描述 Description

Connect any microcontroller (MCU) to the Internet of Things (IoT) with the CC3135 device, a dual-band wireless network processor from Texas Instruments. The CC3135 Wi-Fi? Internet-on-a chip? device contains an Arm Cortex-M3 MCU dedicated to Wi-Fi? and internet protocols, in order to offload networking activities from the host MCU. The subsystem includes a dual-band 802.11a/b/g/n radio, baseband, and MAC with a powerful crypto engine for fast, secure Internet connections with 256-bit encryption and a built in power management for best in class low power performance.

The Wi-Fi CERTIFIED? CC3135 device dramatically simplifies the implementation of low-power, with the integrated Wi-Fi Alliance? IoT low power feature.

This generation introduces new capabilities that further simplify the connectivity of things to the Internet. The main new features include:802.11a (5 GHz) support BLE/2.4 GHz radio coexistence Antenna selection Enhanced security withFIPS140-2 Level 1 certification and more. For exact status of FIPS certification for a specific part number, refer to https://csrc.nist.gov/publications/fips. Up to 16 concurrent secure sockets Certificate sign request (CSR) Online certificate status protocol (OCSP) Wi-Fi Alliance? certified for IoT applications with low-power capabilities and more Hostless mode for offloading template packet transmissions Improved fast scan

The CC3135 device is delivered with a slim and user-friendly host driver to simplify the integration and development of networking applications. The host driver can easily be ported to most platforms and operating systems (OS). The driver has 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).

The CC3135 device is part of the SimpleLink? MCU platform, a common, easy-to-use development environment based on a single core software development kit (SDK), rich tool set, reference designs and E2E? community which supports Wi-Fi?, Bluetooth? low energy, Sub-1 GHz and host MCUs.
