72V243L7-5PF

FIFOs Memory Overview

The Renesas Electronics 72V243L7-5PF is a synchronous FIFO memory device belonging to the 72V2x3 series. It features a data organization of 4K x 18 bits, providing a total capacity of 72 kilobits. The component operates with a maximum clock frequency of 66.7 MHz and supports a read/write cycle time of 10 nanoseconds. It utilizes a 3.3V power supply voltage range, typically between 3.15V and 3.45V. The integrated circuit is housed in a 64-pin TQFP package.

FIFOs Memory Feature Summary

• Supports dual-clock operation allowing asynchronous or coincident read and write clocks for flexible data buffering applications.
• Provides programmable almost-empty and almost-full flags with default settings to manage buffer levels effectively.
• Features output enable functionality 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 current availability status as this specific part number may be subject to discontinuation or limited stock conditions. Confirm RoHS compliance requirements against project specifications, noting that older variants may not meet current environmental standards. Ensure the 64-pin TQFP package dimensions align with existing PCB footprints before finalizing procurement decisions.

FIFOs Memory Selection Notes

Select this component for designs requiring 18-bit wide data paths and synchronous buffering capabilities. Consider the 10ns access speed for systems operating up to 66.7MHz. Evaluate the 3.3V logic level compatibility with the rest of the system. Verify if the available flag outputs meet the specific flow control requirements of the target application architecture.

FIFOs Memory Part Context

This device is part of the Renesas 72V2x3 family of synchronous FIFO memories. The family includes variations such as the 72V245, which shares similar architectural characteristics but differs in pinout or specific feature sets. These components are designed for high-speed data buffering in digital signal processing and communication interfaces.

FIFOs Memory Replacement Considerations

Check for direct cross-references within the 72V2x3 series, such as the 72V245, ensuring pin compatibility and functional equivalence. Verify if newer revisions from Renesas offer improved environmental compliance while maintaining electrical performance parameters.
