Texas Instruments Stellaris ARM Cortex-M4F Microcontrollers and Development Tools

Texas Instruments recently announced the new low power, floating-point Stellaris® Cortex™-M4F microcontroller generation. All of the new LM4Fx Stellaris microcontrollers provide floating point for performance headroom and best-in-class power consumption to address portability and power budgets. Developers can also select from a variety of high-performance analog, memory and connectivity options to best satisfy design parameters across a broad range of applications, such as industrial automation, motion control, health and fitness and more. The new Stellaris MCUs are the first Cortex-M-based microcontrollers to be built on 65 nanometer (nm) technology, paving the roadmap to higher speeds, larger memory and even lower power.

To ease design and speed time to market, TI’s free license and royalty-free StellarisWare® software is available for download and is unmatched in breadth and ease-of-use. StellarisWare software includes hundreds of example projects, application and peripheral libraries and open source stacks. To conserve flash memory, TI also offers the software pre-loaded in ROM. Supported by five popular IDEs, Stellaris microcontroller kits jumpstart design in 10 minutes or less. Developers can easily scale designs and reuse code across the entire code compatible Stellaris Cortex-M microcontroller platform.

LM4F232 Evaluation Kits:

The new evaluation kit for LM4F MCUs continues the Stellaris tradition of fun, easy-to-use eval kits. It features a 144-pin device, a color OLED display, USB OTG, a micro SD card, a coin cell battery for use with the Stellaris low-power hibernate, a temperature sensor, a three axis accelerometer for motion detection, and easy-access through-holes to all of the available device signals. In the box are all the tools needed to develop and prototype your product, including the eval board, a complete StellarisWare firmware package, comprehensive documentation with lots of example applications, and the required cables. The kit is available in five tool options.
