7202LA50LB

Overview

The Renesas Electronics Corporation 7202LA50LB is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates with a maximum data rate of 15MHz and has a typical access time of 50ns. The device supports unidirectional bus direction and includes relay capability. It functions 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-CLCC package measuring 11.43x13.97mm and is designed for surface mount installation.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Relay capability enables the transfer of data between different clock domains without loss.
• Unidirectional bus architecture simplifies system design for specific data flow requirements.

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock frequencies
• Temporary data storage in communication protocol converters

Procurement Notes

Verify the exact suffix LB against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as historical records indicate non-compliance for some variants in this series. Check for obsolescence notices or production change notifications that may affect long-term availability or sourcing channels.

Selection Notes

Select this component when a 1K x 9 word depth is required for asynchronous buffering. Ensure the system design accommodates the 32-CLCC package footprint and the 4.5V to 5.5V power supply constraints. Compare performance metrics such as access time and data rate against alternative FIFOs if higher throughput is needed.
