KEY POINTS
ted customer applications and fast time to market.
• Available with integrated chip antenna or
an RF pin
The WGM160P module integrates all of the necessary elements required for a cloud
connected IoT Wi-Fi application, including 802.11b/g/n radio, integrated chip antenna,
certifications, microcontroller, Wi-Fi and IP stacks, HTTP server, and multiple protocols,
such as TCP and UDP. Co-existence with external 2.4GHz transceivers is supported.
• Antenna diversity supported via secondary
RF pin
• IEEE 802.11 b/g/n compliant
• TX power: +16 dBm
WGM160P can be configured to concurrently act as a Wi-Fi client and a Wi-Fi access
point, which is ideal for user friendly device provisioning. WGM160P can natively host C-
applications, removing the need for an external host controller. Alternatively, the Wi-Fi
Module can run in Network Co-Processor (NCP) mode, leaving the complexity of TCP/IP
networking to the module so that the customer’s own host controller can be fully dedica-
ted to processing the customer application tasks. The WGM160P module has highly
flexible host and peripheral hardware interfaces for wide application use.

4. Electrical Specifications
All electrical parameters in all tables are specified under the following conditions, unless stated otherwise:
• Typical values are based on TAMB = 25 °C; VVBAT = 3.3V; Center Frequency = 2,437 MHz.
• Radio performance numbers are measured in conducted mode, based on Silicon Laboratories reference designs using output pow-
er-specific external RF impedance-matching networks for interfacing to a 50 Ω antenna port. Conducted RF measurements include
additional output power reductions to guarantee WiFi and regulatory emissions compliance while connected to the specified anten-
nas which have non-ideal impedance loading.
Refer to Section 4.2 Operating Conditions for more details about operational supply and temperature limits.
4.1 Absolute Maximum Ratings
Stresses above those listed below may cause permanent damage to the device. This is a stress rating only and functional operation of
the devices at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure
to maximum rating conditions for extended periods may affect device reliability. For more information on the available quality and relia-
bility data, see the Quality and Reliability Monitor Report at http://www.silabs.com/support/quality/pages/default.aspx.

Note:
1. When a GPIO is used for analog functions via the APORT, the maximum voltage is VBAT.
2. To operate above the VBAT supply rail, over-voltage tolerance must be enabled according to the GPIO_Px_OVTDIS register.
Pins with over-voltage tolerance disabled have the same limits as all other GPIO (max = VBAT + 0.3 V).

Typical Applications and Connections
5. Typical Applications and Connections
5.1 RF Connections
5.1.1 Antenna Ports
The WGM160P offers two RF ports that support antenna diversity using an internal switch. In applications with only one antenna, the
unused port should be terminated to ground with a 47-51 Ω resistor. Leaving the unused port floating or tying directly to ground will
result in degraded performance. An external antenna connected to either RF port needs to be properly matched with at least -10dB
return loss (VSWR < 2).
5.1.2 Antenna Diversity
In applications where multipath fading is a potential issue, such as indoors, a second antenna can be connected. A firmware feature
can be enabled to automatically determine which of the two antennas gives a better signal, allowing significant improvement in link reli-
ability.
5.2 Multi-Protocol Co-Existance
Packet Transmit Arbitration (PTA) pins are provide to share antenna and optimize co-existence performance with other networks includ-
ing other protocols. See Application Notes "AN1128 Bluetooth Coexistance with Wi-Fi" and "AN1017 Zigbee and Thread Coexistance
with Wi-Fi" for more information.

Soldering Recommendations
9. Soldering Recommendations
The WGM160P is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the
thermal mass of the entire populated PCB, heat transfer efficiency of the oven, and particular type of solder paste used.
• Refer to technical documentations of particular solder paste for profile configurations.
• Avoid using more than two reflow cycles.
• Aperture size of the stencil should be 1:1 with the pad size.
• A no-clean, type-3 solder paste is recommended.
• For further recommendation, please refer to the JEDEC/IPC J-STD-020, IPC-SM-782 and IPC 7351 guidelines.
• Above notes and stencil design are shared as recommendations only. A customer or user may find it necessary to use different
parameters and fine tune their SMT process as required for their application and tooling.

