ARM® Cortex®-M3 core with MPU
The ARM® Cortex®-M3 processor is the industry leading processor for embedded systems.
It has been developed to provide a low-cost platform that meets the needs of MCU
implementation, with a reduced pin count and low-power consumption, while delivering
outstanding computational performance and an advanced system response to interrupts.
The ARM® Cortex®-M3 32-bit RISC processor features exceptional code-efficiency,
delivering the high-performance expected from an ARM core in the memory size usually
associated with 8- and 16-bit devices.

1. The startup on communication line wakes the CPU which was made possible by an EXTI, this induces a delay before
entering run mode.
