Cypress combination chip extends battery life for IoT devices

A low power Wi-Fi and Bluetooth combination chip from Cypress Semiconductor is interoperable with 802.11ac access points. It extends battery life, says Cypress, by virtue of its 28nm architecture.

The Cypress CYW43012 delivers low power Wi-Fi and Bluetooth connectivity to extend battery life for wearables, smart home products and portable audio applications. The CYW43012 prolongs battery life by leveraging 28nm process technology to reduce power consumption up to 70 per cent in receive mode and up to 80 per cent in sleep mode when compared to current solutions, claims Cypress. The CYW43012 is IEEE 802.11a/b/g/n-compliant and 802.11ac-Friendly, meaning it is interoperable with 802.11ac access points using standard modes. This enables it to offer higher throughput and better energy efficiency, along with the enhanced security and coverage of 802.11ac Wi-Fi networks, according to Cypress.

The CYW43012’s co-existence engine enables dual-band 2.4 and 5.0GHz Wi-Fi and dual-mode Bluetooth/Bluetooth low energy 5.0 applications to be performed simultaneously. Cypress supports the CYW43012 with WICED Studio IoT development platform, which streamlines the integration of wireless technologies for developers.

The 802.11ac-Friendly capability combined with Cypress’ multi-radio co-existence engine provide cleaner air with high-fidelity connections and enhanced range, say Cypress. Both factors are critical as today’s increasing number of wireless devices compete for airtime.

The Cypress WICED Studio IoT development platform features an integrated and interoperable wireless software development kit (SDK). The SDK includes Wi-Fi and Bluetooth protocol stacks, as well as simplified application programming interfaces that free developers from needing to learn complex wireless technologies. For IoT dual-mode connectivity, the SDK supports Cypress’ Wi-Fi and Bluetooth combination solutions and its Bluetooth and Bluetooth low energy devices. The SDK enables cloud connectivity in minutes, claims Cypress, with robust libraries that integrate popular cloud services such as Amazon Web Services, IBM Bluemix, Alibaba Cloud, and Microsoft Azure, with services from private cloud partners. WICED also supports iCloud remote access for Wi-Fi-based accessories that support Apple HomeKit, which enables hub-independent platforms that connect directly to Siri voice control and the Apple Home app remotely.

Cypress’ WICED Studio connectivity suite is microcontroller-agnostic and provides support for third-party microcontrollers to address the needs of complex IoT applications. The platform also enables cost-efficient solutions for simple IoT applications by integrating microcontroller functionality into the connectivity device. Wi-Fi and Bluetooth protocol stacks can run transparently on a host microcontroller or in embedded mode, allowing for flexible platform architectures with common firmware.

Cypress is sampling the CYW43012 to lead customers now. Full production is expected in Q4 2017.