11.1 Qualified External Antenna Types
This device has been certified with an integrated chip antenna as well as external antennas connected to either RF port or both. The
required antenna impedance is 50 Ω.
Table 11.1. Qualified Antennas for WGM160P
Antenna Type
Maximum Gain
Connectorized Coaxial Dipole
2.14 dBi
Any antenna that is of the same general type and of equal or less directional gain as listed in the above table can be used without a
need for retesting in the regulatory areas that have a full modular radio approval (USA, Canada, Korea, Japan). In countries applying
the ETSI standards, like the EU countries, the radiated emissions are always tested with the end-product and the antenna type is not
critical, but antennas with higher gain may violate some of the regulatory limits.
If an antenna of a different type (such as a chip antenna, a PCB trace antenna or a patch) with a gain less than or equal to 2.14 dBi is
needed, it can be added as a permissive change, requiring some radiated emission testing. Antenna types with more gain than 2.14 dBi
may require a fully new certification. Since the exact permissive change procedure is chosen on a case by case basis, please consult
your test house, for example while performing with them the EMC testing of the end-product.
11.2 CE
The WGM160P22A and WGM160P22N module is in conformity with the essential requirements and other relevant requirements of the
Radio Equipment Directive (RED) (2014/53/EU). Please note that every application using the WGM160P22A and WGM160P22N will
need to perform the radio EMC tests on the end product, according to EN 301 489-17. It is ultimately the responsibility of the manufac-
turer to ensure the compliance of the end-product. The specific product assembly may have an impact to RF radiated characteristics,
and manufacturers should carefully consider RF radiated testing with the end-product assembly. A formal Declaration of Conformity
(DoC) is available via https://www.silabs.com/products/wireless/wi-fi/wgm160p-wifi-module.

11.3 FCC
This device complies 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 undesirable operation.
Any changes or modifications not expressly approved by Silicon Labs could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specif-
ic operating instructions for satisfying RF exposure compliance. This transmitter meets both portable and mobile limits as demonstrated
in the RF Exposure Analysis. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter
except in accordance with FCC multi-transmitter product procedures.
OEM Responsibilities to comply with FCC Regulations:
OEM integrator is responsible for testing their end-product for any additional compliance requirements required with this module instal-
led (for example, digital device emissions, PC peripheral requirements, etc.).
• With WGM160P22A and WGM160P22N the antenna(s) must be installed such that a minimum separation distance of 24 mm is
maintained between the radiator (antenna) and all persons at all times.
• The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accord-
ance with FCC multi-transmitter product procedures.
Important Note:
In the event that these conditions cannot be met, then for the FCC authorization to remain valid the final product will have to undergo
additional testing to evaluate the RF exposure, and a permissive change will have to be applied with the help of the customer's own
Telecommunication Certification Body.
End Product Labeling
The variants of WGM160P Modules are labeled with their own FCC ID. If the FCC ID is not visible when the module is installed inside
another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed
module. In that case, the final end product must be labeled in a visible area with the following:
"Contains Transmitter Module FCC ID: QOQWGM160P"
Or
"Contains FCC ID: QOQWGM160P"
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module or
change RF related parameters in the user manual of the end product.

Exception from routine SAR evaluation limits are given in RSS-102 Issue 5.
The models WGM160P22A and WGM160P22N meet the given exemption requirements when the minimum separation distance to hu-
man body is 30 mm.
In other words, RF exposure or SAR evaluation is not required when the separation distance is same or more than stated above. If the
separation distance is less than stated above the OEM integrator is responsible for evaluating the SAR when using the module at its
highest transmission power.
OEM Responsibilities to comply with IC Regulations
The WGM160P modules have been certified for integration into products only by OEM integrators under the following conditions:
• The antenna(s) must be installed such that a minimum separation distance as stated above is maintained between the radiator (an-
tenna) and all persons at all times.
• The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter.
As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still respon-
sible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital
device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE
In the event that these conditions cannot be met, then for the ISEDC authorization to remain valid the final product will have to undergo
additional testing to evaluate the RF exposure, and a permissive change will have to be applied with the help of the customer's own
Telecommunication Certification Body.
End Product Labeling
The WGM160P module is labeled with its own IC ID. If the IC ID is not visible when the module is installed inside another device, then
the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case, the
final end product must be labeled in a visible area with the following:
“Contains Transmitter Module IC: 5123A-WGM160P ”
or
“Contains IC: 5123A-WGM160P”
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module or
change RF related parameters in the user manual of the end product.

