72265LA15TFI8

Overview

The Renesas Electronics Corporation 72265LA15TFI8 is a SuperSync FIFO memory device with a storage capacity of 288K bits, organized as 16K words by 18 bits. It operates on a single 3.3V supply voltage and supports a maximum data rate of 66.7MHz with a cycle time of 10ns. The component features independent read and write clocks, allowing simultaneous operations. It 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

• Supports independent read and write clocks for simultaneous data handling
• Features fixed, low first word data latency time
• Includes programmable Almost-Empty and Almost-Full flags
• Provides auto power down capability to minimize standby power consumption

Applications

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

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations exist within the 72V265LA family. Confirm moisture sensitivity level and lead-free status requirements for your assembly process. Check current product lifecycle status, as this specific part number may be discontinued or subject to change. Ensure compatibility with 3.3V logic levels and verify package dimensions match your PCB footprint design.

Selection Notes

Select this component when a synchronous FIFO with 18-bit width and 16K depth is required. It is suitable for designs needing independent clock domains for read and write operations. Consider its 3.3V operation for low power applications. Verify that the 64-pin TQFP package fits your board space constraints. Compare performance metrics against other SuperSync FIFO variants if higher density or different bus widths are needed.

Part Context

This component belongs to the IDT/Renesas SuperSync FIFO family, designed for high-performance buffering. It is functionally compatible with the older 5V 722x5 family but optimized for 3.3V operation. The 72V265 series typically includes variants with different access times and package options. This specific model represents a standard speed version within the 16K x 18 organization category.

Replacement Considerations

Check for direct pin-compatible replacements within the 72V265LA series, such as those with different access times (e.g., 10ns vs 15ns). Verify functional compatibility with existing 5V family designs if migrating from older parts. Consult Renesas for end-of-life notices and recommended alternative part numbers.
