The SAMA5D3 Xplained board is built around the integration of a Cortex ®-A5-based microcontroller (BGA 324 package)
with external memory, dual Ethernet physical layer transceiver, two SD/MMC interfaces, two host USB ports and one device USB port, one 24-bit RGB LCD interface and one debug interface.
Eight headers, compatible with Arduino R3, are available for various shield connections.
Figure 1-1 SAMA5D3 Xplained
The SAMA5D3 Xplained board is built around the SAMA5D36, a Cortex-A5 application processor which combines high-performance computing device with low-power consumption and a wide range of communication peripherals. It features a combination of user interface functionalities and high data rate IOs, including LCD controller, touchscreen, camera interface, Gigabit and 10/100 Ethernet ports, high-speed USB and SDIO.
The ARM Cortex-A5 supports the latest generation of DDR2 and NAND Flash memory interfaces for program and data storage. An internal 166-MHz multi-layer bus architecture associated with 24 DMA channels and two 64-Kbyte SRAM blocks, sustains the high bandwidth required by the processor and the high-speed peripherals.
