72205LB15TF8

Overview

The Renesas Electronics Corporation 72205LB15TF8 is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 4.5K organized as 256 words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 60mA. The device is housed in a 64-TQFP package measuring 10x10mm and is rated for industrial operating temperatures from -40°C to 85°C.

Feature Summary

• Synchronous first-in-first-out memory architecture supporting clocked read and write operations
• Configurable programmable status flags for monitoring buffer levels
• Expansion capability allowing depth and width adjustments

Applications

• Data buffering in multiprocessing systems
• Rate matching between asynchronous components
• Interprocessor communication interfaces

Procurement Notes

Verify part authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the component may not meet current environmental standards. Validate package integrity upon receipt to ensure suitability for surface mount assembly processes.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO is required. Ensure the design accommodates the 64-pin TQFP footprint. Verify that the 4.5V to 5.5V supply range aligns with system power rails. Consider the 10ns access speed for timing constraints.

Part Context

This device is part of the IDT 72205LB family of high-speed synchronous FIFOs. It shares functional compatibility with other members of the 722xxLB series, differing primarily in memory density and speed grades. The LB suffix typically denotes low-power CMOS technology optimized for performance.
