72V811L20TFG

FIFOs Memory Overview

The 72V811L20TFG is an asynchronous dual-clock first-in, first-out (FIFO) memory device manufactured by Renesas Electronics. It features a storage organization of 4K words by 18 bits, providing a total capacity of 72 kbit. The component supports a maximum clock frequency of 50 MHz with a typical access time of 20 ns. It operates within a supply voltage range of 3.0 V to 3.6 V and functions across an industrial temperature range from -40°C to +85°C. The device is housed in a 64-pin Thin Quad Flat Package (TQFP).

FIFOs Memory Feature Summary

• Supports independent read and write clocks for flexible data buffering applications.
• Provides programmable almost-empty and almost-full flags for system monitoring.
• Features output enable control to place the data bus in a high-impedance state.

FIFOs Memory Applications

• Data buffering in optical disk controllers
• Interprocessor communication interfaces
• Local Area Network (LAN) systems

FIFOs Memory Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm package type and lead-free compliance requirements against specific project standards before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this part when a 18-bit wide asynchronous FIFO buffer is required. Ensure the design accommodates the 3.3V logic levels and TQFP-64 footprint constraints while meeting the specified industrial temperature operating range.

FIFOs Memory Part Context

This component belongs to the 72V811 series of high-performance FIFO memories. It serves as a specialized data storage solution designed for high-speed interface bridging and temporary data holding in complex digital signal processing and communication architectures.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the same family or verify functional equivalents with matching 18-bit width and 4K depth specifications if this specific suffix is unavailable.
