1.1 Product Overview
AzureWave presents AW-CU442 802.11b/g/n 1T1R WLAN and Bluetooth low energy (5.0)
Microcontroller 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 architecture features the Realtek RTL8721CSM-VA1 integrated single-chip low power dual band
(2.4G) wireless LAN and Bluetooth Low Energy (5.0) communication controller. It consists of high-
performance MCU (latest architecture v8m, Cortex-M4F instruction compatible) named KM4, a low
power MCU (v8m, Cortex-M0 instruction compatible) named KM0, WLAN (802.11b/g/n) MAC, a
1T1R capable WLAN baseband, RF, Bluetooth and peripherals.
The AW-CU442 is powered by production quality, field-tested Realtek Easy Connect software that
includes a rich set of software components that work together to support the development of Smart
Energy devices, and enable these devices to connect to mobile clients such as smart-phones,
Internet-based Cloud and Smart-Grid services. The feature-rich software stack enables OEMs to
focus on application-specific software functionality, thus enabling rapid development and reduced
software development costs and risks.
