Arria® 10 FPGAs and Stratix® 10 FPGAs part numbers with the Power Option set to L are low-power devices. In the EMIF Spec Estimator tool, no results are shown if 2L or 3L is selected in the Temperature & Speed Grade tab.
Low-power Arria® 10 FPGAs and Stratix® 10 FPGAs have the same EMIF frequency specification as the standard power devices. In the EMIF Spec Estimator tool, select a Speed Grade of 2 and 3 to find the maximum frequency of the supported configurations for low-power Arria® 10 FPGA and Stratix® 10 FPGA devices.
