72265LA15PFI8

Overview

The 72265LA15PFI8 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 supports a maximum data rate of 66.7MHz with a 10ns access time. It operates on a single 3V to 3.6V supply voltage and draws a maximum current of 55mA. The device utilizes a 64-pin TQFP package (10x10mm) and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports unidirectional data transfer with independent read and write clocks for simultaneous operations.
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full status signaling.
• Features fixed low first-word data latency and auto power-down capability to minimize standby consumption.

Applications

• Networking equipment buffer applications
• Video signal processing systems
• Telecommunications data buffering
• General-purpose data communications interfaces

Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm package dimensions and moisture sensitivity level. Confirm RoHS compliance status as sources indicate non-compliance for this variant. Check for end-of-life notices or obsolescence warnings prior to procurement decisions.

Selection Notes

Select this component when a 16K x 18 word depth is required for synchronous buffering. Ensure the design accommodates the 3.3V logic level requirements. Verify that the 64-TQFP footprint fits the PCB layout constraints compared to larger 14x14mm packages found in other series members.

Part Context

This part belongs to the 72V265 SuperSync FIFO family, designed as a low-power alternative to the 5V 722x5 series. It maintains functional compatibility while operating at 3.3V. The device eliminates the frequency select pin, simplifying clock management between RCLK and WCLK inputs.

Replacement Considerations

Consider the 72V265LA15TFGI8 for identical electrical specifications but with a smaller 10x10mm TQFP package. Verify pinout compatibility before substitution.
