10.8. Power Supply Design

The power supply requirements for Intel® Arria® 10 devices vary depending on the static and dynamic power for each specific use case. To reduce dynamic power of the Intel® Arria® 10 device to a negligible amount before power down, hold the nCONFIG pin low to force the Intel® Arria® 10 device into a reset state. Intel® ’s Enpirion® portfolio of power management solutions, combined with comprehensive design tools, enable optimized Intel® Arria® 10 device power supply design. The Enpirion portfolio includes power management solutions that are compatible with the multiple interface methods utilized by the Intel® Arria® 10 device and designed to support Intel® Arria® 10 power reduction features such as the SmartVID feature.

Intel® Arria® 10 devices have multiple input voltage rails that require a regulated power supply in order to operate. Multiple input rail requirements may be grouped according to system considerations such as voltage requirements, noise sensitivity, and sequencing. The Intel Arria 10 GX, GT, and SX Device Family Pin Connection Guidelines provides a more detailed recommendation about which input rails may be grouped. The Power Analyzer for Intel® Arria® 10 devices also seamlessly and automatically provides input rail power requirements and specific device recommendations based on each specific Intel® Arria® 10 use case. Individual input rail voltage and current requirements are summarized on the “Report” tab while input rail groupings and specific power supply recommendations can be found on the “Main” and “Enpirion” tabs, respectively.
