STMicroelectronics STEVAL-TTM002V1

Overview

STEVAL-TTM002V1 from STMicroelectronics is a standalone automotive motor control evaluation board built around the SPC560P50L3 32-bit Power Architecture MCU, featuring integrated FlexPWM timers with ADC synchronization, 10-bit ADCs, and hardware support for sensored/sensorless FOC algorithms. It provides a standardized 34-pin motor control interface, RS232 and CAN DB9 connectors, Hall/encoder sensor inputs, and SPI-configurable gate driver support - designed for BLDC motor control validation in chassis and safety-critical automotive systems.

For engineers reviewing the STEVAL-TTM002V1 datasheet, STEVAL-TTM002V1 pinout, STEVAL-TTM002V1 application, or STEVAL-TTM002V1 equivalent, this board serves as a complete reference platform for rapid prototyping of automotive-grade motor control firmware using ST's SPC5 Studio IDE and motor control library, with direct compatibility to the STEVAL-TTM001V1 low-voltage kit and third-party power stages.

Technical Context

The board implements a full-featured control stage centered on the SPC560P50L3 MCU, which integrates dedicated peripherals including three independent FlexPWM modules (supporting complementary/independent outputs), dual 10-bit ADCs with hardware-triggered sampling synchronized to PWM edges, and LIN/CAN transceivers compliant with ISO 11898-2 and ISO 17987-2. These enable precise current sensing, real-time BEMF detection, and closed-loop field-oriented control.

Power management includes on-board +3.3 V and +5 V regulation from 12–48 V DC input, ESD protection on all I/O lines (ESDLIN1524BJ), ferrite-bead filtered analog/digital domains, and isolated temperature/current monitoring circuits. The 34-pin motor control connector routes high-current phase signals, gate drive enables, brake inputs, and auxiliary feedback channels with defined signal integrity constraints.

FAQ

Does STEVAL-TTM002V1 include a power stage or only the control board?

No, STEVAL-TTM002V1 is a control-only board without integrated power MOSFETs or gate drivers. It connects to external motor drives via its 34-pin motor control interface and provides all necessary control signals, feedback acquisition, and protection logic - enabling flexible pairing with discrete or module-based power stages.

What software tools are required to develop firmware for this board?

Firmware development requires ST's SPC5 Studio IDE (free download), SPC5 Calibration Toolkit, and the ST Motor Control SDK v5.x or later. The board supports debugging via the included 14-pin JTAG connector compatible with the SPC5-UDESTK debugger, and firmware can be flashed over CAN, UART, or JTAG.

Is the CAN interface galvanically isolated?

No, the CAN transceiver (ST3232EBDR-based circuit) on STEVAL-TTM002V1 is not galvanically isolated. It complies with ISO 11898-2 for high-speed CAN but shares ground with the MCU domain. For isolated operation, external isolated CAN transceivers must be added between the DB9 connector and the board's CAN0_TXD/CAN0_RXD signals.

Can this board be used for PMSM motor control beyond BLDC?

Yes - the SPC560P50L3 MCU and board hardware fully support both trapezoidal (BLDC) and sinusoidal (PMSM) commutation. ST's motor control library includes sensorless FOC algorithms validated for PMSM, and the analog front-end (differential current sensing, BEMF capture, encoder/Hall inputs) meets requirements for high-bandwidth PMSM position estimation.
