• Bi-directional data transfer capability for flexible system integration
• High-speed operation supporting 66.7MHz clock rates with 10ns access time

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock domains
• Temporary data storage in telecommunications equipment

FIFOs Memory Procurement Notes

This component is classified as obsolete or discontinued by the manufacturer. Availability is limited to existing stock from authorized distributors or secondary market suppliers. Verify the specific revision level and manufacturing date code upon acquisition. Ensure compliance with RoHS directives if required for your application, as older batches may not meet current environmental standards. Confirm pin compatibility before integrating into new designs.

FIFOs Memory Selection Notes

Select this part when dual independent 18-bit wide synchronous FIFOs are required in a single package. The 144K total capacity suits applications needing moderate buffer sizes without consuming excessive board space. Consider the 3V to 3.6V supply requirement and ensure the system voltage aligns. The 128-TQFP package requires appropriate PCB footprint design. Evaluate alternative newer generation parts if long-term supply assurance is critical for production.

FIFOs Memory Part Context

The 72V845L15PF belongs to the Renesas 72V series of synchronous FIFOs. This series is designed for high-performance data buffering applications requiring fast access times and reliable data integrity. The device utilizes CMOS technology to achieve low power consumption while maintaining high-speed operation. It is part of a broader family of memory solutions offered by Renesas for industrial and communication markets.

FIFOs Memory Replacement Considerations

Direct replacements may be difficult due to the obsolete status. Check for updated Renesas 72V series variants with similar pinouts and specifications. Verify that any substitute maintains the 144K capacity and 18-bit width configuration. Ensure the replacement supports bi-directional data transfer and fits the 128-TQFP package.
