Rev. 1.0.1
By clicking on the Flash button, user will start
programming
sequence
of
the
design
configuration into the Flash NVM. After the
programming sequence completes, the chip
will reset (if automatically reset After Flashing
box is checked), and boot the design
configuration from the Flash.
For users that wish to create their own
programming procedure so they can re-
program Flash in-circuit using their system
software, please contact Exar for a list of I2C
Flash Commands needed.
During a design process a user might want to
repeatedly download a design configuration
onto run time registers without saving it in
Flash. This is done through PA5 as well.
ENABLING XRP7724
XRP7724 has a weak internal pull-up ensuring
it gets enabled as soon as internal voltage
supplies
have
ramped up
and
are
in
regulation.
Driving the Enable pin low externally will keep
the controller in the shut-down mode. A
simple
open
drain
pull
down
is
the
recommended way to shut XRP7724 down.
If the Enable pin is driven high externally to
control XRP7724 coming out of the shut-down
mode, care must be taken in such a scenario
to ensure the Enable pin is driven high after
Vcc gets supplied to the controller.
In the configuration when Vcc = LDO5 =
4.75V to 5.5V, disabling the device by
grounding
the
Enable
pin
is
not
recommended. At this time we recommend
leaving the Enable pin floating and placing the
controller in the “Standby Mode” instead in
this scenario. The standby mode is defined as
the state when all switching channels and
LDO3.3 are disabled, all GPIO/PSIOs are
programmed as inputs, and system clock is
disabled. In this state chip consumes 440uA
typical.
