72V235L15PFI

FIFOs Memory Overview

The Renesas Electronics Corporation 72V235L15PFI is a synchronous first-in, first-out (FIFO) memory device with a storage capacity of 36K bits, organized as 2K words by 18 bits. It operates on a single 3.3V power supply within the 3V to 3.6V range and supports a maximum data rate of 66.7MHz. The component features a 10ns access time and is housed in a 64-pin TQFP package. It includes programmable flags for status monitoring and supports First-Word-Fall-Through (FWFT) functionality.

FIFOs Memory Feature Summary

• Supports unidirectional data transfer with dedicated read and write clock inputs for independent operation.
• Includes programmable flags that allow users to define custom threshold levels for full and empty conditions.
• Provides First-Word-Fall-Through capability to reduce latency when reading the first word from the FIFO.

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Clock domain crossing interfaces between asynchronous logic blocks
• Temporary storage in telecommunications equipment

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Availability is restricted to existing stock or secondary market sources. Verify RoHS compliance status carefully, as older production runs may not meet current environmental standards. Confirm package integrity and moisture sensitivity level handling requirements before installation.

FIFOs Memory Selection Notes

Engineers should evaluate alternative components due to the discontinuation status of this part. Consider devices with similar 18-bit width and synchronous timing characteristics. Ensure replacement options support the required 3.3V operating voltage and offer comparable access times. Check for updated packaging options and long-term supply agreements if continuing production.

FIFOs Memory Part Context

The 72V235L15PFI belongs to the 72V series of synchronous FIFOs designed for high-performance memory applications. It serves as a bridge between different speed domains in complex electronic systems. The device was widely used in industrial and communication infrastructure where reliable data buffering was critical.
