72225LB15PFGI

Overview

The Renesas 72225LB15PFGI is a synchronous FIFO memory device with a capacity of 18K bits, organized as 1K x 18. It operates at a maximum data rate of 66.7MHz with a 10ns access time. The component supports unidirectional bus direction and programmable flags. It functions within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 60mA. The device is housed in a 64-TQFP (14x14) surface-mount package and operates across a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with high-speed data transfer capabilities up to 66.7MHz
• Configurable depth and width organization for flexible memory mapping
• Integrated programmable status flags for buffer management
• Wide operating temperature range suitable for industrial environments

Applications

• High-speed data buffering in telecommunications systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage
• Digital signal processing pipeline staging

Procurement Notes

Verify the specific suffix 'GI' against official Renesas documentation to confirm lead-free compliance and RoHS status, as standard variants may differ. Confirm availability status as this series may be subject to discontinuation notices. Ensure the 64-TQFP package dimensions match your PCB footprint requirements precisely before ordering.

Selection Notes

Select this component when a 1K x 18 word depth is required for synchronous data buffering. The 10ns access time suits applications needing moderate speed without the complexity of SRAM controllers. Consider the 5V supply requirement and ensure power rails align with system design constraints compared to lower voltage alternatives.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs, originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas. The 72225 variant specifically targets applications requiring 18-bit wide data paths. The family is known for providing reliable first-in-first-out memory structures for digital interface applications.
