• The internal eMMC flash storage has a limited number of write cycles. Therefore, it is
recommended that the amount of writing to flash is limited within software applications.

Always consider personal safety when installing and operating the product. For example,
in vehicle installations, CrossControl does not recommend that the product is being
actively operated by the driver when a risk of injury to people or damage to property is
present.
4.5.1. Cleaning
To ensure proper and reliable functionality over time, pay attention to the following cleaning
instructions and precautions:
•
Wipe the device clean from dirt using a soft damp cloth, preferably of microfiber type.
Larger amount of dry dust may be swept off using a soft brush before wiping clean.
• Avoid using alkaline, alcoholic or other potentially adverse chemicals for cleaning as doing
so may damage the device. However, small amount isopropyl alcohol may be used for
removing harsh stains.
• Avoid spraying or by other means applying larger amount of water or alcohol directly to the
device. Instead, lightly dampen a cloth before using it for cleaning the device.
•
After cleaning, make sure that the device surface is left dry.
•
Never use high-pressure air, vacuum, water or steam to clean the device.
4.5.2. Real time clock battery
Time and date information is stored in a memory sustained by an internal back-up battery. The
battery is a 3V 1000mAh high operating temperature Poly-carbonmonofluoride Lithium battery.
The expected lifetime of the battery is approximately 20 years. The battery is not replaceable.
4.6. Transportation
When transporting the device, it is recommended to use the original packaging. Make sure that
protective caps are used on all non-mated connectors. The safe storage temperature range [-
40°C to +80°C] must be adhered to.

The eMMC is used in pseudo SLC mode and implements both static and dynamic wear levelling to achieve the
best reliability. The number of program/erase cycles is between 20k to 60k depending on the manufacturer and
temperature. Our recommendation for the application software is to temporary cache in RAM and to write larger
chunks of data to the eMMC. This recommendation is not specific to eMMC but is applicable to all flash
memories.
