72205LB15PFI8

Overview

The Renesas 72205LB15PFI8 is a synchronous FIFO memory IC with a capacity of 4.5K bits (256 x 18). It operates at a data rate of 66.7MHz and features a 10ns access time. The device supports unidirectional bus direction and includes programmable flags. It functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 60mA. The component is housed in a 64-TQFP package and operates across a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation for reliable data buffering
• Programmable status flags for flow control
• Unidirectional data transfer architecture

Applications

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

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement alternatives. Ensure compliance with RoHS3 standards if applicable to the specific revision. Confirm package dimensions and pinout compatibility before integration into new designs.

Selection Notes

Select this part for applications requiring 256-word by 18-bit synchronous buffering. Verify that the 66.7MHz speed meets system timing requirements. Consider the 64-TQFP package constraints for PCB layout. Evaluate power consumption against the 60mA maximum limit. Check for end-of-life status implications on long-term production support.

Part Context

Part of the IDT 7200 series synchronous FIFO family. Manufactured by Renesas Electronics Corporation. Based on IDT legacy technology. Designed for general-purpose memory buffering tasks. Compatible with standard CMOS logic levels.

Replacement Considerations

Consult official Renesas documentation for direct cross-references. Verify electrical compatibility including voltage and speed. Check package pinout alignment. Review obsolescence notices for lifecycle management.
