72V245L15PF

FIFOs Memory Overview

The Renesas Electronics Corporation 72V245L15PF is a synchronous first-in, first-out (FIFO) memory device featuring an organization of 4K x 18 bits. It operates with a maximum clock frequency of 66.7 MHz and supports a data bus width of 18 bits. The component utilizes a unidirectional bus orientation and requires a supply voltage ranging from 3.0 V to 3.6 V. It offers a typical access time of 10 ns and functions within an industrial temperature range of -40°C to +85°C. The integrated circuit is housed in a 64-pin TQFP package.

FIFOs Memory Feature Summary

• Supports dual-clock operation with asynchronous read and write clocks or single-clock coincident timing for flexible system integration.
• Includes programmable almost-empty and almost-full flags with default settings, alongside standard empty and full status indicators.
• Features output enable control that places the output data bus into a high-impedance state when disabled.

FIFOs Memory Applications

• Optical disk controllers
• Local Area Networks (LANs)
• Interprocessor communication

FIFOs Memory Procurement Notes

Verify the specific suffix 'PFGI' against official documentation, as it may indicate lead-free compliance or industrial temperature grading compared to the base model. Confirm current availability status, as this series may be subject to end-of-life notices or limited production runs. Ensure compatibility with existing PCB footprints for the 64-pin TQFP package during procurement planning.

FIFOs Memory Selection Notes

Select this component for applications requiring 18-bit wide data buffering at speeds up to 66.7 MHz. It is suitable for systems needing independent read and write clock domains. Verify that the 3.3V logic levels match the interface requirements of the connected processors or network controllers. Consider the industrial temperature range if the deployment environment exceeds standard commercial limits.

FIFOs Memory Part Context

This part belongs to the 72V245 family of synchronous FIFOs, which serves as the 3.3V version of the legacy 72245 series. The family is designed for high-performance data buffering needs in networking and storage applications. It maintains functional compatibility with previous generations while offering improved power efficiency and expanded feature sets such as programmable flags.
