72205LB15TF

Overview

The Renesas 72205LB15TFI is a synchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 256 words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 66.7 MHz. The component features a 10 ns access time and unidirectional bus directionality. It is housed in a 64-TQFP (10x10) surface-mount package and functions across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with clocked read and write controls for precise data buffering
• Supports programmable flags to indicate full and empty buffer states
• Unidirectional data flow architecture optimized for interprocessor communication

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the exact suffix against official documentation, as the provided model lacks the final character found in distributor listings. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Check for active obsolescence notices or product change notifications from the manufacturer before procurement planning.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO with high-speed 66.7 MHz performance is required. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range and the -40°C to 85°C operating temperature. Verify that the 64-TQFP package dimensions fit the target PCB layout constraints.

Part Context
