72225LB15J8

Overview

The Renesas Electronics Corporation 72225LB15J8 is a synchronous FIFO memory device with a capacity of 1K x 18 bits, totaling 18 kilobits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 40 MHz with an access time of 15 ns. The component features unidirectional bus directionality and programmable flags for status monitoring. It is housed in a 68-PLCC package with dimensions of 24.21x24.21 mm and is designed for surface mount installation.

Feature Summary

• Synchronous first-in-first-out memory architecture for reliable data buffering
• Programmable flag support for advanced status indication
• Unidirectional data bus configuration

Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status as historical records may vary. Check for end-of-life notices or obsolescence warnings before procurement planning. Ensure moisture sensitivity level requirements are met during storage and handling procedures.

Selection Notes

Select this component when a 1K x 18 synchronous FIFO is required with 15 ns access speed. Compare against the LB15PFI variant if higher 66.7 MHz speeds or TQFP packaging are needed. Verify that the 68-PLCC footprint matches the target PCB design constraints. Ensure the 4.5 V to 5.5 V operating voltage aligns with the system power rails.

Part Context

This part belongs to the Renesas 72225 series of synchronous FIFOs, which are designed for high-speed data buffering applications. The series offers various configurations in terms of speed, organization, and package types to suit different system requirements. The 72225LB15J8 specifically provides a balance of moderate speed and standard industrial voltage operation.

Replacement Considerations

The IDT72225LB15J8 is a confirmed substitute part number for this component.
