72V3640L15PFI8

FIFOs Memory Overview

The 72V3640L15PFI8 is a synchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 36K bits, organized as 1K words by 36 bits. The device supports unidirectional data transfer with a maximum clock frequency of 66.7MHz and an access time of 10ns. It operates on a single 3.3V power supply within the range of 3.15V to 3.45V, drawing a maximum supply current of 40mA. The component is housed in a 128-pin TQFP package measuring 14x20mm and is rated for industrial operating temperatures from -40°C to +85°C.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) timing mode for reduced latency
• Includes programmable Almost-Full and Almost-Empty status flags
• Features relay capability for bypassing FIFO logic via mailbox registers

FIFOs Memory Applications

• High-speed data buffering between asynchronous system domains
• Interface bridging in telecommunications equipment
• Data acquisition systems requiring precise synchronization

FIFOs Memory Procurement Notes

This component has reached End-of-Life (EOL) status and is officially discontinued by the manufacturer. Procurement must rely exclusively on remaining surplus stock or authorized secondary market distributors. Verify RoHS compliance status carefully, as this specific part number is identified as non-compliant. Confirm package authenticity and check for moisture sensitivity level degradation due to age before integration into new designs.

FIFOs Memory Selection Notes

Select this component only if legacy compatibility with the IDT 72V3640 series is required. The 128-TQFP package necessitates specific PCB footprint planning. Ensure design margins accommodate the 3.3V nominal voltage range. Consider that the EOL status limits long-term supply availability, making this suitable primarily for maintenance repairs rather than new product development.

FIFOs Memory Part Context

The 72V3640L15PFI8 belongs to the Renesas 72V SuperSync family of high-performance synchronous FIFOs. This series is designed for applications demanding fast data throughput and flexible interface control. The 'L15' suffix indicates the 10ns speed grade, while 'PFI8' denotes the 128-pin TQFP package with tape-and-reel shipping configuration.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, direct pin-to-pin replacements may require verification against updated datasheets from alternative manufacturers.
