ST X-NUCLEO-OUT16A1 User manual

Introduction
The X-NUCLEO-OUT16A1 industrial digital output expansion board, for STM32Nucleo, provides a powerful and flexible
environment for the evaluation of the driving and diagnostic capabilities of the IPS8200HQ octal high-side smart power solid
state relay, in a digital output module connected to 0.7 A industrial loads.
The X-NUCLEO-OUT16A1 interfaces with the microcontroller on the STM32 Nucleo via STISO620 and STISO621 and
Arduino® R3 connectors. The user can select which driving mode controls the IPS8200HQ: Parallel (SEL2 = L by JP21 = open)
or SPI (SEL2 = H by JP21 = closed). In the case of SPI selection, the user can select the communication protocol between 8
bits (SEL1 = L by JP22 = open) or 16 bits (SEL1 = H by JP22 = closed).
The VCC supply pin of the IPS8200HQ is provided by the connector CN1, while the loads (driven by the eight output channels of
the IPS8200HQ) can be connected between the connectors CN2, CN3, CN4, CN12, and the pin 2 of the connector CN1.
The on-board digital isolators (STISO620 and STISO621) feature the 2.8k VRMS (4k VPK) galvanic isolation between the two
application sides: Logic and process sides.
Logic side is the application side of the MCU and it is supplied by the VISO_L rail (3.3 V or 5.0 V). VISO_L can be supplied by
an external power supply connected to CN13 or, alternatively by the pin 4 (SW1 = close 1-2) or pin 5 (SW1 = close 2-3) of CN6.
The process side is the application side of the industrial loads and it is supplied by the VCC and VISO_P rails. The VISO_P (3.3
or 5.0 V) is usually supplied by the VREG rail (JP31 = closed) that can be generated by the step-down embedded in the
IPS8200HQ (SW17 = close 1-2, JP20 = closed, JP15 = closed and JP28 = close 2-4 (VREG = 3.3 V) or JP28 = 1-3 (VREG =
5.0 V)). Alternatively, VREG can be provided by an external power supply connected to CN14 (SW17 = close 2-3, JP20 = open,
JP15 = open).
In parallel driving mode (active with the default jumper and switch settings) the application board can work even without any
Nucleo board: in this case, the user must provide the process side voltage (usually 24 V) by the CN1 and the VISO_L (usually
3.3 V) by the CN13. The INX signals, available on CN5[1, 2, 3], CN8[4] and CN9[3, 5, 7, 8], drive on/off the correspondent OUTX
connected to the loads on the process side. The INX pins can be driven low/high swinging between 0V and VISO_L. The
activation of each OUTX (OUT1… OUT8) can be monitored by the green LEDs DOX (DO1… DO8).
The activation of the three diagnostic pins (TWARN, PGOOD, FAULT) can be visualized on the correspondent red LEDs (D11,
D12, D13, respectively) or monitored by an oscilloscope on CN8[5], CN5[9], CN5[10].
The SPI driving mode can be set by changing the default configuration (JP21 = close; SW4, SW5, SW6, SW7, SW9, SW10,
SW11, SW12, SW13, SW14, SW15 and SW20 = close 2-3, SW18 = close 1-2). The SPI-8bits is the default mode (JP22 =
open), while the SPI-16bits mode can be activated by JP22 = close.
In SPI driving mode it is also possible to activate the MCU freeze detection feature by setting SW3 = close 2-3.
The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board. In this case
the companion firmware X-CUBE-IPS detects the selected configuration (GPIO, SPI-8bits, SPI-16bits) by reading the signals
SEL2_L and SEL1 from CN8[1] and CN8[6]. The activation of the MCU freeze feature is detected by WDEN(in) on CN9[4].
It is also possible to evaluate a system composed of a X-NUCLEO-OUT16A1 stacked on other expansion boards. In fact, SPI
driving mode allows the daisy-chaining communication with another X-NUCLEO-OUT16A1 stacked through the Arduino
connectors: the two stacked boards must be configured with SW6, SW18 = close 2-3 on one board, and SW6, SW18 = close
1-2 on the other board.

1.1 Overview
The X-NUCLEO-OUT16A1 embeds the IPS8200HQ intelligent power switch (IPS), which features serial/parallel
selectable interface on-chip, 8-bit and 16-bit SPI interface for IC command and control diagnostic, Power Good
diagnostic, IC warning temperature detection, overcurrent and overtemperature protection for safe output loads
control.
The board is designed to meet the application requirements for the galvanic isolation between the user and power
interfaces.
An optical isolation satisfies this requirement. The isolation is implemented through three dual channel digital
isolators with 2 – 0 channel directionality (U3, U11, U12) for the input signals forward to the device, and four dual
channel digital isolators with 1 – 1 channel directionality (U4, U6, U7, U10) for the diagnostic feedback signals of
the device and the daisy chaining service lines.

