72V03L15J

FIFOs Memory Overview

The 72V03L15J is an asynchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 18K bits, organized as 2K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum supply current of 60mA. The device is housed in a 32-PLCC package (14x11.46 mm) and is designed for surface mount installation. It functions reliably across a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Unidirectional bus direction simplifies system design for specific data flow requirements.
• Repeater capability enables buffering and signal regeneration between different logic families or speeds.

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between components operating at different clock speeds
• Signal repeater applications in high-speed digital systems

FIFOs Memory Procurement Notes

Verify the exact ordering suffix and package variant when sourcing, as manufacturers may update part numbers or packaging formats over time. Confirm that the specified 32-PLCC package matches your PCB footprint requirements. Check for any recent Product Change Notices regarding material composition or assembly location changes to ensure compliance with your project specifications.

FIFOs Memory Selection Notes

Select this component when an asynchronous FIFO with 9-bit word width and 2K depth is required. Ensure the system voltage aligns with the 3 V to 3.6 V operating range. Consider the 40MHz speed limit and 15ns access time against your timing constraints. Verify that unidirectional data flow meets your application needs rather than bidirectional alternatives.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of asynchronous FIFO memories. The series offers various capacities and speeds, with the 72V03 model specifically providing 18K bit storage. These devices are commonly used in legacy and industrial systems requiring reliable data buffering without complex synchronization logic.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the same 72V series, such as variants with different speed grades or package options. Verify that any substitute maintains the 9-bit width and asynchronous functionality. Cross-reference with IDT equivalents if available, ensuring electrical parameters match exactly.
