72V3680L7-5PF

FIFOs Memory Overview

The Renesas Electronics 72V3680L7-5PF is a synchronous FIFO memory device belonging to the 72V series. It features a storage capacity of 576K bits, organized as 16K words by 36 bits. The component supports unidirectional data transfer with a maximum data rate of 133.3MHz and an access time of 5ns. It operates within a supply voltage range of 3.15V to 3.45V and draws a maximum supply current of 40mA. The device is housed in a 128-LQFP package (128-TQFP) and functions within an industrial temperature range of 0°C to 70°C.

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Availability is restricted to existing stock or surplus channels. Verify RoHS compliance status, as indicated documentation may show non-compliance. Confirm moisture sensitivity level handling requirements prior to assembly. Evaluate replacement options from authorized distributors due to end-of-life status.

FIFOs Memory Selection Notes

Select this part only if legacy compatibility with the 72V3680 family is required. Ensure design constraints accommodate the 128-pin TQFP footprint and 3.3V logic levels. Consider that the 5ns access speed suits high-frequency applications up to 133.3MHz. Verify that the unidirectional bus direction meets system architecture needs without requiring bidirectional variants.

FIFOs Memory Part Context

The 72V3680L7-5PF is part of the Super Sync II family of synchronous FIFOs designed for high-performance digital signal processing and networking applications. It utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed operation. The device integrates control logic for easy interface with microprocessors and DSPs.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers include SN74V3680-15PEU and SN74V3680-6PEU from Texas Instruments. These alternatives offer similar specifications but require verification of pinout compatibility and electrical characteristics before integration.
