STMicroelectronics STEVAL-SPIN3202

Overview

STEVAL-SPIN3202 from STMicroelectronics is an evaluation board for three-phase BLDC motor control, built around the STSPIN32F0A integrated controller with embedded STM32F0 MCU and STD140N6F7 60 V, 80 A N-channel MOSFETs in DPAK. It supports single-shunt current sensing, 7–45 V input, up to 15 A_RMS output, and runs sensored/sensorless 6-step and FOC firmware from X-CUBE-MCSDK-Y.

For engineers reviewing the STEVAL-SPIN3202 datasheet, STEVAL-SPIN3202 pinout, STEVAL-SPIN3202 application, or STEVAL-SPIN3202 equivalent, this board serves as a production-ready reference for low-voltage motor drive validation in home appliances, drones, power tools, and industrial fans - with integrated ST-LINK/V2-1, Hall/encoder inputs, and dual regulators (3.3 V buck + 12 V LDO).

Technical Context

The board implements a full three-phase inverter stage using six STD140N6F7 MOSFETs controlled by the STSPIN32F0A's gate drivers, which integrate bootstrap circuitry, dead-time insertion, and overcurrent protection via an internal comparator. The embedded STM32F0 MCU executes motor control algorithms and manages analog signal conditioning for single-shunt current sensing and bus voltage monitoring.

It provides digital Hall sensor and quadrature encoder interfaces, configurable BEMF sensing on GPIO pins, and supports both sensored commutation and sensorless FOC through pre-certified firmware in the STM32 Motor Control SDK. The onboard ST-LINK/V2-1 enables debugging, programming, and real-time parameter tuning without external tools.

FAQ

What firmware versions are supported on STEVAL-SPIN3202?

The board natively supports X-CUBE-MCSDK-Y firmware releases v6.0 and later, including both sensored 6-step and sensorless FOC implementations. Precompiled binaries and source code are provided via ST's official GitHub repository and are compatible with STM32CubeMX configuration.

Can STEVAL-SPIN3202 drive motors above 45 V?

No - the board's input stage and STSPIN32F0A controller are rated for maximum 45 V DC input. Exceeding this voltage risks permanent damage to the MOSFETs, gate drivers, and regulators. For higher-voltage applications, ST recommends STEVAL-SPIN3201 (100 V) or discrete gate driver + MCU solutions.

Does STEVAL-SPIN3202 support encoder feedback?

Yes - it features dedicated differential A/B/Z inputs compatible with industry-standard quadrature encoders, routed to STM32F0 GPIOs with hardware filtering. Encoder signals are processed in firmware for position/velocity closed-loop control in FOC mode.

Is external current sensing required for single-shunt operation?

No - the board integrates all necessary signal conditioning: shunt amplifier, offset trimming, and overcurrent comparator with programmable threshold. Only the motor phase currents and DC bus voltage need connection; no external op-amps or comparators are needed for basic operation.
