ARM Cortex-M3 Processor Core
The ARM Cortex-M3 processor provides the core for a high-performance, low-cost platform that
meets the needs of minimal memory implementation, reduced pin count, and low power
consumption, while delivering outstanding computational performance and exceptional system
response to interrupts. Features include:
The Stellaris family of microcontrollers builds on this core to bring high-performance 32-bit
computing to cost-sensitive embedded microcontroller applications, such as factory automation
and control, industrial control power devices, building and home automation.
For more information on the ARM Cortex-M3 processor core, see the ARM® Cortex™-M3
Technical Reference Manual. For information on SWJ-DP, see the CoreSight™ Design Kit
Technical Reference Manual.
Compact core.
Thumb-2 instruction set, delivering the high-performance expected of an ARM core in the
memory size usually associated with 8- and 16-bit devices; typically in the range of a few
kilobytes of memory for microcontroller class applications.
Exceptional interrupt handling, by implementing the register manipulations required for
handling an interrupt in hardware.
Memory protection unit (MPU) to provide a privileged mode of operation for complex
applications.
