SafeRTOS for TEXAS INSTRUMENTS LM3S9B96 Cortex-M3

The LM3S9B96 is a Cortex M3 microcontroller from Texas Instruments that comes with a pre-built version of SafeRTOS embedded in ROM. Applications running on the LM3S9B96 can link to and use the ‘ROMed’ copy of SafeRTOS in commercial applications without paying any license fees. Its small size and simplicity makes SafeRTOS ideal for use in a wide range of embedded application areas, including those which require certification.

SafeRTOS has been independently certified to ease application certification especially in Industrial and Medical applications. Users can buy a separate Design Assurance Pack which contains all the certification evidence for IEC61508 SIL3 and FDA510(k).
The information provided in this section relates only to ROMed versions of SafeRTOS. There are other versions of SafeRTOS which are available as ‘C’ source code with certification evidence for a wide range of processors.

STM32L ultra-low-power ARM Cortex-M3 MCUs for Energy-Lite apps

STMicroelectronics has announced the extension of its 32-bit STM32L series of microcontrollers to include devices with memory densities of 256 and 384 Kbytes, offering a flash memory range from 32 up to 384 Kbytes for embedded applications. The series is now entering into volume manufacturing and the first devices, offering 64 and 128-Kbyte memory densities, are expected to be available in production maturity by the end of March 2011. STM32L series MCUs with 32-Kbyte memories will follow in Q2 2011.
First ultra-low-power ARM Cortex-M3 MCUs are available from a top-10 silicon supplier and offer 33 DMIPS performance at 32MHz (max). The series is part of ST’s extensive 32-bit STM32 family, which now has more than 180 variants offering complete pin, software, and peripheral compatibility for maximum flexibility.
