Processor

The SAMA5D2 Series is a high-performance, power-efficient embedded MPU based on the ARM

®

Cortex

®

-A5 processor.

Please refer to the SAMA5D2 Series datasheet for more information.

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.
