AMW006 • Embedded Wi-Fi Networking Solution
General Description, Section 1
1 General Description
The AMW006 module from ACKme Networks combines
a microcontroller with a BCM43362 Wi-Fi device to
provide an advanced stand-alone 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.
The ACKme Networks WiConnect serial-to-Wi-Fi application, pre-programmed into all modules, may be used
to fast-track module integration into end-products.
With dimensions of just 20.3mm x 15.2mm 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. Connections for two external antennas provide applications with maximum
radio range and mechanical design flexibility.
The microprocessor is based on a high-performance
ARM® 32-bit Cortex™-M4 operating at a frequency up
to 84MHz providing 1.25 DMIPS/MHz. An extensive
range of enhanced I/Os and peripherals are also available.
The AMW006 module offers extensive I/O and peripheral interfaces listed below, and provides additional
interface combinations by leveraging multiplexing and
alternate function capabilities.
The module is powered by a 3.3V power supply, a separate WLAN power supply pin is provided to minimize
noise coupling into the WLAN subsystem.
Various powersave modes offer ultra-low power operation. Wake from low power sleep mode is possible using IO pins or the internal real-time clock, and wake
from ultra-low power standby mode is achieved using
the dedicated wake pin.
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
power save 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.
The module has FCC & IC modular approval for use in
the United States and Canada, and CE approval for use
in Europe and other countries.
2 x 4-Wire UART interfaces
2 x SPI interfaces (1 master, 1 slave)
21 x GPIOs
9 x 12-bit A/D converters
14 x PWM outputs

Figure 1 is a block diagram of the AMW006 module. The
main components of the module are a microprocessor
and BCM43362 Wi-Fi System-on-Chip (SoC). The processor and peripherals are driven by a 26MHz crystal.
The integrated real-time clock (RTC) is driven by a
32.768kHz crystal. An on-board 1MByte serial flash
chip may be used to store user data and configuration,
additional applications, and firmware images as part of
the ACKme secure over the air (OTA) update process.

The WLAN subsystem is controlled by WiConnect 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 control of the external
antenna(s).
