72245LB10PFI

Overview

The Renesas Electronics Corporation 72245LB10PFI is a high-speed synchronous FIFO memory device belonging to the 7200 series. It features a memory organization of 4K x 18 bits, providing a total capacity of 72 kilobits. The component supports a maximum data rate of 100MHz with a fast access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and includes programmable flag support for status monitoring. The device is housed in a 64-LQFP surface-mount package.

Feature Summary

• High-speed synchronous data buffering with low latency
• Programmable full and empty flags for precise flow control
• Bidirectional data bus interface for flexible system integration

Applications

• High-speed data acquisition systems requiring temporary storage
• Buffering between asynchronous clock domains in digital logic
• Interface bridging in telecommunications equipment

Procurement Notes

Verify current availability as this component may be subject to discontinuation notices from the manufacturer. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the specific suffix matches required packaging and pinout configurations for your design.

Selection Notes

Select this part when a 4K x 18 word depth is required with sub-10ns access times. Consider the 64-LQFP package constraints for PCB layout. Evaluate power consumption specifications against system thermal limits during continuous operation at maximum clock frequencies.

Part Context

This component is part of the Renesas 7200 series of synchronous FIFOs, designed for high-performance memory applications. It succeeds earlier generations by offering improved speed and integrated status flags. The 72245 variant specifically targets wide-data-path applications compared to narrower 8-bit or 9-bit options in the same family.

Replacement Considerations

Check for direct pin-compatible substitutes within the 72245 series, such as variants with different access times or packages. Verify that any replacement maintains the 4K x 18 organization and 5V operating voltage requirements.
