72215LB10TF8

Overview

The 72215LB10TF8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 512 x 18 bits, organized as 512 words with an 18-bit data width. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 100 MHz. It utilizes a 64-pin TQFP package and is designed for surface-mount installation.

Feature Summary

• Synchronous first-in, first-out architecture with dedicated read and write clock inputs
• Uni-directional bus interface supporting 18-bit data transfer widths
• Integrated programmable status flags for empty and full conditions

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock domains
• Temporary storage in telecommunications network equipment

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability or discontinuation. Verification of current stock status and alternative sourcing strategies is required before procurement planning. Compliance with RoHS directives should be confirmed against specific manufacturing dates due to legacy status.

Selection Notes

Engineers selecting this part must account for its discontinued lifecycle status. Design reviews should prioritize verifying long-term supply chain stability or identifying equivalent successors from the same family. Electrical compatibility checks regarding the 4.5 V to 5.5 V supply range and 100 MHz speed are essential for existing system integration.

Part Context

The 72215LB10TF8 belongs to the 72215LB series of synchronous FIFOs. This series is characterized by high-speed operation and flexible configuration options for data width and depth. The device represents a legacy solution in Renesas's memory portfolio, previously widely used in networking and industrial applications requiring reliable data buffering.
