72245LB10PFGI8

Overview

The Renesas 72245LB10PFGI8 is a synchronous FIFO memory device with a storage capacity of 72K bits, organized as 4K words by 18 bits. It operates at a data rate of 100MHz with a 6.5ns access time. The component supports unidirectional bus direction and accepts a supply voltage between 4.5V and 5.5V. Maximum supply current is 60mA. It features programmable flags and is housed in a 68-PLCC package.

Feature Summary

• Synchronous first-in, first-out memory architecture for data buffering
• Supports high-speed operation up to 100MHz clock frequency
• Includes programmable status flags for flow control management

Applications

• Data buffering in optical disk controllers
• Local Area Network (LAN) interface buffering
• Interprocessor communication systems

Procurement Notes

Verify the End-of-Life (EOL) status via official Renesas Product Change Notices before design finalization. Confirm that the 68-PLCC package dimensions match the target PCB footprint. Ensure the 4.5V to 5.5V supply range aligns with system power rails. Check RoHS3 compliance requirements against project specifications.

Selection Notes

Select this part when a 4K x 18 word depth is required for synchronous data buffering. The 100MHz speed suits high-throughput interfaces. Verify compatibility with existing logic levels within the specified voltage range. Consider the 68-pin PLCC package constraints during mechanical layout planning.

Part Context

This component belongs to the Renesas 7200 series of synchronous FIFO memories. It serves as a specialized buffer for managing data transfer rates between asynchronous or mismatched speed components. The 72245 variant specifically provides 72K bit density with 18-bit wide data paths.

Replacement Considerations

Consult official Renesas documentation for qualified substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before substitution.
