Specialty Logic Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that the product is discontinued and no longer available for new procurement. Verification of current availability should be conducted directly with authorized distributors or via official discontinuation notices, as standard inventory sources do not stock this item.

Specialty Logic Selection Notes

Selection requires compatibility with SSTL_2 signaling standards and specific voltage ranges between 2.3V and 2.7V. The device is intended for registered buffers in DDR memory environments. Designers must account for the 56-pin VFQFPN package constraints and ensure thermal management aligns with the specified operating temperature range of 0°C to 70°C.

Specialty Logic Part Context

The SSTVA16859CKLF belongs to the SSTVA16859C series of logic ICs within the Renesas portfolio. It serves as a specialized registered buffer for high-speed memory interfaces. The part is categorized under Logic ICs and is functionally related to other variants such as the SSTVA16859AG, differing primarily in packaging and specific pinout configurations.

Specialty Logic Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative sourcing requires consulting official cross-reference lists or engineering change notifications from Renesas Electronics.
