Processor state automatically saved on interrupt entry and restored on interrupt exit, with no
instruction overhead
• Version 2.0
• Thumb-2 (ISA) subset consisting of all base Thumb-2 instructions, 16-bit and 32-bit.
• Harvard processor architecture enabling simultaneous instruction fetch with data load/store.
• Three-stage pipeline.
• Single cycle 32-bit multiply.
• Hardware divide.
• Thumb and Debug states.
• Handler and Thread modes.
• Low latency ISR entry and exit.
• SysTick Timer
• Nested Vectored Interrupt Controller
• The Cortex-M3 processor is a high performance 32-bit processor designed for the
• outstanding processing performance combined with fast interrupt handling
microcontroller market. It offers significant benefits to developers, including:
– 24-bit down counter
– Self-reload capability
– Flexible System timer
– Thirty Two maskable external interrupts
– Sixteen priority levels
– Processor state automatically saved on interrupt entry, and restored on
– Dynamic reprioritization of interrupts
– Priority grouping
– Support for tail-chaining and late arrival of interrupts
back-to-back interrupt processing without the overhead of state saving and restoration
between interrupts.
