Key Product Benefits
STM32F767- 216MHz MCU
This microcontroller with 216MHz Arm Cortex-M7 core has the performance and peripherals to simultaneously manage the high data processing requirements of the field-oriented control algorithm with real-time communication, along with servo drive actuation and digital input/output interfacing.
STDRIVE101 - BLDC motor controller
This IC ensures robust 3-phase BLDC motor control by including all the half-bridge gate drivers, its own linear supply regulator and monitoring and protection functions in a highly integrated chip, also allowing far more compact solution designs. The embedded STH270N8F7-2 Power MOSFET feature high drain source voltage for 48V operation at very high switching efficiency.
IPS160H - intelligent power switch
This intelligent power switch with 60V max rating up to 2.4A and integrated current, overtemperature, and load disconnection protection is ideal for robust driving of different industrial loads.
CLT03-2Q3 - current limiter
This input current limiter allows the node to receive 0-24V sensor and other digital input signals with the necessary robustness and compliance with surge standards to ensure appropriate protection on sensitive logic circuitry and components.
L7987L - monolithic switching regulator
This compact step-down monolithic switching regulator up to 2 A DC with adjustable output voltage and current limitation features light load efficiency and constant current protection for the specific application conditions.
LD39150DT33-R - ultra-low drop linear regulator
This fast ultra-low drop linear regulator delivers highly regulated voltage to the MCU and Ethernet network processor, offering low drop voltage, low noise, and ultra-low quiescent current for maximum standby efficiency.
- Real-time, multi-axial position control with FOC algorithm
- Multi-protocol real-time high-speed Ethernet connectivity with EtherCAT stack
- 700W power capability with low thermal dissipation
- Data processing MCU with signal processing peripherals
- 2-channel load driving output and protected sensor feedback input
- Compact form factor with high noise immunity
- Low voltage platform up to 48V operation
- Capability to drive any kind of load, capacitive, resistive, inductive

The STEVAL-ETH001V1 servo drive evaluation board is designed to address motor applications involving multi-axial position control of three phases PMSM motors, with FOC algorithm. The evaluation board embeds a motor control power stage, a digital actuation section, ERT communication, and a power management section.
- The motor control power stage hosts the STDRIVE101 half bridge gate driver, six STH270N8F7-2 power MOSFETs and conditioning circuitry.
- Real-time connectivity with NETX90 network controller (not ST IC) is able to support different protocols, including the EtherCAT stack.
- The digital actuation section hosts an industrial IO management section with CLT03-2Q3 (input) and IPS160H (output).
- The power management section is managed by L7987L, L7805CD2T-TR, and LD39150DT33-R devices.
- The STEVAL-ETH001V1 is equipped with two RJ45 connectors for daisy-chain connection and an RS485 interface for digital encoder or host connection powered by ST3485.
- For better noise immunity, the PCB is based on a 6-layer stack and an insulated track for supply line and ground. A quadrature encoder interface with index is present as well.
