72T18125L4-4BBG

FIFOs Memory Overview

The Renesas 72T18125L4-4BBG is a TeraSync FIFO memory device with a storage capacity of 9 Mbit, organized as 1M x 9 or 512K x 18. It supports asynchronous and synchronous timing modes with a maximum clock frequency of 225 MHz and an access time of 3.4 ns. The component operates on a 2.5V supply voltage ranging from 2.375 V to 2.625 V, with a maximum power current of 70 mA. It features a unidirectional bus orientation and contains two circuits within a single package.

• Includes programmable flags accessible via serial or parallel means

FIFOs Memory Applications

• Network buffering applications
• Video signal processing systems
• Telecommunications equipment
• Data communications interfaces

FIFOs Memory Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Production has ceased, and the part is no longer available for new orders. Verification of availability should focus on remaining stock from authorized distributors or secondary market suppliers. Designers must confirm the authenticity of existing inventory due to the discontinued status.

FIFOs Memory Selection Notes

Selection requires evaluating the specific timing requirements against the 225 MHz maximum clock frequency and 3.4 ns access time. The 2.5V core voltage and 70 mA maximum current consumption must align with system power budgets. Designers should verify that the 1M x 9 or 512K x 18 organization meets the necessary buffer depth and width constraints for the target application.

FIFOs Memory Part Context

The 72T18125 series belongs to Renesas' TeraSync family of high-performance FIFO memories. These devices are engineered for applications requiring large data buffering and bus matching between disparate data widths. The series typically offers First Word Fall Through (FWFT) mode and standard IDT timing modes for flexible integration into complex digital systems.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct replacements may require functional equivalents from other manufacturers or redesigning the system around newer generation components.
