STMicroelectronics STSPIN32F0 - 32-bit MCU based motor driver IC
New STSPIN motor driver IC integrates an advanced BLDC controller and a 32-bit MCU in a 7x7 mm footprint
Smart Industry or Industry 4.0, often referred to as the fourth industrial revolution, is bringing more intelligence into everything and motor control is no exception: distributed intelligence, decentralized diagnostics, communication and flexibility to adapt in real-time to external events are a must, not forgetting the relentless pursuit of energy efficiency. ST squeezes all these capabilities, together with its expertise in motor control and embedded processing, in a new 7x7 mm STSPIN motor driver IC. With STSPIN32F0, the fourth industrial revolution arrives in motor control!
