Please refer to the SAMA5D2 Series datasheet for more information. 3.2.2 Power Supply Topology and Power Distribution 3.2.2.1 Input Power Options Two options are available to power the SAMA5D2-PTC-EK board. The USB-powered operation is the default configuration and comes from the USB device ports (J4-J9) connected to a PC or a 5VDC supply. Such USB power source is sufficient to supply the board in most applications. It is important to note that when the USB-powered operation is used, the USB port down the way has a limited powering capability. If the USB-B Host port (J3) is required to provide full powering capabilities to the target application, it is recommended to use an external DC supply instead of a USB power source. The following figure is a schematic of the power options. SAMA5D2-PTC-EK Board Components © 2017 Microchip Technology Inc. DS50002709A-page 9 |
