10.8. Power Supply Design

The power supply requirements for Arria® 10 devices vary depending on the static and dynamic power for each specific use case. To reduce dynamic power of the Arria® 10 device to a negligible amount before power down, hold the nCONFIG pin low to force the Arria® 10 device into a reset state.

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 Arria® 10 devices also seamlessly and automatically provides input rail power requirements and specific device recommendations based on each specific Arria® 10 use case. Individual input rail voltage, current requirements, and input rail groupings are summarized on the “Report” tab.
