Overview

The STEVAL-IOD002V1
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
– 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
– CSP19 (2.5 x 2.5 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 L6364W is designed for full compliance with EMC immunity levels required by IEC 61131-9 (and IEC 60947-5-2 for surge
pulse). The STEVAL-IOD002V1
along the Arduino connectors may impact ESD and Burst immunity levels.

The digital section consists of the STM32 interface and the digital supply voltages to and from the
development board and the
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 L6364W. The converter also supplies the two
power dissipation, whose output voltage can supply the
