The STM32F405xx and STM32F407xx family is based on the high-performance ARM® Cortex®-M4 32-bit RISC core operating at a frequency of up to 168 MHz.
The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM single-precision data-processing instructions and data types.
It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.
The STM32F405xx and STM32F407xx family incorporates high-speed embedded memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers. a true random number generator (RNG).
They also feature standard and advanced communication interfaces.

به جرات میتوان گفت محبوب ترین میکروکنترلر ها در بین خانوادهARM سری STM32 است که دارای طیف مختلف از لحاظ سایز - کارایی و قیمت هستند.

این میکرو کنترلر ها در ایران محبوبیت زیادی پیدا کرده است و همچنین مشاهده شده جدید ترین سیستم ها با این میکرو کنترلر در صنعت ساخته شده و از لحاظ کارایی و مقاومت در برابر نویز بسیار عالی عمل کرده است و برنامه نویسان به سرعت از خانواده های قبلی به این خانواده مهاجرت کرده اند.

این ای سی از بخش های متفاوت TIMER,ADC,DAC,PWM,COUNTERو... تشکیل شده است که بسته به نیاز خود می توانید نمونه های مختلف را انتخاب کنید.

توصیه مااینست برای کار با این ای سی حتما از نرم افزار STM32CUBEMX(دانلود)  استفاده کنید که آموزش کار با ان به صورت تصویری توسط گروه آترین الک(کلیک کنید) تهیه شده است.
