72251L15PFG8

Overview

The Renesas Electronics Corporation 72251L15PFG8 is a synchronous First-In, First-Out (FIFO) memory device. It features a storage capacity of 72K bits organized as 8K words by 9 bits. The component supports a maximum data rate of 66.7 MHz with an access time of 10 ns. It operates on a single 5.0 V power supply within a voltage range of 4.5 V to 5.5 V. The device utilizes a unidirectional bus architecture and is housed in a 32-pin TQFP package.

Feature Summary

• Synchronous FIFO architecture for efficient data buffering
• Unidirectional data transfer capability
• High-speed operation supporting up to 66.7 MHz clock rates

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm package type and reel specifications. Confirm current production status as some variants in this series are discontinued. Ensure compatibility with existing PCB footprints for the 32-pin TQFP form factor before procurement.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 9-bit width is required. Compare against other 72251 series variants if different access times or pin counts are needed. Verify that the 10 ns access time meets system timing requirements for the target application speed.

Part Context

This part belongs to the Renesas 72251 series of synchronous FIFOs. These devices are designed for high-performance data buffering applications requiring reliable synchronization between asynchronous domains. The series offers various configurations to suit different memory depth and interface needs.

Replacement Considerations

Check for direct cross-reference part numbers from IDT or Renesas with identical pinouts and electrical characteristics. Verify availability of alternative packages if surface-mount constraints differ.
