7205L20J8

Overview

The Renesas 7205L20J8 is an asynchronous FIFO memory device with a storage capacity of 72K bits, organized as 8K words by 9 bits. It features a unidirectional bus direction and supports relay capability. The component operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 120 mA. Key performance metrics include a data rate of 33.3 MHz and an access time of 20 ns. It is housed in a 32-PLCC package (14x11.46 mm) designed for surface mount installation. The device functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Unidirectional data flow simplifies system design for specific buffer applications.
• Hardware Full and Empty flags provide status monitoring to prevent data overflow or underflow conditions.

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital communication systems
• Temporary data storage in embedded processing architectures

Procurement Notes

Verify the obsolete status and end-of-life notices before procurement planning. Confirm RoHS compliance requirements against project specifications, as this part may not meet current environmental standards. Validate pin compatibility and electrical parameters against target designs. Source from authorized distributors or secondary markets due to limited availability. Review datasheet revisions for any functional updates or handling instructions.

Selection Notes

Select this component when a fixed 8K x 9 depth is required for unidirectional buffering. Ensure the system supports asynchronous clocking schemes compatible with the 20 ns access time. Verify that the 32-PLCC package fits the PCB layout constraints. Consider power consumption limits within the 120 mA maximum rating. Evaluate if the lack of programmable flags meets the specific status monitoring needs of the application.

Part Context

This device belongs to the Renesas 7200 series of asynchronous FIFO memories. It shares architectural similarities with other parts in the family, such as the 7205L50P and 7205L25J8, differing primarily in speed grade and package type. The series is designed for general-purpose memory buffering tasks in industrial and commercial electronics.

Replacement Considerations

Direct substitutes include the IDT7205L20J8. Other compatible options within the same family are the 7205L25J8 and 7205L50P, though these differ in access speed and package configuration. Verify pinout and electrical characteristics before substitution.
