RabbitCore RCM3700
A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mA·h is
recommended. A lithium battery is strongly recommended because of its nearly constant
nominal voltage over most of its life.
The drain on the battery by the RCM3600 is typically 6 µA when no other power is sup-
plied. If a 235 mA·h battery is used, the battery can last about 4.5 years:
Note that the shelf life of a lithium ion battery is ultimately 10 years. The RCM3600 does
not drain the battery while it is powered up normally.
D.1.2 Reset Generator
The RCM3600 uses a reset generator to reset the Rabbit 3000 microprocessor when the
voltage drops below the voltage necessary for reliable operation. The reset occurs between
2.55 V and 2.70 V, typically 2.63 V.
The RCM3600 has a reset pin, pin 36 on header J1. This pin provides access to the reset
output from the reset generator, and is also connected to the reset input of the Rabbit 3000
to allow you to reset the microprocessor externally. A resistor divider consisting of R21
and R22 attenuates the signal associated with an externally applied reset to prevent it from
affecting the reset generator.
