ARM Cortex-M3 Processor Core
2 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:
 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.
 Full-featured debug solution with a:
â Serial Wire JTAG Debug Port (SWJ-DP)
â Flash Patch and Breakpoint (FPB) unit for implementing breakpoints
â Data Watchpoint and Trigger (DWT) unit for implementing watchpoints, trigger resources,
and system profiling
â Instrumentation Trace Macrocell (ITM) for support of printf style debugging
â Trace Port Interface Unit (TPIU) for bridging to a Trace Port Analyzer
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.
