72215LB25J8

Overview

The Renesas Electronics Corporation 72215LB25J8 is a synchronous FIFO memory device featuring a storage organization of 512 words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 40 MHz with an access time of 25 ns. The component utilizes a unidirectional bus configuration and is housed in a 68-PLCC package. It functions within an operating temperature range of 0°C to +70°C and draws a maximum supply current of 60 mA.

Feature Summary

• Synchronous operation for precise data buffering between asynchronous system domains
• Unidirectional data flow architecture simplifying interface design
• High-speed performance supporting up to 40 MHz clock frequencies

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between microprocessors and peripheral devices
• Temporary storage in communication protocol conversion circuits

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the series. Confirm RoHS compliance status, as indicated sources show non-compliance. Check for End-of-Life notices or obsolescence warnings before finalizing procurement plans due to potential availability constraints.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 18-bit width is required. Ensure the system operates within the specified 4.5 V to 5.5 V voltage range. Verify that the 68-PLCC package fits the PCB layout constraints. Consider thermal management requirements given the 0°C to +70°C operating range.

Part Context

This part belongs to the Renesas 72215 series of synchronous FIFOs. It is designed for applications requiring reliable data buffering with predictable timing. The 18-bit width makes it suitable for parallel data paths common in industrial and telecommunications equipment.

Replacement Considerations

Check for direct pin-to-pin replacements within the same Renesas family. Verify compatibility with existing board layouts and software drivers if substituting.
