Additional Pin Functions
BGA Pin Assignment
Voltage Select
Enables the internal voltage regulator for 3.3 V-only operation
mode if connected to V
Disables the internal voltage regulator for dual power supply mode
if connected to V
Positive Power Supply
for the digital core (1.8 V)
These pins can either be positive power supply input or output
depending on the VSEL input condition.
If the VSEL pin is connected to V
must both be connected to the same 1.8 V power supply and
require decoupling.
If the VSEL pin is connected to V
1.8 V power supply outputs and must be decoupled to V
Attention: These pins must not be used to supply external
Positive Power Supply for the analog PLL (3.3 V)
Power Supply Ground for the analog PLL (0 V)
