Atmel SAME70-XPLD User Manual

4. Hardware User Guide
4.1. 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.

4.2. Power Distribution
The SAME70-XPLD has two power sources as described in the figure Power Supply Block Diagram.
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.
