6.20 Non-Volatile Memory and Device Security
Features
The ZL2004 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 made available to them.
Refer to Section 5.3 “ Start-up Procedure ,” for details on
how the device loads stored values from internal
memory during start-up. During the initialization
process, the ZL2004 checks for stored values contained
in its internal non-volatile memory. The ZL2004 offers
two internal memory storage units that are accessible
by the user as follows:
1. Default Store : A power supply module
It should also be noted that the device’s V DD voltage
must be maintained during the time when the device is
writing the data to Flash memory; a process that
requires between 700-1400 μs depending on whether
the data is set up for a block write. Undesirable results
may be observed if the device’s V DD supply drops
below 3.0 V during this process.
Table 26. SNAPSHOT_CONTROL Command
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.

Copies current SNAPSHOT values from
Flash memory to RAM for immediate access
using SNAPSHOT command.
Writes current SNAPSHOT values to Flash
memory. Only available when device is
disabled.
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 AN33 for details on
how to set specific security measures via the
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
