72225LB25J

Overview

The 72225LB25J is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 18K bits, organized as 1K words by 18 bits. The component supports unidirectional data transfer with a maximum clock frequency of 66.7 MHz and an access time of 10 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 60 mA. The device is housed in a 64-TQFP surface-mount package.

Feature Summary

• Synchronous operation with dedicated read and write clocks for precise data buffering
• Programmable status flags indicating full, empty, and half-full conditions
• Unidirectional bus architecture supporting high-speed data transfer
• Integrated control logic for simple interface implementation

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous logic domains
• Network communication equipment data handling
• Graphics controller memory buffering

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards as the part may not meet current environmental directives. Validate package dimensions and pinout compatibility during integration planning. Check for moisture sensitivity level constraints during storage and handling procedures.

Selection Notes

Select this component when synchronous timing alignment is required for 18-bit wide data paths. Consider the 10 ns access speed for applications demanding low latency. Evaluate the 64-TQFP package suitability for available PCB real estate. Ensure power supply stability within the specified voltage range to maintain reliable operation under varying load conditions.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs. It shares architectural similarities with other members like the 72235LB25J but differs in depth and package configuration. The series is designed for general-purpose memory buffering tasks requiring deterministic timing characteristics in industrial and commercial electronic systems.

Replacement Considerations

Public confirmed substitute part numbers include IDT72225LB25J.
