The MYC-JA5D2X CPU Module is a core controller board powered by Atmel SAMA5D2 which is a high-performance, ultra-low-power ARM Cortex-A5 processor-based MPU and runs up to 500MHz, supporting multiple memories, including the latest generation such as DDR3, LPDDR3, and QSPI Flash. It is an embedded processing card with integrated 256MB DDR3 SDRAM, 256MB Nand Flash, 4MB Data Flash, 64KB EEPROM and Ethernet PHY and can be easily embedded into your next design. With the SO-DIMM I/O expansion connector, a number of I/O signals are available to enable your baseboard extension and implement more functions and flexible configurations based on customer demand.

The Atmel SAMA5D26 and SAMA5D27 processors are compatible to be used on the MYC-JA5D2X CPU Module. MYIR delivers the module with 5D27 device by default. The module is capable of running Linux 4.1 and can work in industrial temperature ranging from -40 to +85 Celsius.

MYIR offers a development board MYD-JA5D2X built around the MYC-JA5D2X CPU Module and has extended various peripherals through headers and connectors on the baseboard 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. It is a good reference design for development based on Atmel SAMA5D2 MPUs.

MYIR also provides custom design services, we can help with your baseboard design based on the MYC-JA5D2X CPU module rapidly; we can also modify on existing hardware, whether reducing, adding or removing functions according to your requirements.
