72241L15J

Overview

The 72241L15J is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 36K organized as 4K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 35mA. The device is housed in a 32-PLCC package and is designed for surface mount installation.

Feature Summary

• Synchronous operation with clocked read and write controls for precise data buffering
• Unidirectional bus architecture supporting 9-bit data width expansion
• Programmable flag support for status monitoring during operations

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the specific suffix J indicates the 32-PLCC package configuration. Confirm RoHS compliance status as documentation may indicate non-compliance. Check for discontinuation notices or end-of-life status before procurement planning. Ensure compatibility with 4.5V to 5.5V power supplies. Validate moisture sensitivity level requirements for assembly processes.

Selection Notes

Select this component when synchronous timing is required for 9-bit wide data paths. Consider the 4K depth for moderate buffering needs. Verify that the 10ns access time meets system latency requirements. Ensure the operating temperature range of 0°C to 70°C fits the application environment. Compare against other 72241 variants if different speeds or packages are needed.

Part Context

The 72241 series belongs to Renesas' SyncFIFO family, designed for high-speed data buffering applications. These devices utilize CMOS technology to provide reliable performance in digital systems. The 72241L15J specifically offers a balance of speed and density suitable for standard logic interfaces. It is part of a broader lineup including asynchronous and bidirectional options.

Replacement Considerations

Check for direct substitutes within the 72241 series with compatible pinouts. Verify electrical parameters such as voltage and speed match exactly. Consider package availability if 32-PLCC is restricted. Review manufacturer notices for recommended upgrades or obsolescence management.
