The STM32F103xx medium-density performance line family incorporates the highperformance ARM® Cortex®-M3 32-bit RISC core operating at a 72 MHz frequency, highspeed 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.

STM32F103C8T6 Projects
- blue pill board based on STM32F103C8T6 board
For beginners it might be difficult to use the popular and cheap blue pill board based on
STM32F103C8T6. It’s because using an embedded development tools like KEIL isn’t easy for
beginners. This 32 bit microcontroller based on ARM Cortex-M3 architecture is far better than
your traditional arduino board. You can compare it to Arduino DUE but it has got a very small size like the arduino Nano. There’s lack of proper documentation on it and everything available in the internet is quite scattered. So, here’s something to get you started easily.
