ST X-NUCLEO-SAFEA1B Istruzioni operative

Introduction

The X-NUCLEO-SAFEA1B expansion board is based on the STSAFE-A110 secure element. It can be used with any STM32

Nucleo development board.

The on-board STSAFE-A110 is customized with a standard profile for evaluation and is compatible with the Arduino UNO R3

connector.

The X-NUCLEO-SAFEA1B expansion board is used with free X-CUBE-SAFEA1 or X-CUBE-SBSFU software packages

containing sample code to demonstrate how to implement security applications.

1 Getting started

1.1 Hardware requirements

The X-NUCLEO-SAFEA1B expansion board can be connected to any STM32 Nucleo development board through

the matching Arduino UNO R3 connector pins.

Note: Handle the X-NUCLEO-SAFEA1B with care and avoid bending or damaging the pins as the board has male/

female pass-through connectors and ESD sensitive components.

1.2 System requirements

To complete the system setup, you need:

• a PC running Windows version 7, 8 or 10

• a USB type A to mini-B USB cable to connect the STM32 Nucleo to the PC

• software package (X-CUBE-SAFEA1 or X-CUBE-SBSFU) installed on the user PC

• one of the compatible software development environments: IAR, Arm Keil, AC6, or Atolic

2 Hardware description

The X-NUCLEO-SAFEA1B expansion board has an embedded STSAFE-A110 secure element to allow you to

evaluate its authentication and data management services connected to a local or remote host.

This STSAFE-A110 is factory personalized with a generic sample profile.

The main features of the X-NUCLEO-SAFEA1B expansion board are:

• On-board STSAFE-A110 customized with a standard evaluation profile

• HE10 extension connector to mount additional STSAFE devices

• Arduino UNO R3 connector

• Free drivers, middleware and software samples compatible with the STM32 ODE

• RoHS and WEEE compliant

The X-NUCLEO-SAFEA1B interfaces with the STM32 Nucleo microcontrollers via the I²C communication bus.

2.1 Jumpers and solder bridges

Table 1. X-NUCLEO-SAFEA1B expansion board jumper and solder bridge functions

Jumper Alternative soldering point function

P1 SB13 Connects embedded LD3 green LED to STM32 Nucleo board

P4 SB1 Connects embedded 2.2kΩ pull-ups to I²C bus for SCL

P5 SB2 Connects embedded 2.2kΩ pull-ups to I²C bus for SDA

P7 Can be used to put STSAFE-A110 secure element in reset mode

SB5 Can be used to drive the STSAFE-A110 reset pin via the STM32 MCU PC0 GPIO

2.2 Connector

X-NUCLEO-SAFEA1B Nucleo expansion board has an HE10 extension connector (J2) to mount an additional

STSAFE-A1xx secure element.

Note: If you use the connector to accommodate new generation STSAFE-A devices, be sure that you insert jumper P7

to place the current STSAFE-A110 secure element soldered on the board in reset mode.

3 STM32L4 series microcontroller software

The STM32 ODE software package X-CUBE-SAFEA1 provides demonstration source code for a NUCLEO-

L476RG development board with X-NUCLEO-SAFEA1B expansion. The X-CUBE-SAFEA1 package includes

drivers, middleware and several demonstration codes that implement the features of the STSAFE-A110 device

through a host microcontroller. The demonstration codes use the STSAFE-A1xx middleware built on the

STM32Cube software technology. They illustrate authentication, key pair generation, key establishment, local

envelope wrapping and pairing features.

Another package, called X-CUBE-SBSFU, provides demonstration source code for Secure Boot and Secure

Firmware Update solution. It updates of the STM32 microcontroller firmware with new features and addresses

potential issues. The update process is a secure operation using the STSAFE-A110 to prevent unauthorized

updates and access to confidential on-device data. It is available for the STM32L4 Series microcontrollers with

examples provided for the B-L475E-IOT01A discovery kit with the X-NUCLEO-SAFEA1B expansion.
