72T3665L6-7BB

FIFOs Memory Overview

The Renesas 72T3665L6-7BB is an asynchronous and synchronous FIFO memory component with a capacity of 144K bits, organized as 4K words by 36 bits. It supports data rates of 66MHz and 150MHz with access times of 12ns and 3.8ns respectively. The device operates on a 2.5V supply voltage within the range of 2.375 V to 2.625 V. It is housed in a 208-PBGA (17x17) package and functions as a uni-directional buffer.

FIFOs Memory Feature Summary

• Supports both asynchronous and synchronous operation modes for flexible system integration
• Provides flexible Bus-Matching capabilities supporting x36, x18, and x9 data flow configurations
• Features clocked read and write controls for precise timing management

FIFOs Memory Applications

• High-speed data buffering in telecommunications systems
• Clock domain crossing interfaces in digital logic designs
• Data rate matching between peripheral devices and processors

FIFOs Memory Procurement Notes

This part number is officially listed as obsolete by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or approved replacement alternatives. Ensure compatibility with existing board layouts when sourcing substitutes due to the specific 208-PBGA package dimensions.

FIFOs Memory Selection Notes

Select this component only if legacy support for the 72T series TeraSync architecture is required. Verify that the 208-PBGA footprint matches the design constraints. Consider the obsolete status when planning long-term production cycles, as supply continuity cannot be guaranteed from original manufacturing sources.

FIFOs Memory Part Context

The 72T3665 belongs to the Renesas 72T TeraSync family of FIFO memories. These devices are designed for high-performance applications requiring reliable data storage and transfer between different clock domains. The family typically includes variants with varying depths and speeds, such as the 72T36105, which shares similar interface characteristics but offers greater depth.
