72225LB25PFI8

Overview

The Renesas Electronics Corporation 72225LB25PFI8 is a synchronous FIFO memory device belonging to the 7200 series. It features an 18K storage capacity organized as 1K x 18 bits, supporting unidirectional data transfer at a maximum data rate of 40MHz with a 15ns access time. The component operates on a single 4.5V to 5.5V power supply and draws a maximum current of 60mA. It is housed in a 64-TQFP surface-mount package and supports programmable flags for status monitoring.

Feature Summary

• Synchronous operation with unidirectional bus direction
• Programmable flag support for status indication
• Surface mount installation type

Applications

• Data buffering between asynchronous systems
• Interface bridging in high-speed digital circuits
• Temporary data storage in communication protocols

Procurement Notes

Verify part authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the component may not meet current environmental standards. Check moisture sensitivity level handling procedures before assembly. Ensure replacement availability if long-term supply is required.

Selection Notes

Select this component for applications requiring moderate depth FIFO buffers with 18-bit word width. Consider the 40MHz speed limit and 15ns latency when designing timing-critical paths. Evaluate the 64-pin TQFP footprint against available PCB space. Compare against other 7200 series variants if different depths or speeds are needed.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs, which offers various configurations of memory depth and speed grades. The 72225 variant specifically provides 1K x 18 organization. Other members in the series include different capacities such as 512x18 or 2Kx18, catering to diverse buffering needs in embedded and industrial systems.
