72265LA15TF8

Overview

The 72265LA15TF8 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 per word. The component supports a maximum data rate of 66.7MHz with a cycle time of 10ns. It operates on a single 3.3V supply voltage and draws a maximum supply current of 55mA. The device is housed in a 64-pin TQFP package measuring 10x10mm and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides unidirectional data buffering with independent read and write clock controls for simultaneous operations.
• Features fixed low first-word data latency and retransmit operation capabilities.
• Includes programmable Almost-Empty and Almost-Full flags alongside standard Empty, Full, and Half-Full status indicators.
• Supports auto power down mode to minimize standby power consumption.

Applications

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

Procurement Notes

Verify the specific suffix TF8 against official Renesas documentation to confirm package dimensions and moisture sensitivity level. Confirm RoHS compliance status as manufacturing sites or standards may vary. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure the supplier provides valid traceability documents for this discontinued series component.

Selection Notes

Select this component when a 3.3V synchronous FIFO with 18-bit width is required. It serves as a functionally compatible replacement for the 5V 72265 family while offering lower power consumption. Verify that the 66.7MHz speed meets system timing requirements. Ensure the design accommodates the 64-pin TQFP footprint and industrial temperature range specifications.

Part Context

This part belongs to the 72V265 SuperSync FIFO family, designed for high-performance data buffering. It maintains functional compatibility with the older 5V 722x5 series but operates at 3.3V. The removal of the Frequency Select pin simplifies clocking configurations compared to previous generations.

Replacement Considerations

The 72V265LA15PFI8 is a documented alternative within the same family. Verify pinout compatibility and package differences before substitution.
