2.4.1
Data and code protection is implemented through a Protection State Machine (PSM). The user can
configure an independently programmable area of the flash memory as read protected, write
protected, or read/write protected.
A protected partition may be protected by either/both of these hardware mechanisms:
•
•
If the Lock option is enabled (by means of software) and the LOCK# signal is asserted, the
protected partition has an additional hardware lock that prevents read/write access to the partition,
even with the use of the correct protection key.
The size and protection attributes of the protected partition are defined during the media-formatting
stage.
In the event of an attempt to bypass the protection mechanism, illegally modify the protection key,
or in any way sabotage the configuration parameters, the entire mDOC H1 becomes both read and
write protected, and is completely inaccessible.
For further information on hardware protection, please refer to the TrueFFS Software Development
Kit (SDK) developer guide.
2.4.2
Each mDOC H1 is assigned a 16-byte UID number. Burned onto the flash during production, the
UID cannot be altered and is unique worldwide. The UID is essential in security-related
applications, and can be used to identify end-user products in order to fight fraudulent duplication
by imitators.
The UID on mDOC H1 eliminates the need for an additional on-board ID device, such as a
dedicated EEPROM.
2.4.3
The 6KB OTP area is user programmable for complete customization. The user can write to this
area once, after which it is automatically and permanently locked. After it is locked, the OTP area
becomes read only, just like a ROM device.
Typically, the OTP area is used to store customer and product information such as: product ID,
software version, production data, customer ID and tracking information.
2.4.4
The boot partition can be locked automatically by hardware after the boot phase is completed and
the device is in Normal mode. This is done by setting the Sticky Lock (SLOCK) bit in the Output
Control register to 1. This has the same effect as asserting the LOCK# signal. Once set, SLOCK can
only be cleared by asserting the RSTIN# input. Like the LOCK# input, assertion of this bit prevents
the protection key from disabling the protection for a given partition. There is no need to mount the
partition before setting this bit.