Certifications
ISEDC (Français)
Industrie Canada a approuvé l’utilisation de cet émetteur radio (IC: 5123A-WGM160P) en conjonction avec des antennes de type dipo-
laire à 2.14dBi ou des antennes embarquées, intégrée au produit. L’utilisation de tout autre type d’antenne avec ce composant est pro-
scrite.
Ce composant est conforme aux normes RSS, exonérées de licence d'Industrie Canada. Son mode de fonctionnement est soumis aux
deux conditions suivantes:
1. Ce composant ne doit pas générer d’interférences.
2. Ce composant doit pouvoir est soumis à tout type de perturbation y compris celle pouvant nuire à son bon fonctionnement.
Déclaration d'exposition RF
L'exception tirée des limites courantes d'évaluation SAR est donnée dans le document RSS-102 Issue 5.
Les modules WGM160P22A and WGM160P22N répondent aux exigences requises lorsque la distance minimale de séparation avec le
corps humain est de 30 mm.
La déclaration d’exposition RF ou l'évaluation SAR n'est pas nécessaire lorsque la distance de séparation est identique ou supérieure à
celle indiquée ci-dessus. Si la distance de séparation est inférieure à celle mentionnées plus haut, il incombe à l'intégrateur OEM de
procédé à une évaluation SAR.
Responsabilités des OEM pour une mise en conformité avec le Règlement du Circuit Intégré
Le module WGM160P a été approuvé pour l'intégration dans des produits finaux exclusivement réalisés par des OEM sous les condi-
tions suivantes:
• L'antenne (s) doit être installée de sorte qu'une distance de séparation minimale indiquée ci-dessus soit maintenue entre le radiateur
(antenne) et toutes les personnes avoisinante, ce à tout moment.
• Le module émetteur ne doit pas être localisé ou fonctionner avec une autre antenne ou un autre transmetteur que celle indiquée
plus haut.
Tant que les deux conditions ci-dessus sont respectées, il n’est pas nécessaire de tester ce transmetteur de façon plus poussée. Ce-
pendant, il incombe à l’intégrateur OEM de s’assurer de la bonne conformité du produit fini avec les autres normes auxquelles il pour-
rait être soumis de fait de l’utilisation de ce module (par exemple, les émissions des périphériques numériques, les exigences de pé-
riphériques PC, etc.).
REMARQUE IMPORTANTE
ans le cas où ces conditions ne peuvent être satisfaites (pour certaines configurations ou co-implantation avec un autre émetteur), l'au-
torisation ISEDC n'est plus considérée comme valide et le numéro d’identification ID IC ne peut pas être apposé sur le produit final.
Dans ces circonstances, l'intégrateur OEM sera responsable de la réévaluation du produit final (y compris le transmetteur) et de l'ob-
tention d'une autorisation ISEDC distincte.
Étiquetage des produits finis
Les modules WGM160P sont étiquetés avec leur propre ID IC. Si l'ID IC n'est pas visible lorsque le module est intégré au sein d'un
autre produit, cet autre produit dans lequel le module est installé devra porter une étiquette faisant apparaitre les référence du module
intégré. Dans un tel cas, sur le produit final doit se trouver une étiquette aisément lisible sur laquelle figurent les informations suivantes:
“Contient le module transmetteur: 5123A-WGM160P ”
or
“Contient le circuit: 5123A-WGM160P”
L'intégrateur OEM doit être conscient qu’il ne doit pas fournir, dans le manuel d’utilisation, d'informations relatives à la façon d'installer
ou de d’enlever ce module RF ainsi que sur la procédure à suivre pour modifier les paramètres liés à la radio.

11.5 Locating the Module Close to Human Body
When using the module in an application where the radio is located close to human body, the human RF exposure must be evaluated.
FCC, IC, and CE all have different standards for evaluating the RF exposure, and because of this, each standard will require a different
minimum separation distance between the module and human body. Certification of WGM160P allows for the minimum separation dis-
tances detailed in Table 11.2 Minimum Separation Distances for SAR Evaluation Exemption on page 41 in portable use cases (less
than 20 cm from human body). The module is approved for the mobile use case (more than 20 cm) without any need for RF exposure
evaluation.

WGM160P with external reference dipole

FCC
ISED
CE

The RF exposure must always be evaluated using the end-product when transmitting
with power levels higher than 20 mW = 13 dBm.
For FCC and ISED, using the module in end products where the separation distance is smaller than those listed above is allowed but
requires evaluation of the RF exposure in the final assembly and applying for a Class 2 Permissive Change or Change of ID to be
applied to the existing FCC/ISED approvals of the module. For CE, RF exposure must be evaluated using the end-product in all cases.
Note: Placing the module in touch or very close to the human body will have a negative impact on the efficiency of the antenna thus
reducing range.
