Intelligent Motor Control Chip Powers Smart Industry


For designers of smart industry and high-end consumer electronics, STMicroelectronics unveiled a compact single chip for intelligent motor control, which it claims offers the power and flexibility of a microcontroller-based drive by combining a MCU and an analog chip in a tiny 7 x 7 mm QFN package.

Target applications of the STSPIN32F0 include smart-manufacturing equipment, power tools and cooling fans, as well as emerging high-tech product categories such as drones, small robots, and home appliances containing high-efficiency motors, such as high-performance portable vacuum cleaners or air purifiers.

“Designers of Industry 4.0 and high-end consumer electronics systems need freedom to optimize their motor-control strategy, as well as high processing performance to enable autonomous operation with minimal intervention from a central controller,” explained Domenico Arrigo, General Manager, Industrial and Power Conversion Division, STMicroelectronics. “The STSPIN32F0 makes these qualities accessible in a convenient and space-efficient system-in-package, taking advantage of the power-control libraries and algorithms available from our uniquely rich STM32 ecosystem to streamline and simplify the development of intelligent and highly-featured precision motion controls.”

The STM32F0 MCU inside the STSPIN32F0 features the ARM Cortex-M0 core, which is capable of hosting versatile motor-control algorithms such as sensored or sensorless FOC, six-step control, and others.


The new STSPIN32F0 simplifies design leveraging the extensive STM32 development ecosystem, with software tools, firmware libraries and middleware available on top of the popular motion-control algorithms such as Field-Oriented Control (FOC) and 6-step control to streamline firmware development.

The MCU offers high performance for fast algorithm-execution times, needed for precision control of torque and speed up to high rpm, with bandwidth and headroom to support additional functionality, the firm says.

Analog Devices Announces New Industrial Automation Solutions

The STSPIN32F0 motor-control system-in-package is in production now in 7mm x 7mm QFN, priced from $1.95 for orders of 1000 pieces.
