72225LB15PF8

Overview

The Renesas 72225LB15PF8 is a synchronous FIFO memory device with a capacity of 1K x 18 bits, totaling 18K bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum data rate of 66.7 MHz with a 10 ns access time. The component is housed in a 64-TQFP package (14x14 mm) and supports programmable flags for status monitoring. It is designed for unidirectional data transfer applications.

Feature Summary

• Synchronous operation ensures reliable data handling at specified clock rates
• Programmable flag support allows for customizable status indication
• Unidirectional bus direction simplifies interface design for specific data flows

Applications

• High-speed data buffering in communication systems
• Interface bridging between asynchronous logic blocks
• Data storage in digital signal processing pipelines

Procurement Notes

This component is officially discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary markets. Confirm RoHS compliance status as indicated in official documentation, noting potential regulatory restrictions. Ensure the source provides valid traceability for obsolete parts.

Selection Notes

Select this part only if legacy compatibility with the 72225 series is required. Consider the 64-TQFP package constraints and 10 ns speed requirements. Evaluate alternative active components if new designs are permitted, as end-of-life status limits long-term supply assurance.

Part Context

Part of the Renesas 7200 series synchronous FIFO family. This specific model represents an older generation of high-speed memory buffers. It shares architectural similarities with other 18-bit wide FIFOs in the lineup but is distinguished by its specific speed grade and pinout configuration.

Replacement Considerations

Official substitutes are not listed due to discontinuation. Cross-reference with IDT72225LB15PFI for functional equivalence. Verify pin compatibility and electrical specifications before considering any third-party alternatives.
