Note that some of the specications refer to either the “EFR32MG13” chip or the “Module”. Specications cited as EFR32 are
taken from the EFR32MG13 datasheet (this should also be noted where referred to). Module means measurements taken
with our production module.
In order to access the EFR32 for programming and debug purposes, it is recommended that the designer incorporate
Silcon Labs 10-pin Mini Simplicity connector.
The following table shows a pin mapping between Silicon Labs 10-pin Mini Simplicity connector and the module, and the

The CSB04PA1x family of devices use a System on Module (SOM) package process technology.
The diagram below shows the recommended dimensions and arrangement of the pads for the module. The PCB upon
which the module will be mounted should not include any non-ground traces or vias on the top layer directly under the
module. All copper features other than the module mounting pads, including ground vias, should be tented or covered
with soldermask to avoid coming in contact with the module’s traces and producing unexpected behavior. If it is absolutely
necessary to include traces and/or vias under the module due to space constraints, then a customer can elect to do so at
their own risk. MMB can provide a Hardware Designer Package to show the module’s footprint and drill locations, which
must not line up with the daughtercard’s drill locations.
Note: Green box is the size of the top metal layer. Orange is the opening in the soldermask layer.

of your PCB and re-ow.
9 | Regulatory Approvals
9.1 | Federal Communications Commission (FCC - US)
Note: this section applies to CSB04PA10-CHP and CSB04PA10-RFC devices only.
9.1.1 | Approved Antennae
For the CSB04PA10-CHP modules using the onboard chip antenna, the approved 802.15.4 power level settings are
19.2 dBm for channels 11-25 and 15 dBm for channel 26. The approved BLE power level settings are 19.2dBm for both
connected and advertising modes. The onboard chip antenna is Inpaq ACA-2012-A1-CC-S with a gain of 1.72dBi and
50Ω impedance.
For the CSB04PA10-RFC modules using the approved external antenna, the approved 802.15.4 power level settings
are 19.2 dBm for channels 11-25 and 8 dBm for channel 26. The approved BLE power level settings are 19.2dBm
for connected mode and 15dBm for advertising modes. The CSB04PA1x-RFC devices have been approved with the
following external FCC approved antennas: Mag Layers EDA-1713-2G4C1-A2, and Bondale G-RA0K13200284-SZ478
with a gain of 5dBi and nominal impedance of 50Ω.
9.1.2 | FCC Notice
The CSB04PA1x-CHP and CSB04PA1x-RFC devices comply with Part 15 of the FCC rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause undesired operation.
To comply with FCC RF Exposure requirements, users of this device must ensure that the module be installed and/or
congured to operate with a separation distance of 20cm or more from all persons.
Usage of Channel 26 at full power will result in non-compliance to FCC standards. MMB recommends avoiding use of
channel 26 and if necessary only use with a reduced power setting. For further details please contact MMB.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of
Preliminary Information
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment o and on, the user is encouraged to try
to correct the interference by one of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to whichthe receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
9.1.3 | Modular Approval
The CSB04PA1x-CHP and CSB04PA1x-RFC devices meet the requirements for modular transmitter approval as detailed in
the FCC public notice DA 00-1407.
It should be noted that:
“While the applicant for a device into which an authorized module is installed is not required to obtain a new authorization
for the module, this does not preclude the possibility that some other form of authorization or testing may be required for
the device (e.g., a WLAN into which an authorized module is installed must still be authorized as a PC peripheral, subject to
the appropriate equipment authorization).”
-- FCC Public Notice DA 00-1407
Caution:
Changes or modications not expressly approved by the party responsible for compliance could void the user’s authority
to operate the equipment.
NOTE:
This module is intended for an OEM integrator. The OEM integrator is responsible for the compliance to all the rules that
apply to the product into which this certied RF module is integrated. Additional testing and certication may be necessary
when multiple modules are used.
A 20cm minimum distance has to be able to be maintained between the antenna and the users for the host this
module is integrated into. Under such conguration, the FCC radiation exposure limits set forth for a population/
uncontrolled environment can be satised. Further RF exposure shall be re-evaluated to the scenario of portable, and
collocated use.
USER MANUAL OF THE END PRODUCT:
In the user manual of the end product, the end user has to be informed to keep at least 20cm separation with the antenna
while this end product is installed and operated. The end user has to be informed that the FCC radio-frequency exposure
guidelines for an uncontrolled environment can be satised.
The end user has to also be informed that any changes or modications not expressly approved by the manufacturer could
void the user’s authority to operate this equipment.
The user of this device is responsible for meeting the FCC labeling requirements. A clearly visible label on the exterior
enclosure of an incorporating device must list the MMB Research Inc. FCC ID “XFF-CSB04PA1X” and the FCC Notice above
(section 9.1.1).
The exterior label should use the wording “Contains” or “Contains Transmitter Module”. For example:
Contains FCC ID: XFF-CSB04PA1X
or
Contains Transmitter Module FCC ID: XFF-CSB04PA1X
Any similar wording that expresses the same meaning may be used. If the labelling area is smaller than the palm
of the hand, then additional FCC part 15.19 statement is required to be available in the users manual: This device
complies with Part 15 of FCC rules. Operation is subject to the following two conditions: (1) this device may not cause
harmful interference and (2) this device must accept any interference received, including interference that may cause
undesired operation.
LABEL OF THE END PRODUCT:
The nal end product must be labeled in a visible area with the following “Contains TX FCC ID: XFF-CSB04PA1X”.
If the labelling area is larger than the palm of the hand, then the following FCC part 15.19 statement has to also be
available on the label: This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and (2) this device must accept any interference received, including
interference that may cause undesired operation.
