STM32F103C8T6

The STM32F103xx performance line incorporates a high-performance 32-bit ARM Cortex-M3 RISC core operating at a frequency of up to 72 MHz, high-speed embedded memories (up to 128 KB of Flash memory and up to 20 KB of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

All devices feature two 12-bit ADCs, three general-purpose 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces, including up to two I2C and SPI interfaces, three USART interfaces, one USB interface, and one CAN interface.

The STM32F103xx performance line operates over a temperature range of -40°C to +105°C, with a supply voltage ranging from 2.0 V to 3.6 V. A complete set of low-power operating modes allows the design of energy-efficient applications.

Depending on the selected device, different sets of peripherals are included. The description below provides an overview of the complete range of peripherals available within this family.
