4.2.2 Functional Description
The devices has three separated power domains and needs two different levels of power supplies. The core power
domain is supplied by VDDC and the analog power domain by AVDD. Both needs the same voltage level. The third
supply domain is supplied by VDDIO and powers GPIOs. See also 2.2 Recommended Operating Conditions.
4.2.3 Power Up Sequence Considerations
During power-up the power-on-reset configures all pads as inputs consequently disabling the output drivers. The
IO supply is watched after power up if the core supply is in the specified range and causes a reset if it leaves the
allowed region. The core supply is watched via a brown out circuit.
The pads will remain input pads as long as the software does not reconfigure them.
According the following diagram it must be guaranteed that ADVV / DVVC is not switched on before VDDIO. NRST
can be switched on if the VDDIO and AVDD/DVVC are stabilized on its potential.
A >= 0ms
B > 5ms (recommended)
To avoid floating gates, A < 100µs is recommended.
