ST X-NUCLEO-OUT12A1 User manual

Introduction
The X-NUCLEO-OUT12A1 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 ISO808A octal high-side smart power solid state
relay, with embedded galvanic isolation and 20MHz SPI control interface, in a digital output module connected to 0.7 A industrial
loads.
The X-NUCLEO-OUT12A1 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 ISO808A.
The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board.
It is also possible to evaluate a 16 channel digital output system enabling the daisy chaining feature on two X-NUCLEO-
OUT12A1 stacked expansion boards.

1Getting started
1.1 Overview
The X-NUCLEO-OUT12A1 embeds the ISO808A intelligent power switch (IPS), which features galvanic isolation,
20 MHz SPI and Power Good diagnostic, 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 ISO808A 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 ISO808A 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
– PGOOD (VCC voltage level alarm signalization)
– 20 MHz SPI with daisy chaining
– Fast decay for inductive loads
– Undervoltage lock-out

1.2 Digital section
The digital section is associated with the STM32 interface and the digital supply voltage to and from the
X-NUCLEO-OUT12A1 expansion board.
Figure 2. X-NUCLEO-OUT12A1 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-
OUT12A1 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 ISO808A can be supplied by the
3.3 V supply rail generated by the expansion board: in this case, on the X-NUCLEO-OUT12A1, 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 ISO808A independently by the
expansion board. In this case, on the X-NUCLEO-OUT12A1, 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
6. Power Good - red LED
For EMC:
•the SM15T39CA transient voltage suppressor (U2), enabled by closing J9, is placed between VCC and
GND tracks to protect the ISO808A 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 ISO808A 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-OUT12A1 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

1.6 Board setup
Step 1. Connect the mini-USB or micro-USB cable to your PC to use the X-NUCLEO-OUT12A1 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.

Note: By default, the X-NUCLEO-OUT12A1 is configured to work stand-alone. However, it is possible
to stack two X-NUCLEO-OUT12A1 and enable the related control by enabling the daisy chaining
communication:
– Close J12 [1-2] and J13 [3-4 ] in board #1
– Close J12 [3-4] and J13 [1-2 ] in board #2
– Rework board #1: remove R105 and mount R102
– Rework board #2: remove R119, R108, R107, R104 and mount R102, R113, R111, R109
In terms of software, it is necessary to generate the new binary file after having defined the
preprocessor directive USE_DAISY_CHAIN and removed the directive USE_PAR_IND (or changed
in noUSE_PAR_IND). The modification to control mode becomes effective on the binary files after
rebuilding.
Step 3. Connect the ISO808A device supply voltage via CN1 (see Section 1.3 Power section).
Step 4. Provide the digital supply voltage (see Section 1.2 Digital section).
Step 5. Connect the load on the output connector (see Section 1.3 Power section).
Step 6. Reset the example sequence by pushing the black button on the STM32 Nucleo board.
Step 7. Push the blue button on the STM32 Nucleo board to choose among the examples provided in the
default firmware package.
