72245LBTFI

Overview

The Renesas Electronics Corporation 72245LBTFI is a synchronous FIFO memory device with an organization of 4K x 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports unidirectional data transfer. The component features a 64-TQFP (10x10) surface-mount package and is rated for commercial operating temperatures from 0°C to +70°C. This specific part number is classified as obsolete.

Feature Summary

• Supports synchronous read and write operations for reliable data buffering
• Provides 4K x 18 bit storage capacity for high-width data applications
• Features programmable flags for status monitoring

Applications

• Data buffering in telecommunications systems
• Interface bridging between asynchronous logic domains
• High-speed data acquisition systems

Procurement Notes

This component is officially discontinued by the manufacturer. Verify end-of-life status through official Renesas notices before design finalization. Sourcing requires checking authorized distributors for remaining stock or identifying qualified replacement parts that meet identical electrical specifications.

Selection Notes

Select this part only if legacy compatibility is required. Ensure the system design accommodates the 64-TQFP package dimensions. Verify that the 4.5 V to 5.5 V supply range matches the target application power rails. Confirm that the 4K x 18 depth meets the buffer requirements.

Part Context

Part of the 7200 series synchronous FIFO family, designed for high-performance data storage. The 72245 variant specifically offers 18-bit word width, distinguishing it from narrower 9-bit or wider variants in the same series. It serves as a specialized memory interface solution for parallel data paths.

Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Identify equivalents within the 72245 series that match the 4K x 18 organization and 64-TQFP package. Verify pinout compatibility and electrical parameter alignment.
