72225LB10PFG8

Overview

The Renesas Electronics Corporation 72225LB10PFG8 is a synchronous FIFO memory device operating within the 7200 series. It features a storage capacity of 18K bits, organized as 1K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates on a single 4.5V to 5.5V power supply and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP (14x14) surface-mount package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with programmable flags for status monitoring
• Unidirectional bus direction supporting standard FIFO logic
• Surface-mount installation in a compact 64-pin TQFP package

Applications

• High-speed data buffering between asynchronous system domains
• Interface bridging in digital signal processing architectures
• Temporary data storage in communication protocol converters

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements against specific project regulations, as original variants may not meet current environmental standards. Validate package dimensions and pinout compatibility during integration planning. Review official product change notices for any manufacturing site or material updates that may affect long-term supply chain stability.

Selection Notes

Select this component when a 1K x 18 word depth is required for synchronous data handling. Ensure the design accommodates the 4.5V to 5.5V voltage range and 60mA current consumption. Verify that the 64-TQFP footprint matches the PCB layout constraints. Consider thermal management capabilities within the 0°C to 70°C operating envelope for the intended application environment.

Part Context

This part belongs to the Renesas 7200 series of high-performance FIFO memories. It succeeds earlier IDT designs following corporate acquisitions. The 72225 variant specifically targets applications requiring moderate depth with wide data paths. It shares architectural similarities with other members of the family but offers distinct speed and configuration parameters tailored for specific interface needs.

Replacement Considerations

The 72225LB10PFG is listed as an upgrade alternative from Renesas. Verify electrical parameter equivalence before substitution. Check for any mechanical differences in the 64-TQFP package. Confirm software or firmware compatibility if the FIFO controls are integrated into the host system logic.
