72225LB25TFI8

Overview

The Renesas 72225LB25TFI8 is a synchronous FIFO memory device with a capacity of 18K bits, organized as 1K words by 18 bits. It operates at a maximum data rate of 40MHz with an access time of 15ns. The component supports unidirectional data transfer and functions within a supply voltage range of 4.5V to 5.5V. It features programmable status flags for full and empty conditions. The device is housed in a 64-lead TQFP package measuring 10x10mm and is rated for industrial operating temperatures from 0°C to 70°C.

Feature Summary

• Synchronous single-clock operation for reliable data buffering
• Programmable Full and Empty status flags for flow control
• Expandable depth and width architecture
• Surface-mount packaging for automated assembly

Applications

• Data buffering between asynchronous systems
• Rate matching in communication interfaces
• Interprocessor communication links
• Digital signal processing pipelines

Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm package type and temperature grade alignment. Confirm RoHS compliance status as legacy 7200 series parts may vary. Check current production status as many variants are discontinued. Ensure moisture sensitivity level handling procedures are followed during storage and assembly.

Selection Notes

Select this part when a 1K x 18 synchronous buffer is required. Compare access times and clock speeds against system timing requirements. Verify that the 64-TQFP footprint matches the PCB layout. Consider alternative suffixes if different temperature ranges or packaging formats are needed for the specific application environment.

Part Context

This component belongs to the Renesas 7200 series of high-speed FIFO memories. The series includes various densities and speed grades. The 72225 variant specifically provides 18-bit wide data paths. These devices are designed for high-performance digital applications requiring efficient data storage and retrieval without complex addressing logic.

Replacement Considerations

Check for direct pin-compatible replacements within the 72225 family. Verify functional equivalence for speed and organization. Note that some distributors list IDT equivalents which may share specifications.
