72251L15PFG

Overview

The Renesas Electronics Corporation 72251L15PFG is a synchronous FIFO memory device with a capacity of 72K bits, organized as 8K words by 9 bits. It operates at a maximum data rate of 66.7MHz with an access time of 10ns. The component supports unidirectional bus direction and programmable flags. It functions within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 50mA. The device is designed for surface mount installation in a 32-PLCC package (14x11.46mm) and supports an industrial operating temperature range from -40°C to 85°C.

Feature Summary

• Synchronous operation with high-speed data transfer capabilities up to 66.7MHz
• Programmable status flags for monitoring read/write operations
• Unidirectional data flow architecture for buffer applications
• Industrial temperature range support for robust environmental performance

Applications

• High-speed data buffering between asynchronous system domains
• Interface bridging in telecommunications equipment
• Data acquisition systems requiring precise timing control
• Network processing units managing packet flows

Procurement Notes

Verify the exact suffix PFG against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote specific packaging or reliability grades. Confirm RoHS compliance status, as some variants may differ. Check for obsolescence notices or PCNs affecting availability. Ensure the supplier provides traceability certificates if required for your application standards.

Selection Notes

Select this component when a synchronous interface is required for 9-bit wide data paths with moderate depth. Compare against the 72251L15JGI variant if a lower voltage supply or different temperature range is needed. Consider the 72V series if low power consumption is critical. Verify that the 32-PLCC package fits the PCB footprint constraints and that the 10ns access time meets the system clock requirements.

Part Context

This part belongs to the IDT 7200 series of FIFO memories, widely used for data buffering and protocol conversion. The 72251 model specifically offers 72Kbit capacity. Renesas acquired IDT's logic products, continuing the lineage of these high-performance memory devices. This series is known for its flexibility in configuring word lengths and depths through external pins.

Replacement Considerations

Check for direct replacements like the 72251L15JGI, noting differences in voltage and temperature ratings. Verify pin-to-pin compatibility before substitution. Consult Renesas for updated equivalents if the PFG suffix indicates a discontinued lot.
