L6364
The
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, a supply (up
to 32 V), and a signaling cable.
In normal operation, the microcontroller configures the
via the SPI interface at start-up. Thus, the
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
acts as a physical layer for the communication.
The main features are:
•
supply voltage from 5 to 35 V
•
low dissipative (5 Ω) CQ and DIO output stages configurable in high-side, low-side, push/pull
•
configurable (0.11 to 0.25 A) current limitation threshold of CQ and DIO lines
•
configurable (0.22 to 0.5 A) current limitation threshold of CQ/DIO line (join mode)
•
full protections:
–
embedded reverse polarization diode (D
OUT
pin)
–
full zero current reverse polarity between V
plus
, CQ, DIO, and PGND pins
–
configurable (up to 216°C) thermal shutdown threshold
–
7-bit, calibrated, temperature measurement
–
configurable (6.0 to 15 V) V
plus
undervoltage detection
–
CQ and DIO short-circuit current limit and reporting
•
-40 to +150°C operating temperature
•
suitable to drive L, C, and R loads
•
integrated UART peripheral with M-sequence handling (including checksum) for all IO-Link sequences
according to specification v1.1
•
single octet UART mode for unlimited M-sequence size and continuous data transfer
•
designed to meet the following application requirements:
–
ESD IEC 61000-4-2 protection to 4 kV
–
EMC surge protection 2A/50 μs (coupling 500 Ω)
•
QFN-20L 4x4 mm and CSP 2.5x2.5 mm (used for the design of STEVAL-IOD004V1) packages available
•
internal DC-DC buck converter controller with two internal MOS switches. A configurable switching
frequency buck converter can be obtained with an external capacitor and an inductor. The device also
includes linear regulators, which can optionally be used.
1.3.3
ISM330DHCX
The
is a system-in-package featuring a high-performance 3D digital accelerometer and 3D digital
gyroscope tailored for Industry 4.0 applications.
The various sensing elements have been manufactured using specialized micro-machining processes, while the
IC interfaces have been developed using CMOS technology that allows the design of a dedicated circuit trimmed
to match better the characteristics of the sensing element.
In the
, the sensing elements of the accelerometer and of the gyroscope are implemented on the
same silicon die, thus guaranteeing superior stability and robustness.
The
has a full-scale acceleration range of ±2/±4/±8/±16 g and a wide angular rate range of
±125/±250/±500/±1000/±2000/±4000 dps, permitting its usage in a broad range of applications.
All the design aspects and the calibration of the
have been optimized to reach superior accuracy,
stability, extremely low noise and full data synchronization.
An unmatched set of embedded features (machine learning core, programmable FSM, FIFO, sensor hub, event
decoding and interrupts) enables the implementation of smart and complex sensor nodes for high performance at
very low power.

IIS2MDC
The
is a high-accuracy, ultra-low-power 3-axis digital magnetic sensor, with a magnetic field dynamic
range of up to ±50 gauss.
