WGM110 Wizard Gecko Wi-Fi

Module

Data Sheet

The Wizard Gecko WGM110 is an all-inclusive Wi-Fi

Module targeted for applications

where good RF performance, low-power consumption, and easy application develop-

ment, together with fast time to market, are key requirements. WGM110 has excellent

RF performance and can provide long range with robust wireless connectivity.

The WGM110 Module integrates all of the necessary elements required for an IoT Wi-Fi

application, including an 802.11b/g/n radio, integrated chip antenna (WGM110A) or an

u.FL connector for an external antenna (WGM110E), certifications, a microcontroller,

Wi-Fi and IP stacks, an HTTP server, and multiple protocols, such as TCP and UDP.

WGM110 can act as a Wi-Fi client or be used as a Wi-Fi access point, making the provi-

sioning of the device as easy as surfing on the web. WGM110 can host BGScript™ end

user applications, which means applications can be designed without relying on an ex-

ternal microcontroller. 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 cus-

tomer’s own host controller can be fully dedicated to processing the customer applica-

tion tasks. The WGM110 Module also has highly flexible hardware interfaces which al-

lows connection to different peripherals and sensors.

In addition to the Wi-Fi Module itself, Silicon Labs offers support to guide and help de-

velopers in using WGM110 to build IoT applications, enabling a quick time to market.

WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Interfaces 3. Interfaces This section describes the features and functionalities of the available host, peripheral, debug, and RF test interfaces. 3.1 Host Interfaces There are three available host interfaces one of which can be used to connect an external host, typically an MCU, to the WGM110 WiFi Module and use it as a Wi-Fi modem. 3.1.
PAGE 10
WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Interfaces Figure 3.1. Recommended Schematics: Connecting WGM110 with an External Host Using the UART Interface (USART0 Loc 0) Note: In the figure above the UART interface is wired using USART0 Location 0 pins. Note: If handshaking is required, then connect external host CTS to PE13 and external host RTS to PE12. Note: A programming connector, as shown in the schematics, must be available in the design to enable WGM110 firmware update. 3.1.
PAGE 11
WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Interfaces The following figure shows the recommended schematics for connecting WGM110 with an external host over SPI. In addition to the selected USART/SPI port signals, one additional GPIO pin must be dedicated to be used as a notify signal to inform the SPI Master that data from module is available. Note: The SPI host interface can only be used as a SPI Slave. Figure 3.2.
PAGE 12
WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Interfaces The next figure shows the recommended schematics for connecting WGM110 Module with an external host over USB. Figure 3.3. Connecting the WGM110 Module with an External Host using the USB Interface Note: When using the USB interface, the VBUS signal should be connected to the USB host's VBUS line. Note: If the VBUS line is not available on the host, the module's VBUS signal should be connected to the VDDCPU.

WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Interfaces 3.2.1 USART (UART/SPI) The Universal Synchronous/Asynchronous Receiver/Transmitter (USART) provides a flexible serial I/O interface. It supports full duplex asynchronous UART communication up to 6 Mbps. Both SPI Master and Slave modes are also supported up to 6 Mbps. Software emulated RTS/CTS handshaking is supported. For this reason there may be up to two extra data bytes transmited by the Module after the host's RTS has been pulled high. Figure 3.

WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Interfaces 3.3.1 ARM Serial Wire Debug (SWD) The WGM110 Module contains a 2-wire ARM SWD interface for programming and debugging. It is recommended that the pads of this interface are exposed in the application design to allow firmware updates and debugging. 3.3.2 Device Firmware Upgrade (DFU) The firmware can be updated over the configured host interface (UART, SPI, or USB) using the Device Firmware Upgrade (DFU) protocol.

WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Module Software 4. Module Software This section gives a short overview of the software provided with the WGM110 Module and describes the basic methods of using the Module. The figure below shows the block diagram of the software provided with the WGM110 Module and how it relates to the software on the external host. Figure 4.1.
PAGE 16
WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Module Software The WGM110 Module can also be used in a mixed mode, where both the NCP and Stand-alone approaches are used in parallel. In this case the BGScript application on the module can be run completely independent from any MCU action. Normally the approach is to automate certain processes in BGScript (e.g. Wi-Fi network scanning and connection) to relieve the host from doing these.

WGM110 Wizard Gecko Wi-Fi® Module Data Sheet Hardware Design Guidelines The layouts shown in the figure below will result in severely degraded RF-performance. Figure 5.2. Non-optimal Application PCB Layouts for WGM110A Module The impact of the size of the ground plane on the achievable range of the maximum range available for the WGM110A Module is shown below. As can be seen from the image, the curve indicates that the maximum range is achieved with an approximately 35 - 40 mm wide ground plane.
