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).

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.
