C.1.3 Reset Generator
The RCM5400W uses a reset generator to reset the Rabbit 5000 microprocessor when the
voltage drops below the voltage necessary for reliable operation. The reset occurs between
2.85 V and 3.00 V, typically 2.93 V.
The RCM5400W has a reset output, pin 3 on header J1.
C.1.4 Onboard Power Supplies
The +3.3 V supplied to the RCM5400W via header J1 powers most of the onboard circuits.
In addition, there is a +1.8 V DC linear regulator that provides the core voltage to the Rabbit
5000 microprocessor. Other linear regulators supply the additional voltage levels needed by
the Wi-Fi circuits.
