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.
The memory protection unit (MPU) improves system reliability by defining the memory
attributes (such as read/write access permissions) for different memory regions. It provides
up to eight different regions and an optional predefined background region.
Owing to its embedded ARM core, the STM32L15xxx is compatible with all ARM tools and
software.

entering run mode.
