The STM32F103xx medium-density performance line family incorporates the high-performance ARM®Cortex®-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
All devices offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN.
The devices operate from a 2.0 to 3.6 V power supply.
They are available in both the –40 to +85 °C temperature range and the –40 to +105 °C extended temperature range.
A comprehensive set of power-saving mode allows the design of low-power applications. The STM32F103xx medium-density performance line family includes devices in six different package types: from 36 pins to 100 pins.
Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this family.
These features make the STM32F103xx medium-density performance line microcontroller family suitable for a wide range of applications such as motor drives, application control, medical and handheld equipment, PC and gaming peripherals, GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs.

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.
