72245LB15PF

Overview

The Renesas Electronics Corporation 72245LB15PF is a synchronous first-in, first-out (FIFO) memory device with an organization of 4K x 18. It features a bidirectional data bus and operates within a supply voltage range of 4.5 V to 5.5 V. The component provides a maximum access time of 10 ns and supports data rates up to 66.7 MHz. It is housed in a 64-pin TQFP package suitable for surface mount installation. The device functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Synchronous FIFO architecture supporting bidirectional data transfer
• Configurable programmable flags including almost-empty and almost-full indicators
• Supports both single-clock and dual-asynchronous clock operations
• Output enable control places the data bus in a high-impedance state

Applications

• Data buffering in optical disk controllers
• Local Area Network (LAN) interface buffering
• Interprocessor communication systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements as indicated by specific suffixes. Validate moisture sensitivity level handling procedures during assembly. Ensure pin compatibility with existing PCB footprints before integration into new designs.

Selection Notes

Select this component for applications requiring reliable synchronous data buffering with bidirectional capabilities. Consider the 10 ns access time for high-speed processing needs. Evaluate the 4K x 18 depth against system buffer requirements. Verify that the 5V logic levels match the target system's I/O standards.

Part Context

This part belongs to the Renesas 72245 series of synchronous FIFO memories. It serves as a specialized memory solution for temporary data storage between asynchronous or synchronous domains. The series is designed for high-performance data buffering tasks in industrial and commercial electronic systems.

Replacement Considerations

Consult official Renesas documentation for verified substitute part numbers. Cross-reference specifications such as access time, organization, and package type when evaluating alternatives.
