STMicroelectronics L6364
L6364 - Dual channel transceiver IC for SIO and IO-Link sensor applications
The L6364 is a dual channel transceiver for industrial sensor applications. It has been designed to support the IO-Link standard and acts as a bridge between a microcontroller with a sensor or actuator function and a 24 V supply and signaling cable.
In normal operation the L6364 is configured by the microcontroller via the SPI interface at startup. Typically, the L6364 then operates as a Single Input Output IO-Link device driving the output lines as configured by the microcontroller. If the device is connected to an IO-Link master, then the master can initiate communication and exchange data with the microcontroller while the L6364 acts as a physical layer for the communication.

STDES-IOD002V1 - Dual channel IO-Link device reference design based on L6364Q and STM32L051
The STDES-IOD002V1 is a reference design board for a dual channel IO-Link device mounting the L6364Q transceiver, the STM32L051T8Y6TR microcontroller running STSW-IOD02L051, a 7-pin programming connector and a 10-pin expansion connector. The STDES-IOD002V1 compact size allows achieving high EMC immunity levels and makes the application suitable for the harsh industrial environments.
Thanks to a set of configurable drop jumpers and switches, combined with the source code of the STSW-IOD02L051, different configurations are possible.
The microcontroller can be programmed by a dedicated SWD 7-pin connector.
A 10-pin expansion connector allows the STDES-IOD002V1 to host external sensors with I2C control interface and up to two interrupts (e.g., IIS2MDC or ISM330DHCX).
The on-board push button is used to test the CQ line or to control the DIO line via the CTLD pin.

STEVAL-IOD002V1 - Dual channel IO-Link device expansion board based on L6364W for STM32 Nucleo
The STEVAL-IOD002V1 expansion board for STM32 Nucleo is based on the L6364W dual channel SIO and IO-Link PHY device transceiver embedding 50 mA 3.3 V and 5.0 V voltage regulators, DC-DC converter and M-sequence management. The expansion board provides an affordable and easy-to-use solution for the development of SIO and IO-Link industrial sensor applications, letting you easily evaluate the L6364W communication features and robustness.
The STEVAL-IOD002V1 communicates with the STM32 controller via SPI and GPIO pins and it is compatible with the Arduino UNO R3 (default configuration) and ST morpho (optional, not mounted) connectors (when connected to a NUCLEO-L073RZ or NUCLEO-G071RB development board).
Communication via IO-Link can be performed in either Multi-byte and Single-byte modes with SPI control of IC configuration and bidirectional sensor data transmission, or in Transparent mode with SPI control of IC configuration and UART interfacing for bidirectional sensor data transmission.
The switches on the STEVAL-IOD002V1 conveniently allow you to configure L6364W and expansion board settings such as transmission mode and DC-DC converter enable/disable according to application requirements.
You can also perform evaluation of comprehensive industrial sensor modules by connecting the STEVAL-IOD002V1 to the X-NUCLEO-IKS02A1 sensor shield.

STEVAL-IOD04KT1 - Industrial smart sensor kit based on L6364W dual IO-Link device transceiver
The STEVAL-IOD04KT1 is a reference design kit that exploits the features of the L6364W IO-Link dual-channel device transceiver.
The kit consists of the STEVAL-IOD004V1 main board (not available for sale), the STLINK-V3MINI programmer and debugger tool, a 14-pin flat cable, and an M8 to M12 standard industrial connector adapter.
The kit acts as a modern smart industrial sensor to be connected to a master IO-Link hub (or a suitable PLC interface).
The power supply for the MCU, sensors, and other logic devices derives from the DC-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 the L6364W transceiver and the MEMS industrial sensors.
The tiny dimensions of the main board have been achieved thanks to the small sizes of the CSP package options of L6364W and STM32G071EB.
Connect the main board to an IO-Link master via the adapter and the M8 connector included 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 a new firmware.
