System Architecture

The STM32 family is based on CORTEX-M3 core.
The standard peripheral are connected to the core using AHB (bus via AHB-APB1 bus and AHB-APB2).
Important is remember that:
At power on all the peripheral clock are turn off.
This means that for using a peripheral is necessary: configure it but is also necessary turn on the clock on it.
Below there is the STM32F107 system architecture.

What is Cortex M3

The ARM Cortex™-M3 processor is the industry-leading 32-bit processor for highly deterministic real-time applications and has been specifically developed to enable partners to develop high-performance low-cost platforms for a broad range of devices including microcontrollers, automotive body systems, industrial control systems and wireless networking and sensors.
The processor delivers outstanding computational performance and exceptional system response to events while meeting the challenges of low dynamic and static power constraints.
The processor is highly configurable enabling a wide range of implementations from those requiring memory protection and powerful trace technology through to extremely cost sensitive devices requiring minimal area.



Why Cortex-M3

Delivering higher performance and richer features
Introduced in 2004 and recently updated with new technologies and configurability, the Cortex-M3 is the mainstream ARM processor developed specifically with microcontroller applications in mind.

Performance and Energy Efficiency
With high performance and low dynamic power consumption the Cortex-M3 processor delivers leading power efficiency 12.5 DMIPS/mW based on 90nmG. Coupled with integrated sleep modes and optional state retention capabilities the Cortex-M3 processor ensures there is no compromise for applications requiring low power and excellent performance.

Full featured
The processor executes ThumbŪ-2 instruction set for optimal performance and code size, including hardware division, single cycle multiply, and bit-field manipulation. The Cortex-M3 NVIC is highly configurable at design time to deliver up to 240 system interrupts with individual priorities, dynamic reprioritization and integrated system clock.

Rich connectivity
The combination of features and performance enables Cortex-M3 based devices to efficiently handle with multiple I/O channels and protocol standards such as USB OTG (On-The-Go).






The Cortex-M family is an ideal solution for ranges of compatible, easy to use embedded devices such as microcontrollers (MCU) where different cost, power and performance considerations must be made. Each processor delivers an optimal trade-off for a broad embedded application range.

Cortex-M family processors are all binary upwards compatible, enabling software reuse and a seamless progression from one Cortex-M processor to another.
