Dev kit with hardware-encryption gives projects secure cloud connectivity

September 11, 2015 // By Graham Prophet
Texas Instruments’ TM4C Crypto Connected LaunchPad development kit is aimed at design of IoT gateways and nodes, factory control and automation systems, grid infrastructure, alternative energy and industrial applications.

Based on TI's TM4C129ENCPDT microcontrollers (MCUs), the kit has a fully-available 120-MHz ARM Cortex-4F core with security functions offloaded to hardware accelerators to provide the performance needed for engineers developing applications requiring a secure cloud connection.

The out-of-box demo for the Crypto Connected LaunchPad (EK-TM4C129EXL) includes TI-RTOS, which supports development of multitasking applications to help users develop products requiring an easy and secure Internet connection to the cloud. Pair the TM4C Crypto Connected LaunchPad with WolfSSL software to quickly send encrypted data over on-board Ethernet and view in a browser. Designers also have access to a complimentary download of TI's Code Composer Studio integrated development environment (IDE) programming interface and debugging tool.

The TM4C Crypto Connected LaunchPad provides a low-cost, encryption enabled and easy-to-use evaluation platform. The TI LaunchPad Development Ecosystem offers the hardware, software and community components needed to enable quick and easy design. TI's BoosterPack plug-in daughter boards add functionality to explore different applications.

Features include;

- Advanced security features for data encryption and decryption include on-board Advanced Encryption Standard (AES), Data Encryption Standard (DES), Secure Hash Algorithm (SHA) and Cyclic Redundancy Check (CRC) accelerators to increase performance in secure connected applications. WolfSSL library uses these crypto hardware accelerators to allow a secure SSL/TLS connection with the cloud server.

- Extensive communication options include multiple sensor connectivity peripherals, 10/100 Ethernet MAC & PHY, full- and low-speed USB 2.0 port with in-circuit and external debug connectors, as well as the option to add Wi-Fi connectivity using the low-power SimpleLink Wi-Fi CC3100 BoosterPack.

- A suite of software tools designed to simplify and speed development, including TivaWare, and TI-RTOS-based out-of-box demo for a secure IoT cloud connection.

The TM4C Crypto Connected LaunchPad (EK-TM4C129EXL) is $24.99.
