72245LB10TF

Overview

The Renesas 72245LB10TF is a synchronous FIFO memory device with a capacity of 4K x 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 100 MHz. The component features a 6.5 ns access time and utilizes a 64-TQFP (10x10) surface-mount package. It is classified as obsolete and no longer manufactured.

Feature Summary

• Synchronous first-in, first-out memory architecture for data buffering
• Uni-directional bus configuration
• Surface-mount TQFP packaging

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic domains
• Signal processing pipeline staging

Procurement Notes

This component is officially discontinued and obsolete. Verify availability through secondary market channels or authorized distributors handling surplus stock. Confirm RoHS compliance status and moisture sensitivity level prior to procurement, as original manufacturing specifications may vary in legacy inventory.

Selection Notes

Select this part only if the specific 4K x 18 depth and 18-bit width are required. Ensure the design accommodates the 64-TQFP footprint and 4.5V-5.5V power requirements. Consider alternative active series components if long-term supply stability is critical for the product lifecycle.

Part Context
