72V255LA20TF

FIFOs Memory Overview

The 72V255LA20TF 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 on a single power supply voltage ranging from 3V to 3.6V and draws a maximum supply current of 55mA. The component is housed in a 64-TQFP package measuring 14x14mm and is designed for surface mount installation. It functions within an industrial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports unidirectional data transfer with independent read and write clocks.
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full conditions.
• Features fixed low first word data latency time for efficient buffering.
• Provides retransmit operation capability.

FIFOs Memory Applications

• Networking equipment requiring large data buffering
• Video signal processing systems
• Telecommunications infrastructure
• Data communications interfaces

FIFOs Memory Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct distribution channels. Confirm RoHS compliance status, as documentation indicates non-compliance with current regulations. Ensure compatibility with existing system designs before sourcing replacement units from alternative suppliers.

FIFOs Memory Selection Notes

Select this part when a synchronous FIFO with 18-bit width and 8K depth is required for 3.3V logic systems. It serves as a functional equivalent to the older 5V 722x5 family but operates at lower voltage. Consider the 64-TQFP package constraints and verify that the 10ns access time meets the system's timing requirements for high-speed data buffering applications.

FIFOs Memory Part Context

The 72V255LA20TF belongs to the 72V SuperSync FIFO series, which are designed for low-power, high-performance data buffering. This specific model is part of the 3.3V variant line, offering pin compatibility with other devices in the 72V2x5 family. It is engineered to replace older 5V components while providing improved power efficiency and faster cycle times for modern digital systems.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers include IDT72V255LA20TF. Verify pinout and electrical specifications against the original datasheet to ensure functional compatibility during replacement.
