The STM32F103CBT6 is a mainstream performance line microcontroller developed by STMicroelectronics, featuring an ARM Cortex-M3 core with 128 Kbytes of Flash memory, a 72 MHz CPU, motor control capabilities, USB, and CAN. Here is an overview of its key specifications and features:

– Processor: It is equipped with an ARM Cortex-M3 core that operates at a maximum frequency of 72 MHz, providing a performance of 1.25 DMIPS/MHz (Dhrystone 2.1) at 0 wait state memory access, with single-cycle multiplication and hardware division.
– Memory: The microcontroller includes 128 Kbytes of Flash memory and 20 Kbytes of SRAM.
– Clock, Reset, and Supply Management: It operates with a supply and I/O voltage range of 2.0 to 3.6 V, featuring power-on reset (POR), programmable delayed reset (PDR), and programmable voltage detector (PVD). It also includes a 4-to-16 MHz crystal oscillator, an internal 8 MHz factory-trimmed RC oscillator, an internal 40 kHz RC oscillator, and a phase-locked loop (PLL) for CPU clock, as well as a 32 kHz oscillator for the RTC with calibration.
– Low-Power Modes: The STM32F103CBT6 offers sleep, stop, and standby modes, with a VBAT supply for RTC and backup registers.
– ADC Converters: It features two 12-bit, 1 µs A/D converters with up to 16 channels, a conversion range of 0 to 3.6 V, dual-sample and hold capability, and a temperature sensor.
– DMA: A 7-channel DMA controller is supported, with peripherals including timers, ADC, SPIs, I2Cs, and USARTs.
– I/O Ports: Up to 80 fast I/O ports are available, with 26/37/51/80 I/Os mappable on 16 external interrupt vectors, and almost all are 5 V-tolerant.
– Debug Mode: The microcontroller supports serial wire debug (SWD) and JTAG interfaces.
– Timers: It includes seven timers, three 16-bit timers with up to 4 IC/OC/PWM or pulse counter and quadrature (incremental) encoder input, a 16-bit motor control PWM timer with dead-time generation and emergency stop, and two watchdog timers (independent and window), as well as a SysTick timer 24-bit downcounter.
– Communication Interfaces: The STM32F103CBT6 offers up to nine communication interfaces, including up to two I2C interfaces (SMBus/PMBus), up to three USARTs (ISO 7816 interface, LIN, IrDA capability, modem control), up to two SPIs (18 Mbit/s), a CAN interface (2.0B Active), and a USB 2.0 full-speed interface.
– CRC Calculation Unit and Unique ID: It includes a CRC calculation unit and a 96-bit unique ID.
– Packages: The microcontroller is available in ECOPACK® packaging.

The STM32F103CBT6 is widely used in various applications such as embedded systems, motor control, smart home devices, wearable technology, and industrial automation, thanks to its high performance, low power consumption, and extensive connectivity options.
