72V03L25JI

FIFOs Memory Overview

The Renesas 72V03L25JI is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 18K bits, organized as 2K words by 9 bits. It operates with a maximum data rate of 28.5MHz and an access time of 25ns. The device supports unidirectional bus direction and includes relay capability. It functions within a supply voltage range of 3V to 3.6V, with a maximum supply current of 60mA. The component is designed for surface mount installation in a 32-PLCC package and supports an industrial operating temperature range from -40°C to 85°C.

FIFOs Memory 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.
• Relay capability enables signal re-driving for improved signal integrity across traces.

FIFOs Memory Applications

• Data buffering between asynchronous logic blocks
• Interface bridging between different clock domains
• Temporary data storage in high-speed digital systems

FIFOs Memory Procurement Notes

Verify the exact suffix designation during procurement, as variations such as JGI or JI may indicate differences in packaging, RoHS compliance, or temperature grade. Confirm current availability status, as some variants in this series are marked as obsolete or end-of-life. Ensure the selected part matches the required operating temperature range and voltage specifications for the target application environment.

FIFOs Memory Selection Notes

Select this component when a unidirectional asynchronous FIFO with 2Kx9 organization is required. Compare against other 72V series parts if bidirectional support or different word widths are needed. Verify that the 32-PLCC package fits the PCB layout constraints. Consider the 25ns access time and 28.5MHz speed against system timing requirements to ensure adequate performance margins.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of asynchronous FIFOs, which provides various memory depths and data widths. The 72V03 variant specifically offers 18K-bit capacity. Other members in the family include devices with different organizations like 4Kx9 or 8Kx9, and varying pin counts or features. This series is designed for general-purpose buffering in embedded and industrial applications.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the IDT/Renesas portfolio, such as the IDT72V03L25JGI, noting potential differences in packaging or environmental compliance. Verify pin-to-pin compatibility before substitution. Consult official obsolescence notices for legacy variants like the 7203L25JI to ensure long-term supply chain stability.
