DDR unit is used as system cache, using domestic autonomous DDR3 SDRAM chip, with domestic CPU cooperation, improves the peace of product Quan Xing；

Memory element adopts domestic autonomous embedded eSSD chip 157TFBGA-16X20_0, and this chip is used for storing system The startup file of system, file system and other users data.

It is connected by SATA bus between CPU and eSSD, bus arranges a SATA signal shift switch, implied termss Under, system, using the eSSD hard disk carrying on computer module, also can take into account the need for SATA bus in different application simultaneously Ask.

NE realizes the network connection between CPU and mainboard, and interface unit is used as between computer module and mainboard Signal connect, power subsystem provides the power supply of whole computer module, and the main power supply chip adopting is Linear's LTM4622.

The one or more technical schemes providing in the embodiment of the present application, at least have the following technical effect that or advantage：

ESSD technology application in the design of Embedded Computer On Modules, be instead of tradition application by the present utility model The somewhat complex design mode of middle NAND Flash+ hard disk, effectively improves system start-up speed, reduces small product size, simplifies Production technology, improves product reliability.

The exploitation of domestic eSSD chip simultaneously comes into commercial stage, and the technical specification of product disclosure satisfy that military project, boat The application demand in the fields such as sky, meet these fields for production domesticization memory device requirement.

The application mainly utilizes the advantage that eSSD package dimension is little, capacity is big, by necessary for embedded board work system System startup file, file system and other users data storage are in eSSD chip internal.The transmission speed of chip 6Gbps can be protected The stable transmission of card data efficient, the chip capacity of more than 16GB can meet the data storage requirement of various application scenarios.
