ATWINC3400 DESIGN‐IN GUIDELINES
Atmel ATWINC3400 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 0 Ohm series resistors on interface traces as place holders in case there is a
need to add some filtering on those line to reduce interference from the Host Processor.
Module can be installed on a product’s carrier board; in this case carrier board must have 20 x 7 (mm)
clearance area (no traces or copper on any layer) under module’s printed antenna. Clearance area 20
mm dimension must be along the carrier board edge.
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: 2ADHKWINC3400” must
be used.
(2) This equipment has been tested and found to comply with the limits for a class B digital device,
pursuant to part 15 of 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 off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
‐ Reorient or relocate the module/product.
‐ Increase the separation between the equipment and module/product.
‐ Consult the dealer or an experienced radio/TV technician for help.
‐ Changes and modifications made to the equipment without the approval of manufacturer
could void the user's authority to operate this equipment.
