General Description, Section 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 standalone Wi-Fi and networking solution.

An integrated module avoids difficult RF layout and enables designers to rapidly embed Wi-Fi and secure networking 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-toWi-Fi application may be used to fast-track module integration into end products.

With dimensions of just 0.7 x 1.25 inches and a wide temperature range, the module is suitable for integration 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 option 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 following list of interfaces, and provides additional interface combinations by leveraging SAM4S I/O multiplexing 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 subsystem is provided to minimize power supply noise coupling into the WLAN subsystem, and to enable additional 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 knifeswitched 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 maintain 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.

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-inPackage (SiP) module. The SAM4S ARM processor and peripherals are driven by a 12MHz crystal, the integrated 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 subsystem is controlled by an application running on the SAM4S, enabling the module to achieve minimum power 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 onboard antenna or an external antenna plugged to the u.FL connector.

AMW004 • 802.11b/g/n WICED™ Module

All dimensions are in thousands of an inch unless otherwise 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 depicted in Figure 3) are strongly recommended.

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 application requirements.

Figure 5. Common Power Supply

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 performance 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 separate 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.

Figure 6. Gated WLAN Power Supply

AMW004 • 802.11b/g/n WICED™ Module

The AMW004 module is pre-installed with WiConnect, ACKme Networks feature-rich and reliable serial Wi-Fi networking application with easy-to-use commands.

7.1 United States

The ACKme Networks AMW004 module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Sub-part C “Intentional Radia-

tors” modular approval in accordance with Part 15.212

Modular Transmitter approval. Modular approval allows 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 operating conditions necessary for compliance.

The finished product is required to comply with all applicable FCC equipment authorization, regulations, requirements, 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 nontransmitter functions on the transmitter module (i.e. Verification, or Declaration of Conformity) (e.g., transmitter 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 outside of the finished product into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording as follows:

The user manual for the product should include the following statement:

AMW004 • 802.11b/g/n WICED™ Module

To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended.
