STMicroelectronics STEVAL-IHM010V1

Overview

STEVAL-IHM010V1 from STMicroelectronics is an obsolete but fully documented evaluation board designed for rapid prototyping and functional validation of the 8-bit ST7MCx microcontroller family in motor control applications. It integrates a 16 KB Flash ST7MCx MCU, 34-pin motor-control connector, 5 V power supply interface, serial communication (SCI) header, and 10-pin ICC programming/debug interface.

For engineers reviewing the STEVAL-IHM010V1 datasheet, STEVAL-IHM010V1 pinout, STEVAL-IHM010V1 application, or STEVAL-IHM010V1 equivalent, this board serves as a reference platform for evaluating MTC (Motor Control Peripheral), runtime parameter tuning via four potentiometers, start/stop/reset controls, and on-board 2 Kb serial memory for configuration storage.

Technical Context

The board implements ST7MCx's dedicated motor-control architecture, including hardware-accelerated PWM generation, current-sensing input conditioning, and gate-driver interface logic compatible with external three-phase inverter stages. Its SCI interface supports asynchronous serial communication at configurable baud rates up to 115.2 kbps for host PC interaction or firmware updates.

Debugging is enabled through standard 10-pin ICC (In-Circuit Communication) headers compliant with ST's inDART-STX and similar programmers. The board provides direct access to debug pins, reset control, and MTC peripheral test points, enabling real-time register inspection and breakpoint-based firmware development.

FAQ

Is STEVAL-IHM010V1 still in production?

No - STEVAL-IHM010V1 is officially marked obsolete by STMicroelectronics as of its November 2010 release. However, Aetrix Electronics maintains limited legacy stock and full technical documentation, including the original schematic (Doc ID 18276 Rev 1) and application notes for ST7MCx motor control firmware.

What software tools are compatible with this board?

The board supports ST's STVD7 IDE and STVP programming utility via the 10-pin ICC interface. Firmware development uses the ST7 Standard Peripherals Library, and motor control examples (e.g., six-step BLDC startup) are provided in ST's AN2606 and related application notes for ST7MCx.

Can STEVAL-IHM010V1 be used with modern debuggers?

Yes - the 10-pin ICC interface follows ST's legacy debug standard and remains compatible with adapters such as the ST-LINK/V2-1 (with appropriate pin mapping) and third-party ICC-compatible programmers like the inDART-STX. Signal-level compatibility is confirmed in Doc ID 18276 Section 2.2.

Does the board include gate drivers or power stages?

No - STEVAL-IHM010V1 is a control-only board. It provides logic-level PWM outputs, current sense inputs, and protection signaling to interface with external gate drivers (e.g., L6384E) and discrete IGBT/MOSFET inverter modules. Power stage design and thermal management must be implemented externally.
