7201LA25J8

Overview

The Renesas 7201LA25J8 is an asynchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 28.5MHz and a typical access time of 25ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. The component is housed in a 32-PLCC package with dimensions of 14x11.46mm and is designed for surface mount installation. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface bridging.
• Unidirectional bus architecture simplifies control logic for single-direction data flow applications.
• Integrated status flags provide real-time empty and full indicators for buffer management.

Applications

• Data buffering between microprocessors and peripheral devices operating at different clock speeds
• Interface bridging in communication systems requiring temporary data storage
• Digital signal processing pipelines needing intermediate memory stages

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for available surplus stock from certified suppliers if new production is unavailable. Ensure packaging integrity matches specifications for surface mount assembly processes.

Selection Notes

Select this component when asynchronous FIFO functionality with 512x9 organization is required. Consider the 25ns access speed and 28.5MHz data rate for timing compatibility. Evaluate the 32-PLCC package suitability for existing PCB layouts. Verify power supply constraints align with the 4.5V to 5.5V operating range and 80mA current draw.
