Silicon Laboratories Finland WGM160P User Manual
WGM160P Wi-Fi® Module Data Sheet
The WGM160P is an ultra low power all-inclusive Wi-Fi® module targeted for applications requiring excellent RF performance, low power consumption, high security, integrated customer applications and fast time to market.
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.
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 Capplications, 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 dedicated to processing the customer application tasks. The WGM160P module has highly
flexible host and peripheral hardware interfaces for wide application use.
This module also supports Gecko OS, a comprehensive software suite designed to simplify your Wi-Fi, application, device management and cloud connectivity development
process.

Electrical Specifications
4. Electrical Specifications
All electrical parameters in all tables are specified under the following conditions, unless stated otherwise:
• Typical values are based on T
• Radio performance numbers are measured in conducted mode, based on Silicon Laboratories reference designs using output power-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 antennas 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 reliability data, see the Quality and Reliability Monitor Report at http://www.silabs.com/support/quality/pages/default.aspx.

WGM160P Wi-Fi® Module Data Sheet
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 reliability.
5.2 Multi-Protocol Co-Existance
Packet Transmit Arbitration (PTA) pins are provide to share antenna and optimize co-existence performance with other networks including other protocols. See Application Notes "AN1128 Bluetooth Coexistance with Wi-Fi" and "AN1017 Zigbee and Thread Coexistance
with Wi-Fi" for more information.

Reset input, active low. This pin is internally pulled up to VBAT. To apply an
RESETn 34
external reset source to this pin, it is required to only drive this pin low during
PD6 35 GPIO
reset, and let the internal pull-up ensure
that reset is released.
PTA RF_ACT pin. These pins can be
used to manage co-existence with another 2.4 GHz radio.
PTA STATUS pin. These pins can be
used to manage co-existence with another 2.4 GHz radio.

7.2 GPIO Functionality Table
A wide selection of alternate functionality is available for multiplexing to various pins. The following table shows the name of each GPIO
pin, followed by the functionality available on that pin. Refer to 7.3 Alternate Functionality Overview for a list of GPIO locations available
for each function.
Full peripheral features and flexibility are not supported with all software architectures. In particular, some restrictions apply when using
Gecko OS. Refer to “UG384 WGM160P Hardware Design Users Guide” for more details.
