Discovering the STM32 microcontroller

... 2 Introduction to the STM32 F1 The STM32 F1xx micro-controllers are based upon the ARM Cortex- M3 core. The Cortex-M3 is also the basis for micro-controllers from a number of other manufacturers ... Architecture The STM32, illustrated in Figure 2.3 connects the three buses defined by the Cortex-M3 through a micro-controller level bus matrix. In the STM32, the ICode bu...
