Description
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 base board 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.
