72205LB15TFI8

Overview

The Renesas 72205LB15TFI8 is a synchronous FIFO memory device with a 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 data rates up to 66.7 MHz with a 10 ns access time. The component features unidirectional bus directionality and programmable status flags. It is housed in a 64-TQFP package (10x10 mm) and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Synchronous operation with simultaneous read and write capabilities controlled by clock signals
• Programmable status flags for monitoring full, empty, and half-full conditions
• Unidirectional data flow architecture designed for rate buffering applications

Applications

• Data buffering in multiprocessing systems
• Rate matching between asynchronous data sources
• Interface bridging in high-speed digital circuits

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as packaging variations exist. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Check for active obsolescence notices or end-of-life declarations prior to finalizing procurement plans.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO is required for system integration. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage requirements. Verify that the 64-pin TQFP footprint aligns with the target PCB layout constraints and thermal management specifications.

Part Context
