72421L15PF8

FIFOs Memory Overview

The 72421L15PF8 is a synchronous First-In/First-Out (FIFO) memory integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 576 bits, organized as 64 words by 9 bits. The device supports a maximum data rate of 66.7MHz with an access time of 10ns. It operates on a single 5.0V power supply within a range of 4.5V to 5.5V and has a maximum supply current of 35mA. The component is housed in a 32-TQFP package measuring 7x7mm and functions within an industrial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Synchronous operation for reliable data buffering between systems with varying clock domains
• Uni-directional bus architecture simplifies interface design for specific data flow requirements
• Supports depth expansion to increase storage capacity beyond the base configuration

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Interface bridging between digital machines operating at different frequencies
• Controller applications requiring temporary data storage

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures during assembly. Validate package dimensions against PCB footprint specifications before integration into new designs.

FIFOs Memory Selection Notes

Select this component when synchronous FIFO functionality with 9-bit word width is required. Consider the 66.7MHz speed limit for high-frequency applications. Evaluate the 32-pin TQFP package constraints for board space. Compare against asynchronous alternatives if clock domain crossing flexibility is needed.

FIFOs Memory Part Context

This part belongs to the 7200 series of FIFO memories from Renesas. It shares architectural similarities with other members like the 72291L15PF8 but differs in organization and pin count. The series is known for low-power consumption and high drive capability. This specific model represents a smaller depth variant suitable for compact buffer applications.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify electrical parameters match original requirements. Consider obsolescence management strategies for existing products.
