72V225L15TF8

FIFOs Memory Overview

The 72V225L15TF8 is a synchronous first-in, first-out (FIFO) memory device manufactured by Renesas Electronics. It features an 18-bit data bus width and a storage organization of 1K x 18, resulting in a total capacity of 18 kilobits. The component supports a maximum clock frequency of 66.7 MHz with a typical access time of 10 ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum power consumption of 30 mA. The device is housed in a 64-pin TQFP package and is designed for surface mount installation.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) timing mode for reduced latency
• Includes programmable Almost-Empty and Almost-Full flags for buffer management
• Features unidirectional data flow architecture
• Provides 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) data handling

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status as indicated in official documentation, noting that specific suffixes may affect regulatory adherence. Check for moisture sensitivity level requirements during storage and handling to prevent damage. Ensure the ordering part number matches the exact electrical and mechanical specifications required for the target design.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 18-bit width and 1K depth is required. It is suitable for designs needing 66.7 MHz operation speeds and 10 ns access times. Consider the 64-pin TQFP package for surface mount applications. Verify compatibility with 3.3V logic levels and ensure the system can accommodate the specified power consumption and temperature operating range.

FIFOs Memory Part Context

This part belongs to the Renesas 72V2x5 series of synchronous FIFO memories. The series offers various densities and bus widths, all sharing common interface characteristics and timing parameters. The 72V225 variant specifically targets applications requiring moderate data buffering capabilities with fast access times, fitting between smaller and larger capacity options in the product line.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the 72V2x5 family, such as the 72V245L15TFGI for higher density or 72V205L15TF8 for lower density, ensuring pinout and electrical compatibility. Verify if older IDT-branded equivalents are available if the Renesas designation causes sourcing issues.
