ZL6105
In the event that the device experiences a fault and power is lost, the
user can extract the last SNAPSHOT parameters stored during the
fault by writing a 1 to SNAPSHOT_CONTROL (transfers data from
Flash memory to RAM) and then issuing a SNAPSHOT command
(reads data from RAM via SMBus).
Non-Volatile Memory and Device Security
Features
The ZL6105 has internal non-volatile memory where user
configurations are stored. Integrated security measures ensure
that the user can only restore the device to a level that has been
internal memory during start-up.
During the initialization process, the ZL6105 checks for stored
values contained in its internal non-volatile memory. The ZL6105
offers two internal memory storage units that are accessible by
the user as follows:
1. Default Store: A power supply module manufacturer may
want to protect the module from damage by preventing the
user from being able to modify certain values that are related
to the physical construction of the module. In this case, the
module manufacturer would use the Default Store and would
allow the user to restore the device to its default setting but
would restrict the user from restoring the device to the factory
settings.
2. User Store: The manufacturer of a piece of equipment may
want to provide the ability to modify certain power supply
settings while still protecting the equipment from modifying
values that can lead to a system level fault. The equipment
manufacturer would use the User Store to achieve this goal.
Please refer to Application Note AN2033 for details on how to set
specific security measures via the I 2 C/SMBus interface.
