72265LA10TF8

Overview

The 72265LA10TF8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 288K bits, organized as 16K words by 18 bits. The component operates with a 10ns read/write cycle time and supports data rates up to 100MHz. It utilizes a single 3.3V power supply and includes independent read and write clocks for simultaneous operation. The device is housed in a 64-pin TQFP package.

Feature Summary

• Supports SuperSync architecture with fixed, low first word data latency
• Features programmable Almost-Empty and Almost-Full flags for status signaling
• Enables retransmit operations with independent read and write clock domains
• Includes auto power down functionality to minimize standby power consumption

Applications

• Networking equipment buffering
• Video signal processing systems
• Telecommunications data handling
• Data communications interfaces

Procurement Notes

Verify the exact part number spelling, as official documentation primarily lists the IDT72265LA10TF8 variant. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check current lifecycle status as older components may be discontinued or subject to last-time buy restrictions. Ensure packaging type matches design requirements.

Selection Notes

Select this component for applications requiring high-speed synchronous data buffering with low latency. Verify that the 3.3V supply voltage aligns with system power rails. Ensure the 18-bit bus width meets data path requirements. Consider thermal performance within the specified operating temperature range during PCB layout.

Part Context

This device belongs to the 722x5 family of SuperSync FIFOs, designed for low power consumption compared to earlier 5V versions. It maintains functional compatibility with legacy designs while offering improved performance metrics. The series is widely used in digital signal processing and communication infrastructure.

Replacement Considerations

The IDT72265LA10TF8 is a verified equivalent part number for this component. Other members of the 72V265 series may offer similar specifications but require verification of pinout and electrical characteristics before substitution.
