Control board for automotive applications - STEVAL-TTM007A
Introduction
The
STEVAL-TTM007A
control board features the advanced Stellar E automotive-grade microcontroller SR5 E1 E7 (Stellar E
32-bit Arm® Cortex®-M7 automotive MCU 2x cores) with functional safety performance (ASIL-D capability). The dedicated
peripheral designed for motor control renders it possible to develop and implement firmware architectures driving up to two
independent motors. The latest motor control connector facilitates compatibility with the STEVAL-APD03ACB and STEVAL-
APD04ACB driving boards from the dedicated electric traction kit capable of driving all the ACEPACK DRIVE product family
based on the latest SiC MOSFET technology. The CAN, UART, and programmer connectors offer several interfaces with the
MCU. The dedicated software tool
StellarStudio
for the Stellar E microcontroller family can be used to configure the STEVAL-
TTM007A for each application with a user-friendly GUI.
The integrated
SPSB100
AEC-Q100-qualified power management integrated circuit (PMIC) ensures appropriate power supply
to the microcontroller and connectivity from the low voltage battery level.
