I'm trying to control a PMSM electric machine using STM32.
I need to use ST Motor Control Workbench and here is compatible STM32 Microcontrollers :

the question is why STM32F103C8T6 is not compatible! what is the main difference between STM32F103RB and STM32F103C8? ( I know the number of pins is different. but is there any other reason that makes F103C8 not compatible?) Thanks!
