72V261LA20TF

FIFOs Memory Overview

The 72V261LA20TF is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 16K words by 9 bits. The component supports a maximum data rate of 50MHz with an access time of 12ns. It operates on a single power supply voltage ranging from 3V to 3.6V and draws a maximum supply current of 55mA. The device utilizes a unidirectional bus interface and is housed in a 64-pin TQFP package measuring 14x14mm. It is designed for surface mount installation and functions within an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports independent read and write clocks allowing simultaneous operations
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full states
• Features fixed low first word data latency for retransmit operations
• Capable of depth and width expansion for system flexibility

FIFOs Memory Applications

• Data buffering in networking equipment
• Video signal processing systems
• Telecommunications infrastructure
• General data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix 'TF' against official Renesas documentation to confirm pinout and package dimensions match your design requirements. Confirm that the 0°C to 70°C commercial temperature grade aligns with your environmental specifications. Check for RoHS compliance status as older variants may not meet current regulations. Ensure the 64-TQFP footprint matches your PCB layout constraints before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 16K x 9 organization and 50MHz performance is required. It serves as a functional equivalent to the 5V 72261 family but operates at 3.3V for lower power consumption. Consider this part if independent read/write clocks are necessary for asynchronous data transfer between domains. Verify that the 12ns access time meets your system timing constraints.

FIFOs Memory Part Context

This device belongs to the Renesas 72V SuperSync FIFO family, which provides high-performance buffering solutions. The 72V series is designed to replace older 5V logic families while offering improved power efficiency. The 72V261 variant specifically targets applications requiring moderate density and speed. It maintains pin compatibility with related devices in the 72V2x1 series for easier migration.
