Memory IC Procurement Notes

Verify current lifecycle status directly with the manufacturer, as this specific part number has been identified as End-of-Life or obsolete in public records. Confirm availability of parameter-equivalent alternatives such as the W956D8NBRA5I series if production continuity is required. Check for any Product Change Notifications regarding material or design updates that may affect compatibility.

Memory IC Selection Notes

Select this component when a small form factor memory solution is needed for bandwidth-constrained interfaces. Ensure the host controller supports the HyperBus protocol and can operate within the specified 1.7V to 2V voltage window. Consider the 24-pin TFBGA footprint during PCB layout and verify thermal management capabilities for the intended operating environment.

Memory IC Part Context

This device belongs to the Winbond W956D8 family of HyperRAM products. These components are designed to replace traditional parallel SRAM in space-sensitive designs while offering higher density and lower pin counts. The family utilizes a serial interface to reduce board complexity and improve signal integrity compared to wide parallel buses.

Memory IC Replacement Considerations

Public records indicate the W956D8NBRA5I as a parameter-equivalent alternative. Verify electrical and mechanical compatibility before substitution.
