MYD-JA5D27 Development Board | ATMEL SAMA5D27 ARM Cortex-A5 Controller Board-Welcome to MYIR

The MYD-JA5D2X Development Board is a complete evaluation platform for Atmel’s latest SAMA5D2 (26/27) ARM Cortex-A5 processor which supports multiple memories, including latest-generation technologies such as DDR3, LPDDR3, and QSPI Flash and 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 board is consist of a CPU module MYC-JA5D2X and a base board MYB-JA5D2X connected via one 200-Pin SODIMM interface. It is a complete design reference for embedded developing on the SAMA5D2X processor and designs based on MYC-JA5D2X CPU Module.

 

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.

MYC-JA5D2X CPU Module

The MYD-JA5D2X development board is built around the MYC-JA5D2X CPU Module and takes out full features of the

Atmel SAMA5D2 processor to extend a rich set of peripherals and interfaces through headers and connectors including serial ports, USB Host and Device ports, CAN port (only for SAMA5D27), Ethernet port, RS485, TF card slot, Audio in/out, LCD, etc.

MYD-JA5D2X Development Board

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.
