72V243L6PF

FIFOs Memory Overview

The 72V243L6PF is a SuperSync II synchronous FIFO memory device manufactured by Renesas Electronics. It offers a total capacity of 36K bits, configurable as 2K words by 18 bits or 4K words by 9 bits. The component supports data rates up to 166MHz with an access time of 4ns. It operates on a 3.3V core voltage and features a uni-directional architecture. The device is housed in an 80-pin TQFP package with 80 lead counts.

FIFOs Memory Feature Summary

• Supports flexible bus-matching on both read and write ports for x9 and x18 configurations
• Includes programmable flags and full-water-full (FWFT) support capabilities
• Features variable clock cycle counting delay functionality

FIFOs Memory Applications

• High-speed data transfer systems requiring synchronous buffering
• Digital signal processing interfaces needing word-width flexibility
• Network equipment requiring reliable unidirectional data storage

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Check moisture sensitivity level (MSL 3) requirements for handling and storage conditions. Confirm package integrity for the 80-TQFP form factor. Ensure compatibility with 3.3V logic levels in target designs.

FIFOs Memory Selection Notes

Select this part when 36K-bit capacity and 166MHz speed are required. Choose the 2Kx18 or 4Kx9 configuration based on system bus width needs. Consider the TQFP-80 package for surface mount applications. Verify that uni-directional operation meets the specific data flow requirements of the design.

FIFOs Memory Part Context

This component belongs to the Renesas 72V SuperSync II family of synchronous FIFOs. It shares architectural similarities with other parts in the series but is distinguished by its specific 36K-bit capacity and 166MHz performance rating. The device represents a specialized solution for high-throughput memory buffering applications.

FIFOs Memory Replacement Considerations

The product status is listed as Obsolete. No public confirmed substitute part numbers are available in the provided documentation. Designers should evaluate alternative components from current production lines or consider redesigning for newer generation memory solutions.
