Description
The STEVAL-IHM042V1 evaluation board is
designed as a complete dual motor field-oriented
control (FOC) demonstration platform featuring
STMicroelectronics’ ARM Cortex™-M4F 32-bit
core-based STM32F303CC microcontroller with
floating point support and two fully integrated
DMOS L6230 3-phase motor drivers.
It is designed as an integrated evaluation
environment for motor control applications in the
range of 8 V - 48 V DC bus voltage (extendable
up to 52 V) and nominal power up to 10 W for
each motor drive. The design exploits the
computational power of the STM32F303CC
microcontroller with 48 KB of internal SRAM and
256 KB Flash, 4 ADCs, 2 DACs, 7 comparators, 4
operational amplifiers with programmable gains,
SWD debugging, as well as the L6230 DMOS
driver’s 2.8 A output peak current, non-dissipative
overcurrent detection/protection, cross-
conduction protection, uncommitted comparator,
thermal shutdown, and undervoltage lockout.
The STEVAL-IHM042V1 is equipped with a USB-
to-serial interface, specifically for real-time data
exchange implemented by an STM32F103C8
pre-programmed with the STM32 Virtual COM
Port firmware.
The ST Link in-circuit debugger and programmer
is embedded in the board, allowing the user to
program and debug the STM32F303CC
microcontroller directly with a USB cable using a
compatible toolset.
