Description
The MYD-SAM9X5 Development Board is designed by MYIR for the Atmel AT91SAM9X5 series ARM926EJ-S processors which can operate at up to 400MHz. It has a base board which can be equipped with five different CPU modules based respectively on Atmel’s SAM9G15, SAM9G25, SAM9G35, SAM9X25 and SAM9X35 embedded MPUs. All five CPU modules are sharing the same circuit design with minor configuration settings. They are compatible with Atmel's official SAM9X5-EK and can work on SAM9X5-EK'sbase board directly. The MYD-SAM9X5 is capable of running Linux and Android operating systems and also provided with complete sample codes bundle for the peripherals using Keil's MDK-ARM to enhance debugging capabilities for non-OS development. The 4.3- and 7-inch LCD panels are add-on options for the SAM9G15, SAM9G35 and SAM9X35 evaluation kit. It can work in harsh environment supporting -40 to +85°C extended temperature operation. MYIR also offers camera, WiFi, GPS and GPRS modules as add-on options which have greatly enhanced the functions of the development board.
The CPU module MYC-SAM9X5 has the most features of the processor and integrates 128MB DDR2 SDRAM, 256MB Nand Flash, 4MB Data Flash, 64KB EEPROM and Ethernet PHY on board. It is connected with the base board through a 1.8v DDR2 SD-DIMM 200-pin connector which provides an interface for the base board to carry all the I/O signals to and from the CPU module. A set of peripherals have been brought out through headers and connectors on the base board including serial ports, USB, Ethernet, CAN, LCD, Audio, SD, etc.
The MYD-SAM9x5 Development Board series have following models:
MYD-SAM9G15 development board (based on Atmel AT91SAM9G15) using MYC-SAM9G15 as CPU Module
MYD-SAM9G25 development board (based on Atmel AT91SAM9G25) using MYC-SAM9G25 as CPU Module
MYD-SAM9G35 development board (based on Atmel AT91SAM9G35) using MYC-SAM9G35 as CPU Module
MYD-SAM9X25 development board (based on Atmel AT91SAM9X25) using MYC-SAM9X25 as CPU Module
MYD-SAM9X35 development board (based on Atmel AT91SAM9X35) using MYC-SAM9X35 as CPU Module
From above table, we can see if you need Ethernet, except MYD-SAM9G15, other four models all can support; if you need two CANs, two Ethernet but no need LCD, the MYD-SAM9X25 is a good choice; if you want to evaluate the performance of this industrial board, the MYD-SAM9X35 has the most complete functions.
The MYD-SAM9X5 Development Board comes along with Linux 2.6.39 and android 2.3.5 software packages, MDK-ARM sample codes bundle, necessary cable accessories as well as detailed documents to allow customers to start development soon when getting the goods out of box. It is a low-cost full-featured development board for embedded and industrial applications.

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:
