AMW004 • 802.11b/g/n WICED™ Module

General Description, Section 1

ADS-MW004-100D8 • Preliminary Data Sheet Page | 1

1 General Description

The AMW004 module from ACKme Networks combines

a SAM4S microcontroller with a BCM43362 Wi-Fi device

and on-board antenna to provide an advanced stand-

alone Wi-Fi and networking solution.

An integrated module avoids difficult RF layout and en-

ables designers to rapidly embed Wi-Fi and secure net-

working functionality into virtually any device.

Custom applications may be developed for the module

using the Broadcom WICED Software Development Kit.

Alternately, the ACKme Networks WiConnect serial-to-

Wi-Fi application may be used to fast-track module in-

tegration into end products.

With dimensions of just 0.7 x 1.25 inches and a wide

temperature range, the module is suitable for integra-

tion into most embedded applications.

The Wi-Fi device from Broadcom includes an integrated

RF transmit power amplifier and provides superior

Wi-Fi performance and full compatibility with all 2.4GHz

802.11b/g/n Wi-Fi networks. An external antenna op-

tion provides additional performance and flexibility if

required.

The SAM4S microprocessor from Atmel is based on a

high-performance ARM® Cortex™-M4 32-bit RISC core

operating at a frequency up to 120MHz. The SAM4S

incorporates high-speed embedded memory including

1MB Flash memory and 128kB SRAM, and an extensive

range of enhanced I/Os and peripherals.

The AMW004 module connects a large number of

SAM4S pins to capitalize on the extensive SAM4S I/O

and peripheral interfaces. The module supports the fol-

lowing list of interfaces, and provides additional inter-

face combinations by leveraging SAM4S I/O multiplex-

ing and alternate function capabilities.

 10 x 12-bit A/D converters

 1 x 12-bit D/A converters

 1 x 4-Wire USART interface

 1 x 4-Wire, 2 x 2-Wire UART interfaces

 1 x SPI master/slave bus

 2 x I2C interfaces

 1 x I2S interface

 1 x USB full-speed device interface

 12 x edge/level sensitive wake inputs

The module may be powered by a single 3.3V power

supply. A separate power supply pin for the Wi-Fi sub-

system is provided to minimize power supply noise

coupling into the WLAN subsystem, and to enable addi-

tional control for power sensitive applications.

Power consumption in various states is determined by

the power consumption of the SAM4S microprocessor

and BCM43362 Wi-Fi chip. The power supply to the

Wi-Fi chip and radio subsystem may be externally knife-

switched under software control to achieve minimum

power consumption in an ultra-low power backup state

described in the SAM4S datasheet.

The microprocessor may be woken from low power

states by connecting any of 12 different module pins, or

by other methods including an internal RTC/RTT timer

or supply monitor as described in the SAM4S datasheet.

The module incorporates a 32.768kHz crystal to main-

tain an accurate real time clock. A 32kHz clock output is

available on a dedicated module pin in both active and

SAM4S powerdown modes. The 32kHz clock output

may be used to drive the clock input of other system

devices. This avoids the need for an additional crystal

thereby minimizing total system cost.

Application debugging with a software debugger such

as gdb is enabled with a standard JTAG (or Serial Wire

Debug) interface.

The module has FCC modular approval for use in the

United States, and CE approval for use in Europe and

other countries.

2 Block Diagram

Figure 1 is a block diagram of the AMW004 module. The

main components of the module are an AT91SAM4S16C

microprocessor and BCM43362 Wi-Fi System-in-

Package (SiP) module. The SAM4S ARM processor and

peripherals are driven by a 12MHz crystal, the integrat-

ed RTC is driven by a 32.768kHz crystal. An integrated

1MByte serial flash chip may be used to store additional

applications, user data or firmware images as part of an

over the air (OTA) update process.

A dedicated power supply input to the WLAN subsys-

tem is controlled by an application running on the

SAM4S, enabling the module to achieve minimum pow-

er consumption when the Wi-Fi networking interface is

not required.

The module includes an antenna diversity switch. The

switch enables static or dynamic selection of the on-

board antenna or an external antenna plugged to the

u.FL connector.

Design Guidelines, Section 6

ADS-MW004-100D8 • Preliminary Data Sheet Page | 10

6 Design Guidelines

6.1 Recommended PCB Footprint

Figure 3. AMW004 Recommended Footprint (Top)

All dimensions are in thousands of an inch unless oth-

erwise marked. The addition of castellation’s on the

periphery of the module carrier board directly beneath

the end of the module nearest the antenna (as depict-

ed in Figure 3) are strongly recommended.

6.2 Routing Recommendations

When designing a carrier board, the addition of ground

fill directly underneath the AMW004 module, rather

than signal or power traces, is recommended. If traces

must be routed directly beneath the module, avoid

routing directly under tests pads or under the end of

the module close to the antenna. Failure to comply

with these recommendations may result in degraded

performance of WLAN functionality.

6.5 Application Examples

This section provides circuit examples demonstrating

how to configure the module to meet various applica-

tion requirements.

Power Supply 6.5.1

The module requires at least 10µF of bulk capacitance

between VDD_3V3 pin 29 and ground and between

VDD_3V3_WIFI pin 2 and ground. The WLAN radio per-

formance may be significantly degraded if ground Pins

44-54 near the antenna are not connected to a solid

ground.

For applications that do not require separate control of

the WLAN power supply, the VDD_3V3 and

VDD_3V3_WIFI power supply pins may be connected

together as shown in .

Alternately, for applications that require finer control

over power consumption, the VDD_3V3_WIFI supply

can be dynamically driven. This is achieved using a sep-

arate regulator, or with a P-channel MOSFET as shown

in . The WIFI_EN gate enable signal may be connected

to any available GPIO on the module and controlled by

software to power on or off the WLAN subsystem as

required.

Programming and Debug 6.5.2

The module may be programmed using the WICED SDK

by connecting power and a JTAG JLINK header as shown

in Figure 7. JTAG adapters from Olimex, Segger or oth-

ers may be used as described in the WICED SDK docu-

mentation.

Figure 7. Connecting the AMW004 Module for Programming and Debug

Operation using WiConnect 6.5.3

The AMW004 module is pre-installed with WiConnect,

ACKme Networks feature-rich and reliable serial Wi-Fi

networking application with easy-to-use commands.

The module only requires power and a connection to a

serial interface such as UART or SPI. A host processor

connects to pins 23/24 (or 38/39) as shown in Figure 8

if the USART1 (or USART0) serial interface is used.

7.1 United States

The ACKme Networks AMW004 module has received

Federal Communications Commission (FCC) CFR47 Tele-

communications, Part 15 Sub-part C “Intentional Radia-

tors” modular approval in accordance with Part 15.212

Modular Transmitter approval. Modular approval al-

lows the end user to integrate the AMW004 module

into a finished product without obtaining subsequent

and separate FCC approvals for intentional radiation,

provided no changes or modifications are made to the

module circuitry. Changes or modifications could void

the user’s authority to operate the equipment. The end

user must comply with all of the instructions provided

by the Grantee which indicate installation and/or oper-

ating conditions necessary for compliance.

The finished product is required to comply with all ap-

plicable FCC equipment authorization, regulations, re-

quirements, and equipment functions not associated

with the transmitter module portion. For example,

compliance must be demonstrated to regulations for

other transmitter components within the host product;

to requirements for unintentional radiators (Part 15

Sub-part B “Unintentional Radiators”), such as digital

devices, computer peripherals, radio receivers, etc.; and

to additional authorization requirements for non-

transmitter functions on the transmitter module (i.e.

Verification, or Declaration of Conformity) (e.g., trans-

mitter modules may also contain digital logic functions)

as appropriate.

Labeling and User Information 7.1.1

Requirements

The AMW004 module has been labelled with a unique

FCC ID number, and if the FCC ID is not visible when the

module is installed inside another device, then the out-

side of the finished product into which the module is

installed must also display a label referring to the en-

closed module. This exterior label can use wording as

follows:

The user manual for the product should include the fol-

lowing statement:

Contains FCC ID: 2ABPY-61F8D

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 un-

desired operation.

This equipment has been tested and found to com-

ply with the limits for a Class B digital device, pursu-

ant to part 15 of the FCC Rules. These limits are de-

signed to provide reasonable protection against

harmful interference in a residential installation.

This equipment generates, uses and can radiate ra-

dio frequency energy and if not installed and used in

accordance with the instructions, may cause harm-

ful interference to radio communications. However,

there is no guarantee that interference will not oc-

cur in a particular installation. If this equipment

does cause harmful interference to radio or televi-

sion 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 receiving antenna.

 Increase the separation between the equip-

ment and receiver.

 Connect the equipment into an outlet on a cir-

cuit different from that to which the receiver is

connected.

 Consult the dealer or an experienced radio/TV

technician for help.

RF Exposure 7.1.2

All transmitters regulated by FCC must comply with RF

exposure requirements. OET Bulletin 65, Evaluating

Compliance with FCC Guidelines for Human Exposure to

Radio Frequency Electromagnetic Fields, provides assis-

tance in determining whether proposed or existing

transmitting facilities, operations or devices comply

with limits for human exposure to Radio Frequency (RF)

fields adopted by the Federal Communications Com-

mission (FCC). The bulletin offers guidelines and sugges-

tions for evaluating compliance.

If appropriate, compliance with exposure guidelines for

mobile and unlicensed devices can be accomplished by

the use of warning labels and by providing users with

information concerning minimum separation distances

from transmitting structures and proper installation of

antennas.

The following statement must be included as a CAU-

TION statement in manuals and OEM products to alert

users of FCC RF exposure compliance:

If the AMW004 module is used in a portable application

(i.e., the antenna is less than 20 cm from persons dur-

ing operation), the integrator is responsible for per-

forming Specific Absorption Rate (SAR) testing in ac-

cordance with FCC rules 2.1091.

External Antenna 7.1.3

Modular approval in the United States is permitted with

the use of the integrated antenna ONLY. If an external

antenna is used with the AMW004 module, additional

testing of the end product is needed to meet FCC re-

quirements.
