STM32 MCUs Products

I'm working to make commercial smart switch for industrial applications, for that i designed using stm32f103c8t6 micro controller, but getting lead time of more than 52 weeks, please suggest MCU's alternative to this which are immediately available.

Route DMA interrupt signal to PWM timer trigger input

It's a STM32L053R8 (Nucleo64) and i am using a DAC with circular DMA to generate an analog waveform. Now i need to use a PWM timer to generate some digital output signals synchronous to the DMA cycle. Can i use two pins to route the DMA interrupt to ...

STM32H7 PWM ASYMMETRIC MODE

Hi, I would use PWM Asymmetric mode to create phase shift between two PWM signals on stm32h7. i didn't find application note for this mode for stm32cubemx, could anyone explain it for me please ? duty cycle must be the same for the two signals.Thank

Obtain a PWM with 3 outputs having 120 degress phase shift (STM32G070CB)

Hi,I need to obtain the attached behavior at the output pins with minimal MCU cycles.I also need interrupts at the beginning of each periods, because I need to do different stuff at each period.I'm using STM32G070CB which has 64MHz clock frequency an...
