72205LB10TFI

Overview

The Renesas Electronics Corporation 72205LB10TFI is a synchronous FIFO memory device with a capacity of 256 x 18 bits. It operates at a data rate of 100MHz and features an access time of 6.5ns. The component supports unidirectional bus direction and is housed in a 64-TQFP package (10x10mm). It functions within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 60mA. The device includes programmable flags for status monitoring.

Feature Summary

• Synchronous operation supporting high-speed data buffering
• Programmable flag outputs for full and empty status indication
• Daisy-chain expansion capability for increased memory depth

Applications

• High-speed data buffering in digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Data storage in telecommunications equipment

Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status as older variants may differ. Check for End-of-Life notices or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a 256-word by 18-bit synchronous buffer is required. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 64-TQFP package constraints for PCB layout and thermal management requirements.

Part Context

This part belongs to the 72205LB series of synchronous FIFOs from Renesas. It shares architectural similarities with other members like the 72235LB and 72245LB, differing primarily in memory depth and package options. The series is designed for high-performance data handling applications.

Replacement Considerations

Direct substitutes include IDT72205LB10TFI. Verify pin compatibility and electrical parameters before substitution.
