Hardware Specification

The Atmel® SAM9G and SAM9X embedded MPUs are high-performance, highly integrated processors built the

good foundation of the Atmel® ARM926-based embedded MPU line. Running at 400 MHz, they are designed to

complement the power of the ARM926 core; these flexible devices deliver a rich combination of peripherals

including up to two Ethernet, two CAN, three USB ports and seven UARTS. Additional features include an

integrated soft modem, TFT LCD controller and LPDDR/DDR2 memory support. A multilayer bus matrix

architecture and multiple DMA channels ensure uninterrupted data transfer with minimum processor

intervention. Low voltage, low power consumption and reduced system cost make these devices ideal for

cost-sensitive machine-to-machine applications.

The MYD-SAM9X5 series development boards include one CPU module mounted on one base board. It takes full

features of the Atmel SAM9G and SAM9X processors and is characterized as in below table 1-2:
