72215LB15PFI

Overview

The Renesas Electronics Corporation 72215LB15PFI is a synchronous FIFO memory device with a storage capacity of 9K bits, organized as 512 words by 18 bits. It operates at a maximum clock frequency of 40 MHz and features a 25 ns access time. The component supports unidirectional data transfer and includes programmable flags for status monitoring. It functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 60 mA. The device is housed in a 68-pin PLCC package and is rated for an industrial operating temperature range of 0°C to +70°C.

Feature Summary

• Synchronous operation with programmable full and empty flags for precise buffer management
• Unidirectional data bus architecture supporting 18-bit wide data transfers
• CMOS technology ensuring low power consumption during active and standby states

Applications

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

Procurement Notes

Verify the specific package variant and revision level against the manufacturer's latest documentation before procurement. Confirm that the required operating temperature range aligns with the commercial specification (0°C to +70°C) rather than the extended industrial range if higher thermal tolerance is needed. Check for end-of-life status or obsolescence notices from Renesas Electronics to ensure long-term availability for production cycles.

Selection Notes

Select this component when a moderate-depth, wide-data FIFO is required for synchronous applications. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage requirements. Consider the 68-pin PLCC package constraints for PCB layout. Verify that the 40 MHz maximum clock speed meets the system timing requirements. Evaluate alternative packages if surface-mount TQFP options are preferred over leaded PLCC.

Part Context

The 72215LB15PFI belongs to the Renesas 72215 series of synchronous FIFO memories. This series is designed for high-performance data buffering applications requiring reliable first-in-first-out data handling. The device utilizes CMOS technology to provide efficient operation with low power dissipation. It is part of a broader family of memory solutions offered by Renesas for industrial and commercial electronic systems.

Replacement Considerations

Consult Renesas official documentation for direct pin-compatible replacements or updated series members. Verify electrical specifications and package dimensions for any substitute components to ensure compatibility with existing board layouts.
