72225LB15J

Overview

The Renesas 72225LB15J is a synchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 18K bits, organized as 1K words by 18 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 and draws a maximum supply current of 60mA. The device is housed in a 64-pin TQFP package (10x10mm) and functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with clocked read and write controls for precise data buffering
• Programmable status flags indicating full and empty conditions
• Unidirectional bus architecture supporting high-speed data transfer
• Industrial-grade temperature rating for robust environmental performance

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling
• High-speed serial-to-parallel conversion tasks

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as original specifications may not meet current regulations. Validate package dimensions against PCB footprint designs. Check moisture sensitivity levels for proper storage and reflow soldering procedures. Ensure supply chain stability given discontinued manufacturing status.

Selection Notes

Select this component when 18-bit wide synchronous FIFO buffering is required. Consider the 10ns access time for timing-critical applications. Evaluate the 64-TQFP package compatibility with existing assembly processes. Compare power consumption against system thermal constraints. Verify interface compatibility with source and destination logic families.

Part Context

The 72225LB15J is part of Renesas' 7200 series of synchronous FIFO memories. This family offers various densities and speeds for different buffering needs. The 72225 variant specifically targets applications requiring 18-bit word width. It complements other members like the 72223 and 72224 series. The series is designed for reliable data flow management in digital systems.

Replacement Considerations

Check for direct pin-compatible substitutes from Renesas or IDT. Verify electrical parameters match original specifications. Consider alternative packages if lead availability is limited. Review updated datasheets for any functional changes in newer revisions.
