Power supply

The STM3210E-EVAL Evaluation board is designed to be powered by a 5 V DC power
supply and to be protected by PolyZen (U15) in the event of a wrong power plug-in. It is
possible to configure the Evaluation board to use any of the following three sources for the
power supply:
• 5V DC power adapter connected to the power jack on the board (CN17 - PSU on silk
screen for power supply unit).
•
5V DC power with 500 mA limitation from the USB Type-B connector (CN14 - USB on
silkscreen).
•
5V DC power from the two extension headers for the daughterboard (CN10 and CN11 -
DTB for daughterboard on the silkscreen).
The power supply is configured by setting the related jumpers (JP13, JP12, and JP1) as
described in
powered correctly.

JP13 is used to select one of the three possible power supply
resources.
For the power supply jack (CN17) to the STM3210E-EVAL only, JP13
is set as shown (Default setting).
For the power supply from the daughterboard connectors (CN10 and
CN11) to STM3210E-EVAL only, JP13 is set as shown.
For the power supply from USB (CN14) to STM3210E-EVAL only, JP13 is
set as shown.
For the power supply from the power supply jack (CN17) to both
STM3210E-EVAL and daughterboard connected to CN10 and CN11,
JP13 is set as shown (The daughterboard must not have its power supply
connected).
Enables consumption measurements of both VDD and VDDA.
The default setting is ON
Vbat is connected to 3.3 V power when JP1 is set as shown
(Default setting).
Vbat is connected to the battery when JP1 is set as shown.
