STMicroelectronics EVSPIN32G4-DUAL

Overview

EVSPIN32G4-DUAL from STMicroelectronics is a dual-motor evaluation board for three-phase BLDC control, integrating STSPIN32G4 (32-bit Arm Cortex-M4 MCU + gate driver) and STDRIVE101 triple half-bridge drivers, supporting 10 Arms per stage at 10–74 V bus, with single-shunt current sensing, Hall/encoder feedback inputs, and CAN FD interface via TCAN330D.

For engineers reviewing the EVSPIN32G4-DUAL datasheet, EVSPIN32G4-DUAL pinout, EVSPIN32G4-DUAL application, or EVSPIN32G4-DUAL equivalent, this board enables rapid validation of sensor-based and sensorless dual-motor control in compact industrial motion systems requiring integrated voltage regulation, thermal monitoring, and FDCAN communication.

Technical Context

The board implements two independent motor control channels, each combining STSPIN32G4's embedded STM32G431 (170 MHz, CORDIC, 128 KB flash, 32 KB SRAM) with STDRIVE101's 75 V, 600 mA gate drivers and dedicated protection circuitry including overcurrent comparators, UVLO, and thermal shutdown.

It supports simultaneous operation of two BLDC motors using either sensorless control (via internal op-amps for single-shunt sensing) or sensor-based algorithms (Hall, quadrature, or SSI absolute encoders), with bus voltage monitoring, NTC-based temperature sensing, and drain-source voltage sensing on all STL110N10F7 MOSFETs.

FAQ

What is the maximum peak current per motor channel?

The EVSPIN32G4-DUAL supports up to 17 A peak current per power stage, as specified in Table 1 of DB4741 Rev 2. This rating assumes short-duration pulses and adequate thermal management; continuous operation is limited to 10 Arms at 25 °C ambient with both stages active.

Does the board support sensorless FOC out of the box?

Yes - the STSPIN32G4 integrates two rail-to-rail op-amps and comparator blocks that enable single-shunt sensorless FOC implementation. The board includes all necessary signal conditioning and ADC routing (PA2, PA3, PC5, etc.) to run open-loop or closed-loop observer-based algorithms without external components.

Can both motors be controlled synchronously using one firmware instance?

Yes - the embedded STM32G431 MCU runs a single firmware image managing both motor control loops. Its dual advanced timers (TIM1/TIM8), 19-channel ADC, and flexible GPIO mapping allow time-synchronized PWM generation, current sampling, and encoder capture across both channels.

Is CAN FD functionality fully implemented and tested on this board?

Yes - the TCAN330D transceiver (U4) is soldered and routed with proper termination and shielding. FDCAN1_TX/RX signals are connected to the STM32G431's dedicated peripheral, and the board includes CANH/CANL headers (J15), shield ground, and 120 Ω termination jumpers for compliant bus integration.
