72205LB10TF8

Overview

The Renesas Electronics Corporation 72205LB10TF8 is a synchronous FIFO memory device housed in a 64-TQFP package. It features a storage capacity of 4.5K bits, organized as 256 x 18. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 60mA. The device includes programmable flags for status monitoring and functions across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with clocked read and write controls for reliable data buffering
• Programmable flag support enables custom status indication for full and empty conditions
• Unidirectional bus architecture simplifies interface design for specific data flow requirements

Applications

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

Procurement Notes

Verify the exact suffix TF8 against official Renesas documentation to confirm package dimensions and moisture sensitivity level. Confirm RoHS compliance status as sources indicate non-compliance. Check for end-of-life notices or obsolescence warnings before procurement planning. Ensure availability through authorized distributors given potential discontinuation risks associated with legacy IDT product lines.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 18-bit width is required. Compare against other members of the 72205LB10 series if different capacities or packages are needed. Verify that the 6.5ns access time meets system timing constraints. Consider the 64-TQFP footprint for PCB layout compatibility.

Part Context

This part belongs to the Renesas (formerly IDT) 72205LB10 family of high-speed synchronous FIFOs. These devices are designed for applications requiring efficient data buffering between asynchronous or synchronous domains. The 72205 variant specifically offers 256x18 organization, distinguishing it from other densities in the broader 722xx series lineup.

Replacement Considerations

Check for direct pin-compatible substitutes within the 72205LB10 series. Verify if newer generations from Renesas offer equivalent performance with updated compliance standards.
