STM32F103VET6 is also compatible with open-source environments like PlatformIO and Arduino (with specific libraries).

What are the power consumption options in STM32F103VET6?

Sleep mode: The CPU is stopped, but peripherals continue to function.

Stop mode: The CPU and most of the peripherals are stopped to reduce power consumption.

Standby mode: The microcontroller consumes the lowest amount of power, with most functions disabled except for the RTC (Real-Time Clock) and external interrupts.

What is the maximum clock speed of STM32F103VET6?

The STM32F103VET6 operates at a maximum clock speed of 72 MHz, which is sufficient for many embedded applications requiring moderate performance.

Can STM32F103VET6 be used for real-time applications?

Yes, the STM32F103VET6 is well-suited for real-time applications. Its Cortex-M3 core offers deterministic performance, and the presence of multiple timers, interrupt handling, and low-power modes make it effective for time-critical systems, such as motor control, sensor readings, and communication tasks.
