8.3 Features
The flashdisk module works just like a disk drive and requires no drivers. It provides high-speed nonvolatile mass
storage in capacities of 8GB to 64GB. It is available in both MLC and SLC versions. The flashdisk plugs in to the
PCIe MiniCard / mSATA socket and is held in place with two spacers and screws (included). It operates over the
full -40ºC to +85ºC operating temperature range.
mSATA flashdisk features:
mSATA compatible interface
Sustained read performance of 30MB/s
Sustained write performance of 20MB/s
Implements dynamic wear-leveling algorithms to substantially increase longevity
BCH (6/12 bit) Error Detection Code/Error Correction Code (EDC/ECC0)
Intrinsic data integrity after power loss
Wear leveling algorithm provides more reliable data storage over time
Write protection setting by jumper for prevention of data overwrites
Supports boot function for Windows Embedded Standard 7, Windows Embedded CE, and Linux
Low power consumption, typical 110mA when active and 0.45mA in sleep mode
-40ºC to +85ºC operation
RoHS compliant
8.4 Installation
Installing an mSATA flashdisk module on Atlas is straightforward using the following steps.
1. Ensure power is disconnected from Atlas.
2. Remove the two screws from the standoffs located across from the PCIe MiniCard / mSATA
connector.
3. Align the flashdisk at a 45 degree upward slant with its edge finger edge aligned with the pins on the
connector, the memory chips on the top side, and the mounting holes align above the standoffs.
4. Slide the flashdisk into the connector and downward onto the standoffs.
5. Reinstall the two screws, securing the flashdisk module to Atlas.

POWER SUPPLY
Atlas requires only +5VDC input voltage as per the PC/104 Specification. It supports routing of +12VDC from the
input power connector to various other connectors. The +5V supply comes from an external source via the Power
Input connector. All the other on-board supply voltages are derived from the +5VDC main input.
A +5VDC/+12VDC source must be connected to the Atlas SBC power connector. An ATX power supply can be
used to power the Atlas SBC. The +5VDC/+12VDC power source is interfaced to the board on the locking
connector labeled Power Input. The +5VDC is used by the Atlas SBC for all its power subsystems. The +12VDC
is used for the LVDS panel backlight inverter.
10.
BATTERY BACKUP
Atlas includes a backup battery for CMOS RAM and real-time clock backup. The 3.0V lithium battery is mounted
on the board to provide the RTC voltage to the CMOS/RTC. The battery is a CR-2354/GUN or equivalent type
with 3 pins. The battery provides minimum 5 years lifetime based on Ta=25
battery is soldered on the top side of the board. The battery is an integrated unit with soldered terminals and
soldered on the top of the board. It is not a field replaceable battery. Connector BAT is provided to enable the
use of an external battery.
