STEVAL-IHM015V1
Description
The STEVAL-IHM015V1 demonstration board is
a complete development platform for low voltage
motor control applications. Based on a cost
effective, flexible and open design, it allows easy
demonstration of the ST7MC2S4 capabilities to
drive low voltage synchronous motors.
The ST7MC2S4 is an 8-bit microcontroller with 16
Kb internal Flash memory.
The STEVAL-IHM015V1 features complete
hardware for developing motor control
applications based on ST7MC peripherals
including motor control peripherals (MTC), and
serial communication interface (SCI).
September 2008
The STEVAL-IHM015V1 uses an in-circuit
communication (ICC) standard interface to
connect to the host PC via in-circuit
debuggers/programmers such as the inDARTSTX board from Softec. The power stage of the
board is designed to support up to 25 A and up to
50 V. It is possible to use the STS8DNH3LL
devices included on the board, or replace them
with different devices in the SO-8 package (dual
or single devices for chip) or DPAK. Power supply
stages can be easily configured for a wide range
of bus voltages.
