1. What is STM32 Motor Control Ecosystem?
From hardware tools and embedded software to training resources and documentation, the STM32 ecosystem offers many tools to ease the development of motor control applications. STM32 MCUs are particularly suitable to develop Permanent Magnet Synchronous Motors (PMSM), Brushless DC motors (BLDC) and Stepper motors.

4. STM32 compliant with Motor Control application
The STM32 portfolio includes devices based on Arm® Cortex®-M cores (M0, M0+, M3, M33, M4, and M7). Thanks to the MCUs' shared ecosystem, developers benefit from enhanced flexibility to move forward with their motor control design.
Each STM32 series offers a different set of peripherals matching different Motor Control application requirements.

|---|---|---|---|---|---|
| STM32G0xx | Cortex-M0+ | 64MHz | 16KB-512KB | + | 1x (128MHz) |
| STM32F303 | Cortex-M4 (DSP/FPU) | 72MHz | 32KB-512KB | ++++ | 3x (144 MHz) |
| STM32F302 | Cortex-M4 (DSP/FPU) | 72 MHz | 32KB-512KB | +++ | 1x (144 MHz) |
| STM32F301 | Cortex-M4 (DSP/FPU) | 72 MHz | 16KB-64KB | ++ | 1x (144 MHz) |
| STM32G431 | Cortex-M4 (DSP/FPU) | 170MHz | 32KB-128KB] | +++ | 2x (170 MHz) |
| STM32G474 | Cortex-M4 (DSP/FPU) | 170 MHz | 32KB-128KB | ++++ | 3x (170 MHz) |
| STM32F4xx | Cortex-M4 (DSP/FPU) | 180MHz | 256KB-1024KB | ++ | 2x (180 MHz) |
| STM32F7xx | Cortex-M7 | 216 MHz | 64KB-2048KB | ++ | 2x (216 MHz) |
| STM32H7xx | Cortex-M7 + M4 (option) | 480 MHz | 128KB-2018KB | ++ | 2x (240 MHz) |
The STM32G4 series combines a 32-bit Arm® Cortex®-M4 core (with FPU and DSP instructions) running at 170 MHz combined with three different hardware accelerators, rich analog peripherals and advanced motor control timers to meet all motor control application requirements. These product series are ideal for Motor Control applications.
The STSPIN32F0 is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes. This product series combines an STM32F031 microcontroller with triple half-bridge gate driver able to drive power MOSFETs or IGBTs with a current capability of 600 mA (sink and source) as well as other analog components.
