How should I handle unused SDM_IO pins in Stratix 10 devices?


You can leave unused SDM_IO pins open in Stratix® 10 devices, because  each SDM_IO  pin contains a 25kΩ internal pull-up or pull-down resistor as follows:

SDM_IO1/2/3/4/5/6/7/9/10/11/12/13/14/15 - 25kΩ internal pull-up resistor

SDM_IO0/8/16 - 25kΩ internal pull-down resistor


Intel® Stratix® 10 GX, MX, and SX Device Family Pin Connection Guidelines will be updated in a future release to include this guidance.
