 Hello and welcome to this presentation of the STM32-L4 ARM Core. STM32-L4 integrates a Cortex-M4 core from ARM in order to benefit from the powerful performance of the 32-bit processor's architecture and particularly of the high level of performance in low power consumption. Based on the ARM Cortex-M4 core, the STM32-L4 series combines the control performances of the Cortex-M3 core and the DSP capability of a single-cycle DSP Mac for data processing. In addition, the STM32-L4 embeds a single precision FPU. For more details, please refer to the ARM website in which you will find all the information about the core Cortex-M4.
