72125L25SOG8

Overview

The Renesas Electronics Corporation 72125L25SOG8 is an asynchronous FIFO memory device featuring a 16K capacity organized as 1K x 16 bits. It supports unidirectional data transfer with a maximum clock frequency of 50MHz and an access time of 25ns. The component operates on a single 5.0V supply voltage and is housed in a 28-SOIC surface-mount package. This part is designed for high-speed parallel-to-serial conversion applications requiring reliable buffer management.

Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Unidirectional data flow architecture simplifies interface design
• High-speed performance supports up to 50MHz data rates
• Standard 28-SOIC packaging facilitates surface-mount integration

Applications

• Parallel-to-serial data conversion interfaces
• Clock domain crossing buffers in digital systems
• High-speed data buffering between disparate logic speeds
• Communication protocol interface buffering

Procurement Notes

Verify the exact suffix 'G8' against official Renesas documentation to confirm pinout and electrical specifications, as suffixes often denote specific package or environmental variants. Confirm current product status, as this component may be subject to discontinuation notices. Ensure compatibility with existing board layouts regarding the 28-SOIC footprint before procurement.

Selection Notes

Select this component when unidirectional asynchronous buffering is required at 50MHz speeds. The 1K x 16 organization suits applications needing moderate depth with wide data paths. Consider the 25ns access time relative to system timing requirements. Evaluate if bidirectional capability is unnecessary to justify the simpler unidirectional architecture.

Part Context

This part belongs to the Renesas 72125 series of asynchronous FIFOs. It shares architectural similarities with other members but differs in capacity and package type. The 72125L25SOG8 specifically targets applications requiring 16K depth in a compact SOIC form factor, distinguishing it from larger capacity or leaded-package variants within the same family.

Replacement Considerations

Check for direct substitutes such as IDT72125L25SO variants. Verify functional equivalence regarding access time, capacity, and unidirectional operation. Ensure pin compatibility with the 28-SOIC package before substitution.
