72225LB10TFG

Overview

The Renesas 72225LB10TFG is a synchronous FIFO memory device with a capacity of 18K organized as 1K x 18 bits. It operates at a maximum data rate of 100MHz with a typical access time of 6.5ns. The component supports unidirectional bus direction and is powered by a single 4.5V to 5.5V supply voltage, drawing a maximum current of 60mA. It features programmable flags for status monitoring and is housed in a 64-TQFP (10x10) surface-mount package.

Feature Summary

• Synchronous first-in-first-out memory architecture for efficient data buffering
• Programmable flag support for managing full and empty buffer states
• Unidirectional data transfer capability optimized for specific interface directions

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock domains
• Temporary storage in telecommunications equipment data streams

Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for end-of-life notices or obsolescence warnings before finalizing design integration. Ensure the selected package variant matches your PCB footprint constraints.

Selection Notes

Select this component when a 1K x 18 word depth is required for synchronous buffering applications. Consider the 100MHz speed rating for high-throughput data paths. Evaluate the 64-TQFP package size against available board space. Compare power consumption characteristics against alternative FIFO families if low-power operation is critical.

Part Context

This part belongs to the Renesas 72225LB series of synchronous FIFOs. The series offers various depths and speeds within the same package family. The 72225LB10 variant specifically targets 100MHz performance levels. It shares architectural similarities with other members of the 7200 series but differs in memory organization and timing parameters.

Replacement Considerations

Check for direct cross-reference part numbers from IDT or Renesas legacy lists. Verify compatibility with existing firmware logic controlling read/write pointers. Ensure replacement parts maintain the same 64-TQFP footprint and pin configuration.
