STMicroelectronics STEVAL-IFN001V2

Overview

STEVAL-IFN001V2 from STMicroelectronics is a low-cost two-layer starter development kit built around the ST10F276Z5 16-bit Flash microcontroller with integrated DSP capabilities, designed specifically for multi-axis motion control prototyping. It supports dual CAN bus interfaces, RS232/RS485 serial communication, I²C (3.3 V and 5 V), and features dedicated connectors for ST's powerSPIN motor driver evaluation boards (e.g., VN808/VN340) and MC-standard motor control interfaces.

For engineers reviewing the STEVAL-IFN001V2 datasheet, STEVAL-IFN001V2 pinout, STEVAL-IFN001V2 application, or STEVAL-IFN001V2 equivalent, this board serves as a validated hardware platform for evaluating real-time motor control algorithms, encoder-based position feedback, PWM-driven three-phase inverter staging, and industrial fieldbus integration in motion systems.

Technical Context

The board implements a complete motion control signal chain: six-channel complementary PWM outputs (PWM_1H/L through PWM_3H/L) drive external gate drivers or powerSPIN ICs; quadrature encoder inputs (ENCODER_A/B/INDEX) support high-resolution position sensing; and analog current/voltage monitoring channels (Phase_A/B/C, Bus Voltage, Heatsink Temperature, NTC bypass) feed into the ST10F276Z5's 16-channel 10-bit ADC. Dedicated fault signaling (Fault, Dissipative brake, Relay) enables safe torque shutdown.

Communication is segmented across isolated domains: dual CAN transceivers (L9616) support J1939 or CANopen stack development; ST202E RS232 and ST485A RS485 transceivers provide legacy industrial connectivity; and dual I²C buses (3.3 V and 5 V) interface with sensors or auxiliary peripherals. Power sequencing is managed via STLF33CDT (3.3 V) and STLF50CDT (5 V) LDOs, with +12 V rail available for external driver biasing.

FAQ

Does STEVAL-IFN001V2 include the ST10F276Z5 microcontroller pre-programmed with motion control firmware?

No. The board ships with the ST10F276Z5 microcontroller in blank Flash state. Users must load application firmware via the on-board JTAG/SWD debug interface using ST's STVD or STMStudio tools. Example motor control projects and HAL libraries are available in ST's official application notes AN2606 and AN2742.

Can STEVAL-IFN001V2 directly drive brushless DC (BLDC) or stepper motors without external power stages?

No. The board provides only logic-level PWM and control signals-not power switching. It requires connection to external motor driver stages such as ST's VN808 (integrated 3-phase driver) or discrete gate-driver + IGBT/MOSFET inverter modules via its powerSPIN or MC connectors.

What encoder types are supported by the ENCODER_A/B/INDEX inputs?

The inputs accept differential or single-ended 5 V TTL/CMOS quadrature encoder signals up to 10 MHz. Internal digital filters suppress noise; index pulse detection supports homing routines. No internal line receiver-external termination or LVDS-to-TTL conversion may be needed for long cable runs.

Is the CAN interface compliant with ISO 11898-2 physical layer standards?

Yes. Each CAN channel uses an L9616 transceiver rated for ±36 V common-mode range and 1 Mbps operation, meeting ISO 11898-2 requirements. Termination resistors (120 Ω) are provided on-board and configurable via jumpers J209 and J210 for proper bus impedance matching.
