Microcontroller
The SAME70-XPLD board is built around the ATSAME70Q21 in a 144-lead LQFP package. It is a low-
power ARM Cortex-M7 application microcontroller achieving high-performance computing device and
embedding a wide range of communication peripherals. It features a combination of user interface
functionalities and high data rate IOs, camera interface, 10/100 Ethernet ports, high-speed USB and SD
Card.
The ARM Cortex-M7 processor supports SDRAM memory through an EBI interface. An internal 150 MHz
multi-layer AHB bus architecture associated with 24 XDMA channels, 384 Kbytes of SRAM and 2048
Kbytes of Flash sustains the high bandwidth required by the microcontroller and the high-speed
peripherals.

Power Distribution
The SAME70-XPLD has two power sources as described in the figure
The kit can be powered from the EDBG USB or from the target USB. The kit automatically selects a
source to draw power. Priority is given to TARGET USB power input.
