72V2111L15PFI

FIFOs Memory Overview

The 72V2111L15PFI is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It features a storage organization of 512 words by 9 bits, providing a total capacity of 4.5 Kbits. The component supports a maximum clock frequency of 66.7 MHz with a typical access time of 10 ns. It operates on a single 3.3 V power supply within the range of 3.0 V to 3.6 V and draws a maximum supply current of 20 mA. The device utilizes a unidirectional data bus architecture and is housed in a 64-pin Thin Quad Flat Package (TQFP-64).

FIFOs Memory Feature Summary

• Synchronous FIFO architecture with independent read and write clock controls for flexible data buffering.
• Configurable status flags including full, empty, and half-full indicators for system monitoring.
• Supports both single-clock and dual-clock asynchronous operation modes.
• Integrated programmable flag logic for customized status reporting.

FIFOs Memory Applications

• Data buffering in graphics processing systems.
• Interprocessor communication interfaces.
• Local area network (LAN) data handling.

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status as indicated in official documentation, noting that specific variants may not meet current environmental standards. Check moisture sensitivity levels and reflow soldering profiles prior to assembly to ensure reliability during manufacturing processes.

FIFOs Memory Selection Notes

Select this component when a 512x9 synchronous FIFO with 66.7 MHz performance is required. Ensure the design accommodates the 3.3 V logic level and TQFP-64 package constraints. Consider thermal dissipation requirements given the 20 mA maximum supply current. Verify interface compatibility with target microprocessors or FPGAs regarding clock domain crossing and flag signaling protocols.

FIFOs Memory Part Context

This part belongs to the Renesas 72V2111 series of synchronous FIFO memories. The series offers various densities and speeds tailored for high-performance data buffering applications. The 72V2111 variant specifically targets 3.3 V systems requiring reliable unidirectional data flow with configurable status flags for efficient system integration.

FIFOs Memory Replacement Considerations

Check for pin-compatible alternatives within the same 72V family or cross-reference with IDT equivalents. Verify electrical parameters such as access time and voltage ranges match application requirements before substitution.
