.3 MHz. It is housed in a 32-PLCC package and is rated for industrial temperature ranges.

Feature Summary

• Asynchronous FIFO architecture enabling independent read and write clock domains
• Unidirectional data bus configuration for dedicated input or output paths
• Integrated relay capability to buffer and isolate signals between system segments

Applications

• Data buffering in high-speed digital communication interfaces
• Signal level translation and isolation between disparate logic families
• Temporary data storage in embedded processing systems requiring flow control

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure the selected package variant matches the target PCB footprint requirements. Validate RoHS compliance and moisture sensitivity levels prior to assembly integration.

Selection Notes

Select this component when designing systems requiring asynchronous data buffering with unidirectional flow. The 20 ns access time suits moderate-speed applications where precise timing alignment is not critical. Consider the 32-PLCC package constraints for board space. Evaluate the 120 mA current consumption against thermal management capabilities in the final enclosure design.

Part Context

The 7204L20J is part of the broader 7204 family of asynchronous FIFOs manufactured by Renesas Electronics. This series provides versatile memory solutions for bridging speed mismatches between different system components. The 7204L20J specifically targets applications needing reliable data storage with straightforward interface control signals.

Replacement Considerations

Consult official Renesas substitution guides for verified alternative part numbers. Cross-reference pinouts and electrical specifications carefully before replacing legacy components.
