72245LB15TFI

Overview

The Renesas 72245LB15TFI is a synchronous FIFO memory integrated circuit featuring an 18K storage capacity organized as 1K x 18 bits. It operates with a maximum data rate of 66.7MHz and a 10ns access time. The device supports unidirectional bus direction and accepts a supply voltage between 4.5V and 5.5V, with a maximum supply current of 60mA. It is housed in a 64-TQFP (10x10) surface-mount package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Synchronous operation with independent read and write clock controls for flexible data buffering
• Programmable status flags including empty, full, almost-empty, and almost-full indicators
• Supports depth and width expansion for customized memory configurations
• Output enable pin places the output data bus in a high-impedance state

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity and moisture sensitivity level handling procedures before assembly. Check for available replacement alternatives from the manufacturer's current portfolio.

Selection Notes

Select this component when a 1K x 18 synchronous FIFO with 10ns speed is required. Ensure system voltage matches the 4.5V to 5.5V operating range. Consider the 64-TQFP package constraints for PCB layout. Verify that unidirectional data flow meets application needs compared to bidirectional alternatives.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFO memories. It serves as a specialized buffer solution for high-speed digital interfaces. The device provides reliable data storage with programmable status flags to manage flow control effectively in complex electronic systems.
