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.
