A Comprehensive Introduction to STM32F103CBT6 Microcontroller [Video]

STMicroelectronics STM32 F1 Mainstream MCUs cover the needs of a large variety of applications in the industrial, medical, and consumer markets. With this series, ST has pioneered the world of ARM® Cortex™-M microcontrollers and set a milestone in the history of embedded applications. High performance with first-class peripherals and low-power, a low-voltage operation is paired with a high level of integration at accessible prices with a simple architecture and easy-to-use tools. These MCUs come with up to 72MHz CPU frequency, from 16Kbytes to 1Mbytes Flash, 4 to 80Kbytes of RAM, and a variety of embedded peripherals, such as USB, timers, USART, temperature sensor, ADC, and DAC to fit all your requirements.

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, a 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 modes 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.
