72245LB10PF8

Overview

The Renesas Electronics Corporation 72245LB10PF8 is a synchronous FIFO memory device with a capacity of 4K x 18 bits. It operates at a data rate of 100MHz and features a 6.5ns access time. The component utilizes a TQFP-64 package and functions within a supply voltage range of 4.5V to 5.5V. It supports unidirectional bus operation and includes programmable flags for status monitoring.

Feature Summary

• Synchronous first-in, first-out memory architecture
• High-speed 100MHz data transfer capability
• Programmable flag support for status indication

Applications

• Data buffering in communication systems
• Interface bridging between different clock domains
• Temporary storage in high-speed digital circuits

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations may exist. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for obsolescence notices or product change notifications from the manufacturer to ensure long-term availability and specification stability.

Selection Notes

Select this component when a 4K x 18 synchronous FIFO is required with 100MHz performance. Ensure the design accommodates the 4.5V to 5.5V supply voltage range. Verify that the TQFP-64 package dimensions fit the PCB layout constraints and thermal requirements of the application environment.
