2.85 V and 3.00 V, typically 2.93 V. Since the RCM4510W will operate at voltages as low as
3.0 V, exercise care when operating close to the 3.0 V minimum voltage (for example, keep
the power supply as close as possible to the RCM4510W) since your RCM4510W could
reset unintentionally.
The RCM4510W has a reset output, pin 3 on header J1.
C.1.4 XBee RF Module Power Supply
The XBee RF module is isolated from digital noise generated by other components by way
of a low-pass filter composed of L5 and C90 on the RCM4510W as shown in Figure C-3.
The filtered power supply powers the XBee RF module, and is available via pin 8 of auxil-
iary I/O header J4 on the RCM4510W module. If you draw on this filtered power supply, the
maximum current draw is 25 mA.

C.2 Powerdown Mode
The XBee RF module can power down the remaining RCM4510W circuitry via the
or the
Dynamic C function calls. The real-time

clock and the data SRAM will still be powered during the powerdown from the +3.3 V
DC supplied to the RCM4510W module via header J1 as long as that voltage exceeds the
voltage of the backup battery.
