Block Diagram

The block diagram of the AMW004 module shows the

main components of the module: an ARM Cortex-M4

microprocessor

and

BCM43362

Wi-Fi

System-in-

Package (SiP) module. The microprocessor and periph-

erals are driven by a 12MHz crystal. The integrated RTC

is driven by a 32.768 kHz crystal.

An integrated

1 MByte serial flash chip may be used to store addition-

al applications, user data or firmware images as part of

an over the air (OTA) update process.

The WLAN subsystem is controlled by WiConnect ena-

bling the module to achieve minimum power consump-

tion when the Wi-Fi networking interface is not re-

quired.

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.
