reverse polarity– EMC and EMI tested according to standard requirements– RoHS compliant

Description

The STEVAL-IOD04KT1 is a reference design kit that exploits the features of theL6364W IO-Link dual-channel device transceiver.

The kit consists of the STEVAL-IOD004V1 main board (not available for sale), theSTLINK-V3MINI programmer and debugger tool, a 14-pin flat cable, and an M8 toM12 standard industrial connector adapter.

The kit acts as a modern smart industrial sensor to be connected to a master IO-Linkhub (or a suitable PLC interface).

The power supply for the MCU, sensors, and other logic devices derives from theDC-DC converter controller embedded in the L6364W.

The on-board STM32G071EB microcontroller runs an IO-Link demo stack v.1.1,which controls the IO-Link communication, and the software code that manages theL6364W transceiver and the MEMS industrial sensors.

Data brief

DB4571 - Rev 2 - December 2021For further information contact your local STMicroelectronics sales office.

www.st.com

The tiny dimensions of the main board have been achieved thanks to the small sizesof the CSP package options of L6364W and STM32G071EB.

Connect the main board to an IO-Link master via the adapter and the M8 connectorincluded in the kit for normal operation. Connect the same board to the STLINK-V3MINI through the flat cable only if you want to program the STM32G071EB with anew firmware.

1 Solution overview

This reference design targets IO-Link based applications, that is, smart industrial sensors that feature easyconfiguration, remote monitoring, reduced wiring, advanced diagnostics, and easy device replacement.The main board (STEVAL-IOD004V1) has been designed with few ICs. Taking this into consideration, smart-sensing applications can benefit from the L6364W dual-channel transceiver. For example, the ISM330DHCXinertial module can monitor a robotic arm (for vibration and compensation) while the IIS2MDC can detect themagnetic field, providing a warning along the supplementary channel.
