The STM32F20x family is based on the high-performance ARM® Cortex®-M3 32-bit RISC
core operating at a frequency of up to 120 MHz. The family incorporates high-speed
embedded memories (Flash memory up to 1 Mbyte, up to 128 Kbytes of system 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.
The devices also feature an adaptive real-time memory accelerator (ART Accelerator™)
that allows to achieve a performance equivalent to 0 wait state program execution from
Flash memory at a CPU frequency up to 120 MHz. This performance has been validated
using the CoreMark® benchmark.
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 number random generator (RNG). They also feature standard and advanced
communication interfaces. New advanced peripherals include an SDIO, an enhanced
flexible static memory control (FSMC) interface (for devices offered in packages of 100 pins
and more), and a camera interface for CMOS sensors. The devices also feature standard
peripherals.
• Up to three I2Cs
• Three SPIs, two I2Ss. To achieve audio class accuracy, the I2S peripherals can be
clocked via a dedicated internal audio PLL or via an external PLL to allow
synchronization.
• Four USARTs and two UARTs
• A USB OTG high-speed with full-speed capability (with the ULPI)
• A second USB OTG (full-speed)
• Two CANs
• An SDIO interface
• Ethernet and camera interface available on STM32F207xx devices only.
Note: The STM32F205xx and STM32F207xx devices operate in the –40 to +105 °C temperature
range from a 1.8 V to 3.6 V power supply. On devices in WLCSP64+2 package, if IRROFF
is set to VDD, the supply voltage can drop to 1.7 V when the device operates in the 0 to
70 °C temperature range using an external power supply supervisor (see Section 3.16).
A comprehensive set of power-saving modes allow the design of low-power applications.
STM32F205xx and STM32F207xx devices are offered in various packages ranging from 64
pins to 176 pins. The set of included peripherals changes with the device chosen.These
features make the STM32F205xx and STM32F207xx microcontroller family suitable for a
wide range of applications:
• Motor drive and application control
• Medical equipment
• Industrial applications: PLC, inverters, circuit breakers
• Printers, and scanners
• Alarm systems, video intercom, and HVAC
• Home audio appliances

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.
