72V255LA15TFI

FIFOs Memory Overview

The 72V255LA15TFI is a synchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 8K words by 18 bits. The device supports a maximum data rate of 66.7MHz with an access time of 10ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 55mA. The component is housed in a 64-TQFP package measuring 10x10mm and is designed for surface mount installation.

FIFOs Memory Feature Summary

• Supports First-Word-Fall-Through (FWFT) functionality for immediate data availability upon read assertion.
• Includes programmable full and empty flags to facilitate precise buffer management and flow control.
• Provides signal relay capability to enable seamless interface bridging between different logic families or voltage domains.

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous clock domains
• Temporary data storage in telecommunications equipment

FIFOs Memory Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may indicate differences in packaging or temperature ratings. Confirm RoHS compliance status, as specific manufacturing lots may vary. Check for End-of-Life notices or obsolescence warnings prior to finalizing procurement plans to ensure long-term supply stability.

FIFOs Memory Selection Notes

Select this component when a 18-bit wide synchronous FIFO with 8K depth is required. Ensure the system operates within the 3V to 3.6V supply range. Verify that the 64-TQFP package dimensions fit the PCB layout constraints. Consider the 10ns access time relative to the system clock speed to guarantee timing margins are met.

FIFOs Memory Part Context

This part belongs to the 72V series of SuperSync FIFOs, which are functionally compatible with the older 5V IDT72255/72265 family. The 'LA' designation typically indicates enhanced performance or specific feature sets within the 3.3V operating range. The 'TFI' suffix denotes the tape and reel packaging format and specific thermal/mechanical characteristics.

FIFOs Memory Replacement Considerations

The 72V255L15TF is a pin-compatible alternative within the same series. Verify if the standard tray packaging of the L15 variant meets inventory requirements. Both parts share identical electrical specifications and functional compatibility.
