72V3690L6PF8

FIFOs Memory Overview

The Renesas Electronics Corporation 72V3690L6BB8 is a Super Sync II synchronous FIFO memory device. It features a storage capacity of 144K bits, organized as 4K words by 36 bits. The component supports unidirectional data transfer with a maximum clock frequency of 166 MHz and an access time of 4 ns. It operates within a supply voltage range of 3.15 V to 3.45 V and has a maximum supply current of 40 mA. The device is housed in a 144-pin PBGA package.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) functionality for immediate data availability upon read enable assertion.
• Includes programmable full and empty flags to indicate buffer status during operation.
• Features relay capability to allow cascading of multiple devices for expanded memory depth.

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Signal processing systems requiring precise timing alignment
• Network interface cards managing packet flow

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability should focus on the secondary market or authorized distributors holding remaining stock. Designers must confirm the specific suffix BB8 corresponds to the PBGA-144 package variant. Cross-reference with official discontinuation notices to ensure compliance with long-term supply requirements.

FIFOs Memory Selection Notes

Select this part only if the 36-bit data width and 4K depth match the system architecture exactly. Verify that the PBGA-144 package is compatible with the PCB footprint. Consider the 166 MHz speed requirement against the application's throughput needs. Ensure the design accounts for the unidirectional data flow constraint inherent to this specific model.

FIFOs Memory Part Context

The 72V3690 series belongs to Renesas' Super Sync II family of high-performance synchronous FIFOs. These devices are designed for applications requiring large data buffers with low latency. The 72V3690L6BB8 specifically utilizes the PBGA-144 package, distinguishing it from TQFP variants like the 72V3690L6PF which share similar electrical characteristics but differ in physical form factor.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers for this specific component were not identified in the provided documentation. Engineers should consult Renesas technical support for qualified alternatives or evaluate pin-compatible options from other manufacturers with matching 36-bit width specifications.
