Product details
Overview
STEVAL-IHM041V1 from STMicroelectronics is an evaluation board for the STM8S103F3 8-bit microcontroller, designed to demonstrate motor control using a single-shunt inverter topology with space-vector PWM (SVPWM) and real-time current reconstruction. It integrates the STM8S103F3 MCU (16 MHz core, 8 KB Flash, 10-bit ADC, UART/SPI/I²C), dual-channel gate driver (STGIPN3H60), and 600 V/3 A IGBT power stage, targeting brushless DC (BLDC) motor control in appliances and small industrial drives.
For engineers reviewing the STEVAL-IHM041V1 datasheet, STEVAL-IHM041V1 pinout, STEVAL-IHM041V1 application, or STEVAL-IHM041V1 equivalent, this page delivers verified hardware architecture, validated SVPWM timing behavior, confirmed gate driver interface mapping, and documented BLDC commutation firmware support - all specific to the STM8S103F3-based inverter reference design.
Technical Context
The board implements a sensorless BLDC control loop using the STM8S103F3's advanced control timer (TIM1) for precise 3-phase SVPWM generation with dead-time insertion, synchronized to ADC sampling of reconstructed phase currents via a single shunt resistor. The STGIPN3H60 intelligent power module provides integrated gate driving, overcurrent protection, and thermal shutdown, interfaced directly to TIM1 complementary outputs and MCU GPIOs.
Real-time current reconstruction relies on the MCU's 10-bit ADC with scan mode and analog watchdog, sampling at up to 1 MSps during PWM off-times, while the UART interface enables parameter tuning and debug telemetry. Firmware is preloaded and compatible with ST's X-NUCLEO-IHM03A1 expansion board for extended development.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core MCU | STM8S103F3, 16 MHz STM8 core with 3-stage pipeline and Harvard architecture - enables deterministic 10 µs interrupt latency for critical motor control tasks. |
| Flash / EEPROM | 8 KB Flash (20-year data retention at 55 °C), 640 B true data EEPROM (300 kcycle endurance) - supports field-updatable motor control algorithms and calibration storage. |
| ADC | 10-bit ±1 LSB ADC with 5 multiplexed channels, scan mode, and analog watchdog - captures reconstructed phase currents with <±0.5% full-scale error at 3.3 V supply. |
| PWM Timing | TIM1 16-bit advanced timer with 4 CAPCOM channels, 3 complementary outputs, and programmable dead-time insertion - generates synchronized 3-phase SVPWM with <50 ns resolution and hardware fault blanking. |
| Power Stage | STGIPN3H60 intelligent power module: 600 V/3 A IGBTs, integrated bootstrap diodes, overcurrent/thermal protection, and 5 V logic supply - eliminates external gate drive components and reduces PCB footprint by 40%. |
| Communication | UART with clock output (LIN master, SmartCard, IrDA support), SPI up to 8 Mbit/s, I²C up to 400 kbit/s - enables real-time parameter tuning, firmware updates, and host controller integration. |
| Supply Range | 2.95–5.5 V operating voltage with flexible clock sources (16 MHz RC, 128 kHz RC, crystal, external clock) - supports direct connection to 3.3 V or 5 V system rails without level shifting. |

FAQ
What firmware is preloaded on the STEVAL-IHM041V1?
The board ships with fully functional sensorless BLDC motor control firmware implementing space-vector PWM, real-time current reconstruction, and startup sequence handling. Source code and configuration tools are provided in STSW-STM8020 software package, supporting modification via STVD or Cosmic C compiler.
Does STEVAL-IHM041V1 support Hall-effect or encoder feedback?
No - the board is specifically designed for sensorless operation using back-EMF zero-crossing detection and single-shunt current reconstruction. It lacks physical connectors or circuitry for Hall sensors or quadrature encoders; adding them would require custom PCB modifications and firmware rework.
Can the STGIPN3H60 power stage be replaced with discrete IGBTs or MOSFETs?
The board layout and gate driver interface are optimized exclusively for the STGIPN3H60 IPM. Replacing it with discrete devices would require redesigning the gate drive circuit, current sensing network, and thermal management - no alternative power stage footprint or routing is supported on this revision.
Is USB connectivity included on STEVAL-IHM041V1?
No - communication is provided only via UART through a standard 3.3 V TTL-level header (J1). USB-to-UART conversion requires an external adapter (e.g., ST-LINK/V2-1 or third-party CP2102 module); no onboard USB transceiver or connector is present.
