72245LB25PFI8

Overview

The Renesas Electronics Corporation 72245LB25PFI8 is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 18K bits, organized as 1K words by 18 bits. The component supports a maximum data rate of 40MHz with an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-LQFP surface-mount package.

Feature Summary

• Synchronous first-in, first-out memory architecture for efficient data buffering
• Supports unidirectional bus direction for dedicated input/output flow
• Includes programmable flags to indicate status conditions

Applications

• Data buffering in high-speed digital systems
• Interface bridging between components operating at different clock speeds
• Temporary storage in communication protocols requiring reliable data transfer

Procurement Notes

This component is officially designated as End-of-Life (EOL) by Renesas Electronics. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturer channels. Buyers must confirm the authenticity of the source and check for moisture sensitivity level compliance before procurement, as standard packaging may not be guaranteed for discontinued items.

Selection Notes

Engineers selecting this part should verify that the 1K x 18 word depth meets system requirements, as larger capacities exist within the same family. The 15ns access time and 40MHz speed are suitable for moderate-frequency applications. Ensure the design accommodates the 64-pin LQFP footprint and the specific 4.5V to 5.5V power supply constraints defined in the datasheet.

Part Context

The 72245LB25PFI8 is part of the Renesas 7200 series of synchronous FIFO memories. This series provides versatile buffering solutions for various electronic applications. The 'LB' suffix typically denotes low-power bipolar technology, while '25' indicates the 15ns speed grade. The 'PFI8' suffix specifies the 64-pin plastic leaded chip carrier or TQFP package variant with industrial temperature rating capabilities.
