Table B-1 lists the electrical, mechanical, and environmental specifications for the Proto-
typing Board.
B.2 Power Supply
The RCM3200 requires a regulated 3.3 V ± 0.15 V DC power source to operate. Depend-
ing on the amount of current required by the application, different regulators can be used
to supply this voltage.
The Prototyping Board has an onboard +5 V switching power regulator from which a
+3.3 V linear regulator draws its supply. Thus both +5 V and +3.3 V are available on the
Prototyping Board.
The Prototyping Board itself is protected against reverse polarity by a Shottky diode at D2
as shown in Figure B-2.
