72265LA20TFI

Overview

The Renesas 72265LA20TFI is a SuperSync First-In-First-Out (FIFO) memory device with an organization of 16K words by 18 bits, providing a total storage capacity of 288 kbit. It operates on a single 3.3V supply voltage and features independent read and write clocks to allow simultaneous data transfer. The component supports a maximum clock frequency of 100 MHz with a 20 ns access time. It utilizes LVTTL I/O levels and is housed in a 64-pin Thin Quad Flat Package (TQFP).

Feature Summary

• SuperSync architecture enabling independent read and write clock domains for simultaneous operation.
• Fixed low first word data latency (FWFT) mode for reduced processing delay.
• Auto power down functionality to minimize standby power consumption.
• Programmable Almost-Empty and Almost-Full flags for precise buffer management.

Applications

• Networking equipment requiring high-speed data buffering.
• Video signal processing and transmission systems.
• Telecommunications infrastructure interfaces.
• High-performance data communications applications.

Procurement Notes

Verify the specific suffix 'TFI' against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as legacy components may vary. Check current lifecycle status, as this part may be discontinued or subject to last-time buy restrictions. Ensure design-in compatibility with existing PCB footprints for the 64-pin TQFP package.

Selection Notes

Select this component when a 3.3V synchronous FIFO with 18-bit width is required. It is suitable for designs needing independent clock domains and fixed latency. Compare against the 5V 72265 family if voltage compatibility differs. Consider the 72V265 series for potential pin-compatible alternatives within the same product line.

Part Context

This component belongs to the Renesas SuperSync FIFO family, designed for high-throughput data buffering. It serves as a functional equivalent to older 5V devices but optimized for lower power consumption at 3.3V. The 72265 series is widely used in industrial and commercial applications demanding reliable asynchronous-to-synchronous data conversion.

Replacement Considerations

Official substitutes include the IDT72265L20TFI and the 72V265LA20TFI. Verify that the replacement maintains the 18-bit width and 16K depth. Ensure the new part supports the required 3.3V operating voltage and 100 MHz performance.
