Product details

Overview

STM8/128-MCKIT from STMicroelectronics is a motor control starter kit built around the STM8S128 microcontroller, enabling immediate evaluation of scalar (V/f) and sensorless BLDC/ACIM motor control. It includes a three-phase inverter board, pre-flashed firmware, Hall sensor/tachometer interface support, and a bundled BLDC motor - all configured for out-of-box sensorless speed control operation.

For engineers reviewing the STM8/128-MCKIT datasheet, STM8/128-MCKIT pinout, STM8/128-MCKIT application, or STM8/128-MCKIT equivalent, this kit serves as a validated hardware-software reference for rapid prototyping of industrial fan, pump, and appliance motor drives using ST's STM8 motor control libraries and third-party C toolchains.

Technical Context

The kit implements scalar (V/f) control and sensorless field-oriented control (FOC) algorithms via the STM8S128 MCU's dedicated motor control peripherals - including 3-channel complementary PWM with dead-time insertion, ADC for current sensing, and timer-based Hall event capture. Firmware supports both open-loop and closed-loop speed regulation.

Hardware integrates a 3-phase IGBT/MOSFET inverter stage rated for 24–48 V DC bus, gate drivers with fault protection, current-sense amplifiers, and configurable position/speed feedback interfaces (Hall sensors or analog tachometer), enabling direct evaluation of AC induction and permanent magnet motor control topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
Core MCU	STM8S128, 16 MHz max CPU clock, 128 KB Flash, 6 KB RAM - provides sufficient code space and real-time ISR latency for dual-loop motor control.
Inverter Topology	Three-phase 6-switch IGBT/MOSFET bridge - supports BLDC and ACIM drive with configurable switching frequency up to 20 kHz.
PWM Capability	3 complementary PWM channels with programmable dead time (0–1023 ns) - ensures safe commutation and prevents shoot-through in inverter stage.
Feedback Interface	Hall sensor inputs (3x digital) + analog tachometer input - enables position-based or speed-only closed-loop control without encoder.
Motor Support	Pre-configured for 3-phase BLDC (bundled motor); reprogrammable for AC induction motors - allows validation across two major motor types with same hardware.
Power Input	24–48 V DC supply - matches common industrial low-voltage motor drive rails and avoids external step-down conversion.

FAQ

Is STM8/128-MCKIT compatible with modern IDEs and compilers?

Yes - the kit ships with ST's STM8 Motor Control Library (v2.x) and supports integration with third-party C toolchains including Cosmic, IAR Embedded Workbench, and SDCC. Source code is provided for full customization of control loops, PWM timing, and feedback processing.

Can the kit drive AC induction motors out of the box?

No - it boots into sensorless BLDC speed control mode with the included motor. Driving an AC induction motor requires reprogramming the STM8S128 with open-loop V/f or slip-compensated scalar control firmware, which is supported by the included software libraries and application notes.

Does STM8/128-MCKIT include current sensing capability?

Yes - the inverter board integrates dual shunt-resistor current sensing with op-amp conditioning and connects to the STM8S128's 10-bit ADC. This enables real-time phase current measurement for overcurrent protection and torque estimation in sensorless FOC implementations.

What debug interface does the kit use?

The kit uses ST-LINK/V2 (SWIM interface) for programming and real-time debugging of the STM8S128 MCU. The SWIM header is accessible via a standard 4-pin connector, supporting full breakpoint, register, and memory inspection without requiring additional adapters.
