The drain on the battery by the RCM3200 is typically 12 µA when no other power is sup-
plied. If a 165 mA·h battery is used, the battery can last almost 2 years:
The actual life in your application will depend on the current drawn by components not on
the RCM3200 and the storage capacity of the battery. Note that the shelf life of a lithium ion
battery is ultimately 10 years. The RCM3200 does not drain the battery while it is powered
up normally.
D.1.2 Reset Generator
The RCM3200 uses a reset generator to reset the Rabbit 3000 microprocessor when the volt-
age drops below the voltage necessary for reliable operation. The reset occurs between
2.85 V and 3.00 V, typically 2.93 V. The RCM3200 has a reset output, pin 1 on header J2.
D.2 Optional +5 V Output
The RCM3200 boards have an onboard charge pump that provides the +5 V needed by the
RealTek Ethernet chip.
