Stmicroelectronics releases Industrial Smart Sensor Evaluation suite

     Using a thin 45.8mm x 8.3mm motherboard as a highlight, STEVAL-IOD04KT1 Industrial sensor suite simplifies developers to develop compact IO-Link (IEC 61131-9) sensors for fieldbus-independent point-to-point bidirectional communication applications.

     This motherboard integrates STM32G0 microcontroller, L6364W IO Link transceiver, IIS2MDC high-precision 3-axis digital output magnetometer, and ISM330DHCX iNEMO inertial measurement module embedded with machine learning core. Thanks to the 2.5mm x 2.5mm CSP19 microchip package of the L6364W and the 2.3mm x 2.5mm WLCSP25 package of the STM32G0, the compact size of the board can use sensors with very small enclosures. The board is equipped with a 4-pin M8 industrial interface, which can be connected to any IO Link master controller that supports IO Link 1.1. The 10 pin expansion interface allows the board to connect more sensors of different modes.

     The accompanying STM32Cube software package STSW-IOD04K provides IO-Link Device Description (IODD) files, stmicroelectronics proprietary IO-Link demonstration software stack, and routines for managing L6364W and MEMS sensors. The package supports hot-swap activation, contains a library of functions that facilitate the development of various types of sensors, and the software architecture can be easily integrated with other X-CUBE software to further extend the functionality of the sensors.

     The L6364W transceiver reduces the workload of the STM32G0 because of its ability to handle IO-Link communication functions. The chip also implements IO-Link standard electrical interface and digital functions, including wake-up recognition, 15-byte data buffer and crystal free IO-Link clock extraction function. On-chip integration of safety features such as surge pulse protection, ESD protection, and reverse polarity protection up to ±2.5kV eliminates the need for the user to install additional devices and saves PCB space and bill of material costs. The L6364W integrates 3.3V and 5.0V LDO regulators on chip and digitally configurable step-down DC/DC converters to deliver load currents up to 50mA, helping developers meet the energy efficiency and EMC requirements of their applications.

     L6364W belongs to the stmicroelectronics IO-Link family of chip products. This product family provides a complete set of chip solutions that simplify IO-Link physical layer implementation, including the L6360 IO-Link control side transceiver and the L6362A and L6364Q IO-Link device chips.the STEVAL-IOD04KT1 suite contains all the tools needed to quickly connect sensors for evaluation and use, including IO-Link M8-M12 adapter cable and STLINK-V3MINI code burner from stmicroelectronics
