Introduction 1.1 Product Overview AzureWave presents AW-CU345 Wi-Fi/BT Microcontroller Smart Energy Platform Solution provides a highly cost-effective, flexible and easy to-use hardware/software platform to build a new generation of connected, smart devices. These smart-connected devices enable device to deliver a broad-range of services to consumers including energy-management, demand-response, home automation and remote access. This allows a user to manage comfort and convenience, also run diagnostics and receive alerts and notifications, in addition to managing and controlling the device. Developers can leverage the rich connectivity features of these new smart devices to create a new generation of innovative new applications and services. The platform builds upon the success of Marvells first-generation Wi-Fi/BT microcontroller platforms using the Marvell/Dialog 88MW320/DA14585 Wi-Fi/BT System-on-Chip (SoC), a 4MByte QSPI flash memory and Marvell Easy Connect software. 1.2 Features 1.2.1 WLAN MCUs of AW-CU345

From WLAN MCU WLAN_EIP is always HIGH because WLAN is doing Tx/Rx. On WLAN_EIP rising edge, BLE firmware will configure antenna controller and gives desired antenna to WLAN. 3. BLE + WLAN case During BLE activity BLE_EIP will be HIGH. If BLE priority is HIGH then, a. WLAN firmware will block WLAN Tx and pull WLAN_EIP to LOW. b. On WLAN_EIP falling edge, BLE firmware will configure antenna controller to give desired antenna to BLE. If BLE priority is LOW then, a. WLAN_EIP was already HIGH, BLE firmware had already given desired antenna to WLAN, so WLAN will retain the antenna.
