General Description
1 General Description
The AMW006 and AMW106 modules from Zentri
combine a microcontroller with a BCM43362 Wi‐Fi
device to provide an advanced stand‐alone Wi‐Fi and
networking solution.
The term AMWx06 refers to both modules.
An integrated module avoids difficult RF layout and
enables designers to rapidly embed Wi‐Fi and secure
networking functionality into virtually any device.
The ZentriOS 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.
includes an integrated
The Wi‐Fi device from
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
‐M4.
ARM® 32‐
The AMW006/AMW106 microcontroller core operates
at a frequency up to 84/100MHz providing up to 125
DMIPS or 1.25 DMIPS/MHz (Dhrystone 2.1).
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, CE approval for use in
Europe, TELEC/MIC approval for use in Japan and
related approvals for use in other countries.
The AMW006 has 96KB of RAM.
The AMW106 has 128KB of RAM.
The AMWx06 module offers extensive I/O and
peripheral interfaces listed below, and provides
additional interface combinations by leveraging
multiplexing and alternate function capabilities.

2 x SPI interfaces (1 master, 1 slave)

Block Diagram
2 Block Diagram
Figure 1 is a block diagram of the AMWx06 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 Zentri secure over the air (OTA) update process.
The WLAN subsystem is controlled by ZentriOS 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).
