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 Marvell’s 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.

3.8 Coexistence use cases

1.

BLE only case

•If WLAN MCU is in sleep or powered down mode, then WLAN_EIP is LOW so BLE firmware would configure antenna
controller to give desired antenna to BLE.

2.

WLAN only case

•

In this case there is no BLE Tx/Rx scheduled so BLE_EIP is LOW.

•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.

•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.

a.

WLAN_EIP was already HIGH, BLE firmware had already given desired antenna to WLAN, so WLAN will
retain the antenna.
