4 MEMORY

4.1 DDR2 512MB

Hynix DDR2 memory chips provides 512MB RAM which opens up a wide range of production and development opportunities. DDR2 memory consumes more power than MobileDDR. But, it is pretty much cost effective for huge memory space.

You can choose memory vendor for example Samsung/Hynix/Elpida/Micron or others due to PC industry standard. DDR2 8Bit-bus-width memory is being used for PC/Notebook memory module.

Each chip has 8-bit data-bus-width with 128MB. We mounted 4 chips to make 32bit data bus and total memory size is 512MB.

Full part number is H5PS1G83EFR-S6. @Hynix_DDR2.pdf (565.11 KB)

Very useful application note for engineers. @DDR2_device_operation&timing_diagram(Rev.0.1).pdf (847.7 KB)

4.2 2GB T-Flash(Micro-SD) Card

Traditional memory(Like NOR-FLASH / NAND-FLASH) can't be found in Odroid. Odroid has totally different booting method. Odroid implements direct T-Flash booting with excellent iROM feature of S5PC100.

Odroid has 2Gbyte T-flash(removable) memory card for system area. Assume it has 3,862,528 blocks(sectors) and each block has 512bytes.

4.3 8GB SDHC Card


At this moment, Google Android supports only FAT32 file system. Other file system can be considered for big size 720p-HD contents. 2GB/4GB/8GB seems to be working well. But, 16GB memory card has some compatibility issues.

4.4 Where is T-flash(Micro-SD)

Odroid has 2 memory cards.
  • T-flash card contains boot-loader, kernel, Android system and applications.
  • SD card contains user files such as pictures, music, video clips and so on.

Open the battery cover and you can find them.

8 Power Supply

8.1 PMIC


PMIC MAX8698C supplies important power rails of S5PC100 and other devices. It contains 3 Step-down DC/DCs and 9 LODs.


Recently we've got the permission of posting this datasheet from Maxim. But, the permission is limited to this home page. Do not distribute/spread this file to anywhere.

Special thanks: Maxim people.

8.2 DC/DC for Wireless device

Wifi-BT combo module consumes a lot of power and PMIC is not enough. So, Odroid takes additional high efficient DC/DC converter MAX1556 of Maxim.

10 Touch switch (Sound volume up/down)


Odroid volume switches are implemented with touch sensitive IC TS01 from AD-semiconductor.



11 JTAG


CAUTION: To connect JTAG emulator, you need to open the case and solder many wires.
This process can break touch screen flat cable. The touch screen flat cable is really weak.
Note that "This work should be done with your own risk. Any warranty will be completely gone away.
