Overview

The X-NUCLEO-IOD02A1
transceiver, is designed to meet the electrical and communication protocol requirements with the IO-Link master.
The expansion board main features are:
• 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 V
– 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
• Equipped with Arduino UNO R3 connectors
• RoHS and WEEE compliant
Important: The L6364 is designed for full compliance with EMC immunity levels required by IEC 61131-9 (and IEC
60947-5-2 for surge pulse). The
purposes and the long net paths along the Arduino connectors may impact ESD and Burst immunity levels.

The on-board L1 inductor and C6 capacitor enable the step-down converter (active by default through SW4 by
closing 1-2) embedded in the L6364. The converter also supplies the two
dissipation, whose output voltage can supply the

The digital signal levels are set by the MCU on the
