Product overview


The STEVAL-IDP004V1 evaluation board with STM32 microcontroller has four separate L6360 ICs.

Communication with the ICs is via I²C in master mode and is managed by the STM32F205RB MCU; each L6360 has its own address and shares the bus with the other devices.

The STEVAL-IDP004V1 is developed to create a multi-port master d based on serial asynchronous communication to support the IO-Link protocol. Each node is equipped with an industrial M12 connector (as required by the standard) for connection with a single slave node using a cable 20 meter long; the wire is a normal three-pole: one for the IO-Link bus, one for the L+ line (positive supply voltage pole) and one for the L- line (negative supply voltage pole).

Beyond the IO-Link connection, the board includes RS-485 bus, CAN bus and USB hardware interfaces.

The layout is designed to meet the requirements for IEC61000-4-2/4/5 for industrial segment.
