MYD-JA5D27 Development Board

The MYD-JA5D2X Development Board is a complete evaluation platform for Atmel’s SAMA5D2 (26/27) ARM Cortex-A5 processor which supports multiple memories, including latest-generation technologies such as DDR3, LPDDR3, and QSPI Flashand is integrated with rich peripherals including the LCD & Touch controller, Camera interface, EMAC, USB HSIC and Safety IP, capable of running at up to 500MHz. The MYD-JA5D2X development boards is consist of a CPU module MYC-JA5D2X and a base board MYB-JA5D2X connected via one 200-Pin SODIMM interface. It is designed to be a complete design reference for embedded developing on the SAMA5D2X processor and designs based on MYC-JA5D2X CPU Module.

MYD-JA5D2X Development Board

The MYC-JA5D2X CPU Module has integrated the core components including the SAMA5D2 processor, 256MB DDR3, 256MB Nand Flash, 4MB Data Flash, 64KB EEPROM and 100M Ethernet PHY on board. It has been designed to support up to 512MB DDR3 and 1GB Nand Flash (or 16GB eMMC Flash) on customer demand. They can be embedded into your next design directly to speed up your time to market. A rich set of peripherals and interfaces have been brought out through headers and connectors to the MYD-JA5D2X base board including serial ports, USB Host and Device ports, one CAN port (only for SAMA5D27), one 10/100Mbps Ethernet port, RS485, TF card slot, Audio in/out, LCD, etc.

MYC-JA5D2X CPU Module

MYIR deliveries the MYD-JA5D2X Development Board with SAMA5D27 processor by default. The board comes along with Linux 4.1 software packages, necessary cable accessories as well as detailed documents to enable quick start when getting the goods out of box. It can support -40 to +85 Celsius extended temperature operation for industrial embedded applications. It is an excellent EVM (Evaluation Module) and a good reference design for extensively evaluation, fast prototyping and creating applications that require high efficient computing, display, audio, mass storage, networking, connectivity and more.
