72205LB25J

Overview

The Renesas Electronics Corporation 72205LB25J is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 4.5K bits, organized as 256 words by 18 bits. The component supports unidirectional data transfer with a maximum clock frequency of 40MHz and an access time of 15ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 60mA. The device is housed in a 68-PLCC package.

Feature Summary

• Synchronous operation with dedicated read and write clocks for precise data buffering
• Programmable status flags indicating full, empty, and half-full conditions
• Unidirectional bus architecture simplifying interface design
• CMOS technology ensuring low power consumption

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous logic components
• Temporary storage in telecommunications equipment
• Data acquisition system front-end buffering

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt, as PLCC packages are sensitive to mechanical stress during handling and installation.

Selection Notes

Select this component when a 256x18 synchronous FIFO is required with 15ns access speed. Ensure the application supports 5V logic levels and unidirectional data flow. Consider pin compatibility if replacing older IDT variants. Verify thermal management needs within the specified operating temperature range.

Part Context

Part of the 7200 series synchronous FIFO family, designed for reliable data buffering in industrial and commercial applications. The 72205 variant specifically offers 18-bit width, distinguishing it from narrower 8-bit or 9-bit counterparts in the same series.

Replacement Considerations

IDT72205LB25J is a direct equivalent part number. Cross-reference with other 72205 series variants for package differences.
