2 ATWINC15x0 System Architecture

The following figure shows the ATWINC15x0 system architecture. In addition to its built-in Wi-Fi IEEE-802.11 physical layer and RF front end, the WINC ASIC contains an embedded APS3S-Cortus 32-bit CPU to run the WINC firmware. The firmware comprises the Wi-Fi IEEE-802.11 MAC layer and embedded protocol stacks which offload the host MCU. The components of the system are described in the following sub-sections.
