Power-up Sequence
Maximum Rise Rate
Minimum Rise Rate
To avoid risk of latch-up, the rise rate of the power supplies must not exceed the values
described in
Recommended order for power supplies is also described in this table.
The integrated Power-Reset circuitry monitoring the VDDIN powering supply requires a mini-
mum rise rate for the VDDIN power supply.
See
If the application can not ensure that the minimum rise rate condition for the VDDIN power sup-
ply is met, one of the following configuration can be used:
• A logic “0” value is applied during power-up on pin PA11 until VDDIN rises above 1.2V.
• A logic “0” value is applied during power-up on pin RESET_N until VDDIN rises above 1.2V.
