72225LB10J

Overview

The Renesas Electronics Corporation 72225LB10J is a synchronous First-In, First-Out (FIFO) memory device belonging to the 7200 series. It provides a storage capacity of 18K 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 with a maximum current consumption of 60mA. The device is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 14mm x 14mm.

Feature Summary

• Synchronous FIFO architecture for reliable data buffering
• Programmable full and empty flags for status monitoring
• Wide 18-bit data bus width for high throughput
• Surface-mount TQFP packaging for compact integration

Applications

• Data buffering in local area network systems
• Interprocessor communication interfaces
• Graphics data handling applications

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level prior to assembly. Check for RoHS compliance variations across manufacturing lots. Validate pin compatibility with existing PCB footprints. Review datasheet revisions for any functional updates or warnings.

Selection Notes

Select this part when 18-bit wide synchronous buffering is required. Ensure system clock does not exceed 66.7MHz. Verify voltage levels match the 4.5V to 5.5V operating range. Consider the 64-TQFP footprint constraints during layout. Evaluate thermal dissipation requirements within the specified temperature range.

Part Context

This component is part of the Renesas 7200 series of synchronous FIFOs. It shares architectural similarities with other members like the 72225LB15PFI but differs in package type and speed grade. The series is designed for general-purpose data buffering tasks requiring deterministic latency and simple interface control.

Replacement Considerations
