STMicroelectronics is one of the world's leading semiconductor supplier of technology provided by automation and robotics, so that other industry sectors provide greater security products, which is what we call intelligence industry. With the current developments, often called the "fourth industrial revolution", it is widely used by a variety of products (including STMicroelectronics MCU, motor control) so that industrial system becomes more intelligent, protective equipment and wireless module and and LED display controllers. The next is to introduce a suitable for use in avionics microcontroller (MCU).
STM32F4 series of high-performance ARM® Cortex® DSP and MCU and FPU instruction based on the accelerator and ART techniques NVM ™ -M4-STM32F4 series MCU using ST reaches the industry's highest test score based on a microcontroller with Cortex-M up 225DMIPS / 608CoreMark up to 180MHz operating frequency of execution from flash memory.
