72V3650L15PFI

FIFOs Memory Overview

The 72V3650L15PFI is a synchronous first-in, first-out (FIFO) memory device manufactured by Renesas Electronics. It features a storage organization of 256K x 9 or 128K x 1 bits, providing substantial buffering capacity for high-speed data applications. The component operates within a supply voltage range of 3.15 V to 3.45 V and utilizes a TQFP-128 package. Designed for industrial environments, it supports an operating temperature range from -40°C to +85°C. This specific variant is identified as an end-of-life product.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture supporting bidirectional data flow between independent clock domains
• Configurable data bus width allowing selection between 9-bit or 1-bit modes
• Programmable status flags indicating buffer full and empty conditions
• Industrial-grade thermal stability for reliable operation in demanding environments

FIFOs Memory Applications

• High-speed data buffering in telecommunications infrastructure
• Interface bridging between microprocessors and peripheral devices with asynchronous clocks
• Data acquisition systems requiring temporary storage before processing
• Network equipment packet buffering and traffic management

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the authenticity of existing inventory due to the end-of-life status. Replacement planning is strongly recommended as sourcing new units directly from the manufacturer is impossible. Ensure any acquired units meet original specifications for compatibility.

FIFOs Memory Selection Notes

Engineers selecting this part should consider its synchronous interface capabilities and wide voltage tolerance. The TQFP-128 package requires appropriate PCB footprint design. Given the discontinuation, alternative solutions with similar depth and width configurations should be evaluated. Compatibility checks for control logic and timing parameters are essential when migrating to newer generations of FIFO memory devices.

FIFOs Memory Part Context

The 72V3650 series belongs to Renesas' high-performance synchronous FIFO family, designed for complex system integration. These devices facilitate efficient data transfer between components operating at different speeds. The L15 suffix typically denotes specific timing characteristics within the lineup. This series supports various industrial and commercial applications requiring robust data handling capabilities.

FIFOs Memory Replacement Considerations

Official substitutes include the IDT72V3650L15PF. Engineers should verify pinout compatibility and electrical specifications before substitution. Migration guides provided by the manufacturer may assist in transitioning to newer memory technologies.
