ATWILC1000-MR110UB DESIGN-IN GUIDLINES

Atmel ATWILC1000-MR110UB module provides Wi-Fi capabilities to a Host Processor.

The following connections are required for the proper operation:

- 3.3V power supply,

- VDDIO,

- CHIP_EN, RESET control signals,

- SPI or SDIO interface.

It is recommended to install 75 Ohm series resistors on interface traces to filter our interference from the

Host Processor in “Receive” mode.

Module can be installed on a product’s carrier board. A uFL connected antenna can be installed to the top

of the module.

Each module has label with FCC ID, however product User Manual must contain the following statement:

“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 undesired operation”.

Module must be installed into the end product to provide a separation distance of at least 6.5 cm from all

persons and must not be co-located or operating in conjunction with any other antenna or transmitter.

If module’s label is not visible when installed, then an additional permanent label referring to the enclosed

module: “Contains Transmitter Module FCC ID: 2ADHKATWILC1000U” must be used.
