72205LB25PFI

Overview

The Renesas 72205LB25PFI is a synchronous FIFO memory integrated circuit belonging to the 7200 series. It provides a storage capacity of 18K bits, organized as 1K words by 18 bits. The device supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates on a single power supply ranging from 4.5V to 5.5V, with a maximum supply current of 60mA. The component is housed in a 64-TQFP package measuring 14x14mm and is rated for industrial operating temperatures between -40°C and +85°C.

Feature Summary

• Synchronous operation ensures data integrity through clock-synchronized read and write cycles.
• Unidirectional bus architecture simplifies interface design for specific data flow requirements.
• Programmable status flags allow for precise monitoring of buffer full and empty conditions.

Applications

• Rate matching between asynchronous data sources and processing units
• Data buffering in high-speed digital signal processing systems
• Interface bridging in multiprocessing environments

Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity handling during storage and assembly. Validate package dimensions against PCB footprint specifications. Ensure replacement availability aligns with long-term production needs.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO is required. Verify that the 40MHz speed meets system timing constraints. Consider the 64-pin TQFP package for surface mount compatibility. Evaluate power consumption limits against available thermal management solutions. Confirm that unidirectional data flow matches the application architecture.

Part Context

This part belongs to the Renesas 7200 series of high-performance FIFO memories. The series offers various configurations differing in depth, width, and speed grades. The 72225 variant shares similar electrical characteristics but differs in memory organization. These components are designed for robust performance in industrial and commercial applications requiring reliable data buffering.
