72225LB25TF

Overview

The Renesas 72225LB25TF is a synchronous FIFO memory device with a capacity of 18K bits, organized as 1K words by 18 bits. It supports unidirectional data transfer at a maximum clock frequency of 40MHz with an access time of 15ns. The component operates on a single 5V supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 60mA. It features programmable flags for status monitoring and is housed in a 64-pin TQFP package measuring 10x10mm. The device functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Synchronous operation with dedicated read and write clocks for reliable data buffering
• Programmable full and empty flags for precise buffer status monitoring
• Unidirectional data bus architecture simplifying interface design

Applications

• Data buffering in high-speed serial communication interfaces
• Interprocessor communication between microcontrollers and peripherals
• Network packet buffering in local area network equipment

Procurement Notes

Verify the specific suffix TF against official Renesas documentation to confirm the exact package dimensions and moisture sensitivity level. Confirm RoHS compliance status as historical records indicate potential non-compliance for older batches. Check for active discontinuation notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO is required for unidirectional data flow. Ensure the system clock does not exceed 40MHz to maintain the specified 15ns access time. Verify that the 5V logic levels match the host system requirements and that the 64-TQFP package fits the available PCB footprint constraints.

Part Context

This part belongs to the IDT 72225 series of synchronous FIFOs, designed for high-performance data buffering applications. The 72225 variant specifically offers 1K x 18 organization, distinguishing it from other members in the family that may offer different depths or widths. It represents a standard solution for managing data rate mismatches in digital systems.

Replacement Considerations

Consult official Renesas substitution guides for direct pin-compatible alternatives. Verify electrical compatibility including voltage ranges and timing parameters before integrating any substitute components into the existing design.
