ConnectCore 6 SBC interfaces DC-in connector
Overvoltage protection
An overvoltage protection circuit is implemented on the ConnectCore 6 SBC. If the voltage value of the
DC-In supply signal is higher than 5.5V the supply input is disconnected of the system.
CAUTION! The maximum input voltage of the ConnectCore 6 SBC should never exceed the 12
VDC. Voltages over this limit may cause permanent damage to the board.
5V load switch
The ConnectCore 6 SBC has several interfaces that have to be powered from a 5V supply. This supply
comes from a Load switch, whose input comes directly from the DC Power Jack showed above. The
SIP32401A is a slew rate controlled load switch designed for 1.1V to 5.5V operation. The SIP32401A
features a low voltage control logic interface which is commanded by the PWR_EN signal (PMIC_
GPIO7). On low power mode this load switch will be disabled. The following table lists the interfaces of
the ConnectCore 6 SBC that are sourced from the Load switch.

ConnectCore 6 SBC interfaces SBC coin cell connector
SBC coin cell connector
The ConnectCore 6 SBC provides a 2-pin, 1.25mm pitch straight connector for connecting an external
coin cell or super capacitor to power the RTC interface when the main supply is off. If higher voltage is
present on the main supply, it will be used as a power source for the RTC.
The following table shows the pinout of the coin cell connector.
Pin Signal Comments
1 VCC_LICELL Power supply for RTC
2 GND Ground
There are three types of components that can be connected to this connector: lithium coin cells
(primary cell: non-rechargeable), lithium coin cells (secondary cell: rechargeable), and supercaps.
CAUTION! When a primary lithium coin cell is connected, the PMIC backup battery charger
must be turned off and this pin is used strictly as an input. It is hazardous to attempt to
charge primary lithium cells as they may vent or explode.
Secondary lithium coin cells are only made available directly to manufacturers of equipment that could
use them. Manufacturers are normally required to design products to prevent users from gaining
access to this part. This is because there is a danger to the user if by replacing it, they fit a primary
type (the only sort that they are likely to be able to source) into the charging circuit. When a secondary
lithium coin cell is used, both the charging current and the termination voltage are programmable.
When a supercap is used, both the charge current and termination voltage should be set to the
maximum values.
ConnectCore® for i.MX6 SBC Hardware Reference Manual
15
ConnectCore 6 SBC interfaces SBC boot configuration
The advantage of using a primary lithium coin cell is that the energy density usually allows years of
service since the self- discharge rate is low. The advantage of using a secondary lithium coin cell is
that the self-discharge rate is usually sufficient to allow a few months of support for the RTC before it
must be recharged. The advantage of the supercap is that it is intrinsically safe and can out-last the
primary lithium coin cell option. However, the self discharge rate is high, meaning that a 1F capacitor
at 25° C is likely to support the RTC for approximately five to ten days.
A programmable constant charge current charger with a programmable top-off charging voltage is
provided for charging of secondary lithium-manganese coin cell batteries and super capacitors.
Charging current is programmable from 100uA to 6mA. Termination voltage is programmable from
+1.1 to +3.1V.
The minimum voltage of the coin cell supply is +2V. The maximum voltage of the coin cell supply is
+3.6V.

ConnectCore 6 SBC interfaces XBee
XBee
The ConnecCore 6 SBC provides two 10-pin, 2mm pitch connectors to connect a Digi XBee/XBee Pro
module. The XBee identification and association signals are connected to a 3-pin, 1.25mm pitch
expansion connector.
The UART5 port of the ConnectCore 6 module is used to communicate with the XBee module. This
UART port is also connected to the UART expansion connector. Only one of the two UART5 interfaces
(XBee or Expansion) can be used at a time.
USB Host port 4 coming from the on-board USB Hub is connected to the XBee module socket. This
port allows to support USB capable XBee modules. USB Host port 4 is shared between XBee socket
and dedicated USB extension header (J32). Only one of the two location can be used at a time.
Three GPIO signals of the ConnectCore 6 module are used to reset the XBee, and control the status of
the XBee module.

CAUTION! The XBee socket is powered through an external DC/DC regulator(U23 - MP2316).
The purpose of this external regulator is to provide higher current than using 3V3 supply
coming from the ConnectCore 6 module. Disabling this regulator doesn't guarantee that
the XBee socket is fully disconnected from the module. In fact, some current travels
through the I/Os to the module even after the regulator is disabled.
If your design requires fully disconnecting the XBee socket from the ConnectCore 6 module,
Digi recommends you use bus switches for all I/Os connected to the XBee socket.
CAUTION! Do not expose any XBee socket pins to 5V unless it is specifically allowed by the
XBee model.

ConnectCore 6 SBC interfaces Audio
Audio
The ConnectCore 6 SBC provides an audio interface with headphone, line-out, line-in, and microphone
signals. The NXP SGTL5000 audio codec is used on the SBC to generate all the audio signals.
The headphone audio signal is connected to a stereo audio jack. The signal GPIO2_0 of the i.MX6 is
connected to the audio jack for the headphone detector functionality. When a headphone is connected
to the audio jack, the line-out channel will be muted and the CODEC will route the audio output to the
headphone. If a headphone is not connected the audio CODEC will connect the audio output to the
line-out channel.
To improve the power consumption during low power modes, the ConnectCore 6 SBC provides a
circuit to switch off the power supply of the audio codec. This switch is controlled with the GPIO2_25
of the i.MX6 processor. When the GPIO2_25 is at high level the audio codec is powered. When the
GPIO2_25 is at low level the audio codec is not powered.
