Texas Instruments has revealed two single-chip MCUs with built-in Wi-Fi connectivity designed for the IoT.

The SimpleLink CC3100 and CC3200 chips claim the industry's lowest power consumption for battery-operated devices with a low power radio and advanced low power modes. They incorporate features that require no prior Wi-Fi experience to get a product connected, including quick connection, cloud support, Internet and robust security protocols. Multiple provisioning options such as SmartConfig technology, WPS and AP mode support connectivity with phone, tablet app or a web browser.

The Wi-Fi network processor sub-system features a Wi-Fi Internet-on-a-Chip and contains an additional dedicated ARM MCU that completely offloads the applications MCU. This sub-system includes an 802.11 b/g/n radio, base band, and MAC with a crypto engine for fast, secure Internet connections with 256bit encryption.

With a QFN package and fully integrated RF and analogue, the devices allow developers to create a low cost, compact and easy to use system by placing the device directly on a PCB. TI also provides various kits and software tools, a soon to be released certified TI module, reference designs, sample applications, development documentation, and TI E2E community support.

The SimpleLink Wi-Fi solutions are available, with the CC3100 at $6.70 per 1,000 units, and the CC3200, at $7.99.
