72261LA20TF8

Overview

The 72261LA20TF8 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 3V to 3.6V power supply and draws a maximum current of 55mA. The device is housed in a 64-TQFP package (14x14mm) and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with independent read and write clocks
• Supports programmable Almost-Empty and Almost-Full flags
• Includes FWFT (First Word Fall Through) capability
• Uni-directional bus architecture

Applications

• Data buffering in telecommunications systems
• Video signal processing applications
• Networking equipment data flow management
• General-purpose data communications interfaces

Procurement Notes

Verify the exact suffix TF8 against official Renesas documentation to confirm the specific tape-and-reel packaging configuration. Confirm RoHS compliance status as sources indicate non-compliance for this variant. Check for End-of-Life (EOL) notifications or Product Discontinuance Notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a uni-directional synchronous FIFO with 16K x 9 organization is required. Ensure the system design accommodates the 3V to 3.6V voltage range and 55mA maximum current consumption. Verify that the 64-TQFP package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the 72V261 series of SuperSync FIFOs. It is functionally compatible with the older 5V 72261 family but operates at lower voltage levels. The device is designed for high-speed data buffering where clock domain crossing is necessary between asynchronous system components.

Replacement Considerations

Official cross-reference tools may list IDT72261LA20TF8 as a substitute. Verify pin compatibility and electrical specifications with the manufacturer's datasheet before substitution.
