Safety instructions
nThe ConnectCore MP13 module cannot be guaranteed operation due to the radio link and so
should not be used for interlocks in safety critical devices such as machines or automotive
applications.
nThe ConnectCore MP13 module has not been approved for use in (this list is not exhaustive):
lnuclear applications
lexplosive or flammable atmospheres
nThere are no user serviceable components inside the ConnectCore MP13 module. Do not
modify the ConnectCore MP13 in any way. Modifications may exclude the module from any
warranty and can cause the ConnectCore MP13 to operate outside of regulatory compliance
for a given country, leading to the possible illegal operation of the radio.
nUse industry standard ESD protection when handling the ConnectCore MP13 module.
nTake care while handling to avoid electrical damage to the PCB and components.
nDo not expose ConnectCore MP13 module to water or moisture.
nUse this product with the antennas specified in the ConnectCore MP13 module user guides.

Power interfaces
System-on-module power architecture
The ConnectCore MP13 requires two primary power supply inputs: VSYS and VSYS2, which are the
input power supplies to the on-module ST STPMIC1 power management IC (PMIC) that generates all
required supply voltages for the module as well as the external interfaces.
The following table summarizes the PMIC regulators and switches on the ConnectCore MP13 SOM:

DDR_REF - VSYS2 YES NO
BOOST - VSYS YES NO
* This regulator is not available in initial versions of the module.
In addition to the input power supplies of the PMIC, other power domains of the SOM must also be set
externally. This allows power management flexibility so you can adapt the input voltage of the
different interfaces. The following table lists the input power rails that must be powered externally to
the SOM together with the devices/power domains they power:

Note Some of the electrical characteristics may depend on the configuration and operation mode of the different regulators. For a complete description
of the electrical characteristics of the different output power rails (PMIC regulators), see the STPMIC1 datasheet.
1The maximum output current involves both external and internal circuitry. For those regulators that are used internally in the SOM, the current
available outside will be lower.

The ConnectCore MP13 module has one antenna port on the module via a dedicated U.FL connector.
The antenna port supports WLAN and Bluetooth functionality.

The ConnectCore MP13 module supports both Bluetooth and Bluetooth Low Energy protocols:
nBluetooth 5 with all Bluetooth 4.2 optional features. Bluetooth class 1 and class 2 transmitter
operation.
nIntegrated WLAN-Bluetooth coexistence.

Module pinout External signals and pin multiplexing
ConnectCore MP13 System-on-Module 18
Module pinout
The ConnectCore MP13 module has a mixed pad structure. The module provides 245 LGA pins, 76 of
them connected to the peripheral castellated pads. The general layout can be found on the following
diagram:
White cells: LGA pads
Orange cells: castellated pads
Note Pad A1 is unconnected. This pad is meant for module-orientation purposes; its shape is square,
whereas all other pads are circular. Pad A1 should not be soldered down to a corresponding pad on
the carrier board.
External signals and pin multiplexing
The following tables provide the pinout information of the ConnectCore MP13 module. For additional
information related to the signals listed in the table, refer to the STMicroelectronics STM32MP1
technical documentation.

Module pinout External signals and pin multiplexing
ConnectCore MP13 System-on-Module 19
Note The Digi ConnectCore Smart IOmux tool can dramatically simplify pin configuration and
resolution. You can enter the list of interfaces required by your project and use the Smart IOmux
graphical interface to mock up configuration options, resulting in full pin assignment and device tree
snippets that match your desired functionality. See the Smart IOmux User Guide for more information
and download instructions.
The microprocessor used on this module, like all CMOS devices, can be driven into a latch-
up condition if any I/O pin is driven outside of its associated power rail. Care must be taken
to:
nNever drive an I/O pin beyond its positive rail or below ground.
nNever drive an I/O pin from an external power source during the power-on or reset
sequences.
nNever hot-swap the module or interrupt its ground connection to external circuitry.
Latch-up is a condition that can cause excessive current draw and result in excessive
heating of the microprocessor or its power supplies. This excessive heating can
permanently damage the microprocessor and/or its supporting components.
When you use an external supply on the carrier board supporting the ConnectCore MP13
module, make sure this supply is NOT back driving STM32MP1 I/Os while their power rails
are not enabled. For example, this can happen when an external 3.3V supply is available on
the carrier board and this supply powers components driven by STM32MP1 I/Os. In this
case, Digi recommends you enable the external power supply after internal 3.3V is enabled,
or add the necessary protection circuitry to avoid back voltage (leakage).
