Features• Based on the L6364Q IO-Link device dual transceiver in QFN package with the

following main characteristics:– 2-channel (CQ and DIO) IO-Link PHY layer– IO-Link DLL (M-sequence handler and checksum)– Wake-up detection– Interrupt diagnostic pin– SPI and UART interfaces– 50 mA 3.3 V and 5.0 V linear regulators– 50 mA adjustable (5.0 ÷ 10.8 V) buck converter– Overload protection with adjustable intervention threshold– Overheating protection with adjustable shutdown threshold– Full reverse polarity on process side– Ground and VCC wire break protections– QFN-20L (4 x 4 x 0.9 mm) package

• 5 to 35 V operating voltage range• Red LED and green LED for status diagnostics• Radiated Emissions (EM Fields 30 MHz-1 GHz) < 40dB µV/m• Immunity to conducted disturbance (150 kHz-80 MHz) ≤ 10 V• Immunity to RF EM Fields (80 MHz-1 GHz) ≤ 10 V/m• Immunity to RF EM Fields (1 GHz-2.7 GHz) ≤ 3 V/m• Immunity to SURGE pulse (500 Ohm coupling) ≤ ± 1.2 kV• Immunity to ESD contact/air ≤ ±3 kV• Immunity to BURST noise ≤ ±1 kV• Compatible with STM32 Nucleo development boards• Equipped with Arduino UNO R3 connectors• RoHS and WEEE compliant

DescriptionThe X-NUCLEO-IOD02A1 expansion board for STM32 Nucleo is based on theL6364Q dual channel SIO and IO-Link PHY device transceiver embedding 50 mA 3.3V 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 thedevelopment of SIO and IO-Link industrial sensor applications, letting you easilyevaluate the L6364Q communication features and robustness.

The X-NUCLEO-IOD02A1 communicates with the STM32 controller via SPI andGPIO pins and it is compatible with the Arduino UNO R3 (default configuration) andST 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-bytemodes with SPI control of IC configuration and bidirectional sensor datatransmission, or in Transparent mode with SPI control of IC configuration and UARTinterfacing for bidirectional sensor data transmission.
