ST X-NUCLEO-OUT11A1 User manual

Introduction
The X-NUCLEO-OUT11A1 is an industrial digital output expansion board for STM32 Nucleo. It provides a powerful and flexible
environment for the evaluation of the driving and diagnostic capabilities of the ISO808 octal high-side smart power solid state
relay, with embedded galvanic isolation, in a digital output module connected to 0.7 A industrial loads.
The X-NUCLEO-OUT11A1 directly interfaces with the microcontroller on the STM32 Nucleo driven by GPIO pins and Arduino®
R3 connectors.
The galvanic isolation between the microcontroller and the process stage is guaranteed by the ISO808.
The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board.
It is also possible to evaluate a system composed of a X-NUCLEO-OUT11A1 stacked on other expansion boards.

1Getting started
1.1 Overview
The X-NUCLEO-OUT11A1 embeds the ISO808 intelligent power switch (IPS), which features galvanic isolation,
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.
The galvanic isolation embedded by the ISO808 satisfies this requirement, avoiding the necessity of external
optocouplers, with a consequent cost saving and a reduced application size.
The expansion board features:
• Based on the ISO808 octal high-side switch, which features:
– Operating range 9.2 to 36 V
– Low power dissipation (RON(MAX) = 260 mΩ)
– Process side operating current: up to 0.7 A per channel
– Embedded 2k VRMS galvanic isolation
– Direct (jitter < 20us) and synchronous (jitter < 6us) control modes
– Fast decay for inductive loads
– Undervoltage lock-out
– Overload and overtemperature protections
– Loss of ground protection
– PowerSO36 package
• Application board process side operating range: 10 (J10 open) to 33 V (J9 closed)
• Extended operating range of process side from 9.2 (J10 closed) up to 36 V (J9 open)
• Application board logic side operating voltage 3.3 to 5 V
• Green LEDs for outputs on/off status (J6 and J7 close 1-2, 3-4, 5-6, 7-8)
• Red LED for common overheating and communication error diagnostic (J3 close 1-2)
• Yellow LED for output enable status signalization (J3 close 5-6)
• Direct control mode (J1, J2 closed)
• Synchronous control mode (J1, J2 open)
• Process and logic supply rails reverse polarity protections
• Compatible with STM32 Nucleo development boards
• Equipped with Arduino® UNO R3 connectors
• RoHS and China RoHS compliant
• CE certified
• Radiated emission: class B according to the standard EN 55032

1.2 Digital section
The digital section is associated with the STM32 interface and the digital supply voltage to and from the
X-NUCLEO-OUT11A1 expansion board.
Figure 2. X-NUCLEO-OUT11A1 expansion board: digital interface section
The dotted green line indicates the whole digital interface section. The pink rectangles identify the Arduino® UNO
R3 connectors.
The four Arduino® UNO R3 connectors:
•allow the expansion board to communicate with the STM32 Nucleo development board microcontroller
accessing the STM32 peripheral and GPIO resources;
• provide the digital supply voltage between the STM32 Nucleo development board and the X-NUCLEO-
OUT11A1 expansion board, in either direction.
Usually, the STM32 Nucleo development board supplies the expansion board by a 3.3 V or 5.0 V generated by
the USB.
Alternatively, it is possible to supply the STM32 Nucleo development board by 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 J5 (without reverse polarity). In this scenario, the logic side of the ISO808 can be supplied by the
3.3 V supply rail generated by the expansion board: in this case, on the X-NUCLEO-OUT11A1, J4 must be closed
between pins 5 and 6.
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.
The pin 3 of the connector CN11 can be used to supply the logic side of the ISO808 independently by the
expansion board. In this case, on the X-NUCLEO-OUT11A1, the pins 1 and 2 of J4 must be closed (pins 5-6
open).

1.3 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).

2. Output and power supply connector
3. Output channels - green LEDs
4. Status (overtemperature) red LED
5. Output Enable yellow LED
For EMC:
•the SM15T39CA transient voltage suppressor (U2), enabled by closing J9, is placed between VCC and
GND tracks to protect the ISO808 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 ISO808 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-OUT11A1 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

1.4 Hardware requirements
The X-NUCLEO-OUT11A1 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEO-
G431RB STM32 Nucleo development boards.
To function correctly, the X-NUCLEO-OUT11A1 must be plugged onto the matching Arduino® UNO R3 connector
pins on the STM32 Nucleo board as shown below.
Figure 4. X-NUCLEO-OUT11A1 and STM32 Nucleo stack
1.5 System requirements

• a Windows PC/laptop (Windows 7 or above)
• a type A to mini-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-
F401RE development board
• a type A to micro-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-
G431RB development board
• the X-CUBE-IPS firmware and software package installed on your PC/laptop

1.6 Board setup
Step 1. Connect the mini-USB or micro-USB cable to your PC to use the X-NUCLEO-OUT11A1 with NUCLEO-
F401RE or NUCLEO-G431RB development board
Step 2. Download the firmware (.bin) onto the STM32 Nucleo development board microcontroller through
STM32 ST-LINK utility, STM32CubeProgrammer, and according to your IDE environment as detailed in
the table below.
The X-NUCLEO-OUT11A1 must be configured coherently to the selected control mode for ISO808-1:
J1 and J2 open (synchronous) or J1 and J2 closed (direct).
The binary files provided with the X-CUBE-IPS software package are generated by enabling the
synchronous control mode. The user can anyway set the preferred control mode by using the
preprocessor directive USE_SCM (for synchronous) or USE_DCM (for direct). The modification to
control mode becomes effective on the binary files after rebuilding.
