1. GENERAL DESCRIPTION
1-1. PRODUCT OVERVIEW AND FUNCTIONAL DESCRIPTION
AzureWave presents AW-CU277 Wi-Fi & Bluetooth 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 microcontroller platform using
the Marvell Avastar® 88W8777 Wi-Fi & Bluetooth System-on-Chip (SoC) and Marvell Easy Connect
software. Adding new enhancements and capabilities, the second-generation Smart Energy hardware
platform is built with a new high-performance Marvell Cortex-M3 microcontroller (Marvell 88MC200)
optimized to run Marvell’s Easy Connect software. It is paired with Marvell’s industry leading low-power
Wi-Fi & Bluetooth SoCs to provide best-in-class performance and rich features including IEEE 802.11n,
Beamforming, Access-Point mode and Wi-Fi Direct.
The AW-CU277 is powered by production quality, field-tested Marvell 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, Internetbased 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.
