RabbitCore RCM2200
The drain on the battery by the RCM2200 is typically 16 A when no other power is sup-
plied. If a 950 mAh battery is used, the battery can last more than 6 years:
The actual life in your application will depend on the current drawn by components not on
the RCM2200 and the storage capacity of the battery. Note that the shelf life of a lithium ion
battery is ultimately 10 years. The RCM2200 does not drain the battery while it is powered
up normally.
The battery-backup circuit serves three purposes:
It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting
the current consumed by the real-time clock and lengthening the battery life.
It ensures that current can flow only out of the battery to prevent charging the battery.
A voltage, VOSC, is supplied to U6, which keeps the 32.768 kHz oscillator working
when the voltage begins to drop.
VRAM and Vcc are nearly equal (<100 mV, typically 10 mV) when power is supplied to
the RCM2200.
Figure C-2 shows the RCM2200 battery-backup circuit.

C.1.2 Reset Generator
The RCM2200 uses a reset generator, U1, to reset the Rabbit 2000 microprocessor when the
voltage drops below the voltage necessary for reliable operation. The reset occurs between
4.50 V and 4.75 V, typically 4.63 V. The RCM2200 has a reset output, pin 9 on header J5.
