The drain on the battery by the RCM3100 is typically 7.1 µA when no other power is sup-
plied. If a 165 mA·h battery is used, the battery can last almost 3 years:
The actual life in your application will depend on the current drawn by components not on
the RCM3100 and the storage capacity of the battery. The RCM3100 does not drain the
battery while it is powered up normally.
Cycle the main power off/on on the RCM3100 after you install a backup battery for the
first time, and whenever you replace the battery. This step will minimize the current drawn
by the real-time clock oscillator circuit from the backup battery should the RCM3100
experience a loss of main power.
D.1.2 Reset Generator
The RCM3100 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
2.55 V and 2.70 V, typically 2.63 V. The RCM3100 has a reset output, pin 1 on header J2.
