7201LA50P

Overview

The Renesas 7201LA50P is an asynchronous FIFO memory IC with a capacity of 512 x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 28.5 MHz. The device features a 50 ns access time and draws a maximum supply current of 80 mA. It is housed in a 28-pin DIP package (0.600 inch width) and is designed for surface mount or through-hole integration depending on the specific variant configuration.

Feature Summary

• Asynchronous operation allows independent read and write clock domains
• CMOS technology ensures low power consumption
• Relay capability supports signal buffering applications

Applications

• Data buffering between different speed logic circuits
• Interface bridging for parallel data transfer systems
• Signal processing pipeline staging

Procurement Notes

Verify component authenticity due to obsolete status. Confirm package type matches design requirements. Check RoHS compliance as some variants may not meet current standards. Validate datasheet revisions for electrical parameter consistency before integration into final designs.

Selection Notes

Select this part for applications requiring simple asynchronous buffering without complex control logic. Ensure system timing accommodates the 50 ns access delay. Verify that the 28-pin DIP footprint aligns with existing PCB layouts. Consider alternative packages if space constraints require smaller form factors.
