72245LB15PFI

Overview

The Renesas Electronics Corporation 72245LB15PFI is a synchronous first-in, first-out (FIFO) memory device with an organization of 4K x 18. It features a 9-bit data bus width and supports bidirectional data transfer. The component has a maximum access time of 10 ns and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a TQFP-64 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 clocked read and write controls
• Bidirectional data bus interface for flexible system integration
• Programmable flag support for status monitoring

Applications

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

Procurement Notes

Verify the current lifecycle status as the component is listed as discontinued or end-of-life by major distributors. Confirm availability through authorized channels or secondary markets. Check for moisture sensitivity level compliance during handling. Ensure RoHS non-compliance aligns with project requirements. Validate pinout compatibility before procurement.

Selection Notes

Select this component for applications requiring synchronous data buffering with 18-bit word widths. Consider the 10 ns access speed for high-frequency data transfers. Evaluate the TQFP-64 package constraints for PCB layout. Compare against the 72V245 series if 3.3V operation is required instead of the 5V range specified here.

Part Context

This part belongs to the Renesas 72245 series of synchronous FIFO memories. It is functionally equivalent to earlier IDT72245 designs. The device provides reliable data storage for buffering streams between asynchronous or synchronous domains. It is designed for industrial and commercial environments within the specified temperature limits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The 72V245 series is noted as a functional variant but operates at 3.3V, which differs from the 5V requirement of this part. Verify electrical compatibility before considering alternatives.
