1.3.3 Cortex-M4 processor features and benefits summary
• Tight integration of system peripherals reduces area and development costs
• Thumb instruction set combines high code density with 32-bit performance
• IEEE754-compliant single-precision FPU implemented in all STM32 Cortex-M4
microcontrollers
• Power control optimization of system components
• Integrated sleep modes for low power consumption
• Fast code execution permits slower processor clock or increases sleep mode time
• Hardware division and fast multiplier
• Deterministic, high-performance interrupt handling for time-critical applications
• Memory protection unit (MPU) for safety-critical applications
• Extensive debug and trace capabilities: Serial Wire Debug and Serial Wire Trace
reduce the number of pins required for debugging and tracing.
