Texas Instruments CC3135 SimpleLink™ Wi-Fi® Network Processor

Texas Instruments CC3135 SimpleLink™ Wi-Fi® Dual-band Network Processor connects any microcontroller to the Internet of Things (IoT). The CC3135 Internet-on-a chip™ device contains an Arm® Cortex®-M3 MCU dedicated to Wi-Fi and internet protocols, resulting in an offload of the networking activities from the host MCU.

The subsystem features a dual-band 802.11a/b/g/n radio, baseband, and MAC with a powerful crypto engine. These features offer a fast, secure Internet connection with 256-bit encryption and built-in power management for best-in-class low-power performance. The Wi-Fi CERTIFIED® CC3135 device simplifies low-power implementation with the integrated Wi-Fi Alliance® IoT low-power option.

The Texas Instruments CC3135 provides a slim and user-friendly host driver, simplifying the integration and development of networking applications. The host driver can effortlessly be ported to most platforms and operating systems (OS). The driver offers a small memory footprint and can run on 8-bit, 16-bit, or 32-bit microcontrollers with any clock speed (no performance or real-time dependency).