1.3 Digital section
The digital section is associated with the STM32 interface and the digital supply voltage to and from the X-
NUCLEO-OUT16A1 expansion board.
Figure 2. X-NUCLEO-OUT16A1 expansion board: digital interface section
The dotted green line indicates the whole digital interface section. The pink rectangles identify the Arduino® UNO
R3 connectors and the yellow ones identify STISO620 and STISO621 digital isolators.
The four Arduino® UNO R3 connectors:
• allow the expansion board to communicate with the STM32 Nucleo development microcontroller board
accessing the STM32 peripheral and GPIO resources;
• provide the digital supply voltage between the STM32 Nucleo development board and the X-NUCLEO-
OUT16A1 expansion board, in either direction.
The five digital isolators (STISO620 and STISO621) provide 4 kVPK galvanic isolation between logic and process
sides of the expansion board.
Usually, the STM32 Nucleo development board supplies the expansion board by a 3.3 V or 5.0 V generated by
the USB.
UM3246
Digital section
UM3246 - Rev 1 page 5/25

Alternatively, it is possible to supply the STM32 Nucleo development board from the expansion board. In this
case, an external supply voltage (7-12 V) should be connected to the CN11 connector (not mounted by default)
on the expansion board and the ground loop should be closed by mounting D2 (enabling the reverse polarity
protection) or by closing JP11 (without reverse polarity).
To supply the VIN voltage rail, it is necessary to:
• close the JP5 jumper between pins 2 and 3 and open the JP1 jumper on the NUCLEO-F401RE;
• open the JP5 jumper between pins 1 and 2 and close the JP5 jumper between pins 3 and 4 on the
NUCLEO-G431RB.
Logic side is then supplied by the VISO_L rail (3.3 V or 5.0 V). VISO_L can be supplied by an external power
supply connected to CN13 (SW1 open) or, alternatively by the pin 4 (SW1 = close 1-2) or pin 5 (SW1 = close 2-3)
of CN6.
The user can select which driving mode controls the IPS8200HQ: parallel (SEL2 = L by JP21 = open) or SPI
(SEL2 = H by JP21 = closed). In the case of SPI selection, the user can select the communication protocol
between 8 bits (SEL1 = L by JP22 = open) or 16 bits (SEL1 = H by JP22 = closed).

UM3246 - Rev 1 page 6/25

1.4 Power section
The power section involves the power supply voltage (CN1, pin 1 for VCC, pin 2 for GND), the load connection
(eight loads can be connected between each pin of CN2, CN3, CN4, and CN12 and pin 2 of CN1), EMC
protections (U2), and supply reverse polarity protection (D1).

8. SEL1 H (16 bits SPI data width) yellow LED
The process side is supplied by the VCC and VISO_P rails. The VISO_P (3.3 or 5.0 V) is usually supplied by the
VREG rail (JP31 = closed) that can be generated by the step-down embedded in the IPS8200HQ (SW17 = close
1-2, JP20 = closed, JP15 = closed and JP28 = close 2-4 (VREG = 3.3 V) or JP28 = 1-3 (VREG = 5.0 V)).
Alternatively, VREG can be provided by an external power supply connected to CN14 (SW17 = close 2-3, JP20 =
open, JP15 = open).

UM3246 - Rev 1 page 7/25

For EMC:
• the SMC30J30CA transient voltage suppressor (U2), enabled by closing J9, is placed between VCC and
GND tracks to protect the IPS8200HQ against surge discharge on the supply rail path up to ±1 kV/2 Ω
coupling;
• in the common mode surge testing, two single-layer capacitors (C11 and C12 - not included) must be
soldered at the predisposed locations;
• the IPS8200HQ output stages do not require additional EMC protections with respect to the IEC61000-4-2,
IEC61000-4-3, IEC61000-4-4, IEC61000-4-5, IEC61000-4-8 standards.
The EMC performance of the X-NUCLEO-OUT16A1 is detailed below:
• for emission (when the DC input port of the board is powered by an AC-DC, DC-DC or battery with a cable
that does not exceed a three-meter length), compliance with standards:
– EN IEC 61000-6-3:2021
– EN 55032:2015 +A1:2020
• for immunity, compliance with standards:
– EN IEC 61000-6-1:2019
– EN 55035:2017 +A11:2020
