STMicroelectronics Unveils EVSPIN32G4-DUAL: Accelerating Product Development in Industrial and Consumer Sectors

(IN BRIEF) STMicroelectronics introduces the EVSPIN32G4-DUAL demonstration board, featuring the highly integrated STSPIN32G4 motor controller, which facilitates the control of two motors simultaneously, streamlining product development processes and simplifying PCB design. With its Arm Cortex-M4 MCU, the controller executes complex algorithms like field-oriented control (FOC) in real-time, catering to applications in robotics, factory automation, garden equipment, and power tools. Leveraging advanced gate drivers and power management circuitry, the board enables efficient motor control with safety features, while being supported by the extensive STM32 ecosystem, providing comprehensive tools and software examples for application development. The EVSPIN32G4-DUAL is now available for purchase at $145 from and distributors.

(PRESS RELEASE) GENEVA, 23-May-2024— /EuropaWire/ — STMicroelectronics’ EVSPIN32G4-DUAL demonstration board controls two motors from a single STSPIN32G4 integrated driver, accelerating product development and simplifying the PCB design and bill of materials.

The EVSPIN32G4-DUAL board cuts the time to market for advanced industrial and consumer products such as robots, multi-axis factory automation systems, garden equipment, and power tools. The STSPIN32G4 motor controller contains an Arm® Cortex®-M4 microcontroller (MCU) with the processing power to manage both motors simultaneously, executing complex algorithms like field-oriented control (FOC) in real-time. In addition, MCU peripherals support sensored or sensorless FOC and advanced position and torque-control algorithms, including motor-control and general-purpose timers, analog functions including operational amplifiers and comparators.

The EVSPIN32G4-DUAL demonstration board leverages an advanced three-phase gate driver integrated in the STSPIN32G4 and an additional STDRIVE101 gate driver to control two three-phase inverters delivering up to 10A with a maximum supply voltage of 74V. Both gate drivers have their own bootstrap circuitry and safety features including drain-source voltage monitoring, cross-conduction prevention, several thermal protection mechanisms, and under-voltage lockout (UVLO).

EVSPIN32G4-DUAL also leverages the STSPIN32G4’s built-in power-management circuitry, permitting a compact design with a low BOM that is easy to procure and permits rapid assembly in production. The power management includes a programmable buck converter for gate drivers VCC supply, a low-dropout linear regulator, and a special regulator with low quiescent current to supply the MCU during standby.

The STSPIN32G4 is included in the STM32 ecosystem that provides extensive support for application development, including tools for starting the project, middleware packs, and software examples. The X-CUBE-MCSDK (motor control software development kit) has firmware libraries for algorithms including FOC and STM32 motor-control workbench. This is an easy-to-use graphical tool that lets the user select and automatically configure the EVSPIN32G4-DUAL directly from a menu.

EVSPIN32G4-DUAL is available now from and distributors, for $145.
