72245LB10PFG8

Overview

The Renesas Electronics Corporation 72245LB10PFG8 is a synchronous FIFO memory device with a capacity of 4K x 18 bits. It operates at a data rate of 100MHz and features a 6.5ns access time. The component supports unidirectional bus direction and includes programmable flags for status monitoring. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 60mA. Designed for surface mount installation, it is housed in a 64-TQFP package.

Feature Summary

• Synchronous first-in, first-out memory architecture with clocked read and write controls
• Supports asynchronous or coincident read and write clock operations
• Includes programmable almost-empty and almost-full flags with default settings
• Output enable function places the output data bus in a high-impedance state

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures before assembly. Validate package integrity against the specified 64-TQFP dimensions. Ensure compatibility with existing system voltage levels ranging from 4.5V to 5.5V.

Selection Notes

Select this component when a 4K x 18 synchronous FIFO is required for 100MHz operation. Consider the 6.5ns access time for timing-critical interfaces. Evaluate the 64-TQFP package suitability for surface mount processes. Compare power consumption characteristics against alternative devices in the 7200 series family.

Part Context

This device belongs to the Renesas 7200 series of high-speed FIFO memories. It shares functional similarities with other members like the 72245LB10TF8 but differs in packaging and specific suffix designations. The series is designed for versatile data buffering needs across various industrial and commercial electronic applications.

Replacement Considerations
