72265LA20PFI

Overview

The Renesas Electronics 72265LA20PFI is a SuperSync FIFO memory device with a storage organization of 16K x 18 bits, providing a total capacity of 288 kbit. It operates on a 3.3V supply voltage and features an asynchronous interface with a maximum access time of 20 ns. The component is housed in a 64-pin TQFP package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports independent read and write clocks for simultaneous data operations
• Features fixed, low first word data latency time
• Includes programmable status flags for empty, full, half-full, almost-empty, and almost-full conditions
• Provides auto power down functionality to minimize standby power consumption

Applications

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

Procurement Notes

Verify the specific suffix PFI confirms the 64-pin TQFP package and industrial temperature grade. Confirm RoHS compliance status as documentation may vary by production batch. Check for End-of-Life notices or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a 3.3V synchronous FIFO with 18-bit width is required. Ensure the design accommodates the 64-pin TQFP footprint. Verify that the 20 ns access time meets system timing requirements for the intended data throughput.

Part Context

This part belongs to the 72V2x5 SuperSync FIFO family, designed as a functionally compatible version of the 5V 722x5 series but optimized for lower power consumption at 3.3V. It eliminates the need for frequency select pins between clock inputs.

Replacement Considerations

The IDT72265LA20PFI is a confirmed substitute part number.
