Product details

Overview

X-NUCLEO-SAFEA1A from STMicroelectronics is an Arduino UNO R3– and STM32 Nucleo–compatible expansion board featuring the STSAFE-A110 secure element in UFDFPN8 (3×2 mm) and SO8N packages, supporting I²C-based host authentication, secure boot, and firmware update via X-CUBE-SBSFU. It enables rapid evaluation of hardware-rooted security in embedded IoT endpoints.

For engineers reviewing the X-NUCLEO-SAFEA1A datasheet, X-NUCLEO-SAFEA1A pinout, X-NUCLEO-SAFEA1A application, or X-NUCLEO-SAFEA1A equivalent, this board delivers pre-provisioned STSAFE-A110 devices with standard evaluation profile, Arduino/R3 and Morpho connector compatibility, and integrated pull-up resistors for SDA/SCL/RESET lines.

Technical Context

The board hosts two STSAFE-A110 secure elements-one in UFDFPN8 and one in SO8N-each connected to the host MCU via dedicated I²C buses with independent reset control (RESET-C1/RESET-C2) and 3.3 V supply. All I²C lines include 4.7 kΩ pull-ups per ST's recommended interface design.

It integrates dual LED indicators (green LD1, amber LD3), user-configurable jumpers (SB1–SB5) for signal routing and pull-up selection, and supports both SPI (via CN5/CN8) and I²C (via CN5-6) host communication paths depending on configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
Form Factor	Arduino UNO R3–compliant expansion board with STM32 Nucleo Morpho headers
Secure Element	STSAFE-A110 (dual instances: UFDFPN8 + SO8N) pre-programmed with standard evaluation profile
Host Interface	I²C (SCL/SDA) with dedicated reset lines; SPI signals available via CN5/CN8 for alternate use
Power Supply	3.3 V only; no onboard voltage regulation - derives power from host Nucleo board
On-board Peripherals	Two status LEDs (LD1 green, LD3 amber), five configuration jumpers (SB1–SB5), and I²C pull-up resistors (4.7 kΩ)
Software Support	Fully compatible with X-CUBE-SAFEA1 (security demo suite) and X-CUBE-SBSFU (secure boot & firmware update)

Availability

FAQ

Does X-NUCLEO-SAFEA1A require external power or programming hardware?

No. The board draws 3.3 V power directly from the host STM32 Nucleo board via Arduino or Morpho connectors. It contains pre-provisioned STSAFE-A110 devices with standard evaluation profile - no external programmer or provisioning tool is needed to begin evaluation.

Can both STSAFE-A110 devices on the board be used simultaneously?

Yes. Each STSAFE-A110 (UFDFPN8 and SO8N) has independent I²C addresses and dedicated reset lines (RESET-C1/RESET-C2), enabling concurrent operation with separate host-side drivers or time-multiplexed access using distinct I²C bus instances on the host MCU.

Which STM32 Nucleo boards are compatible with X-NUCLEO-SAFEA1A?

All STM32 Nucleo-64 and Nucleo-144 boards with Arduino UNO R3 and Morpho headers are supported, including NUCLEO-F401RE, NUCLEO-L476RG, NUCLEO-H743ZI2, and NUCLEO-G071RB - verified by ST's official X-CUBE-SAFEA1 integration guide.

Is X-NUCLEO-SAFEA1A RoHS and WEEE compliant?

Yes. The board complies with RoHS Directive 2011/65/EU and WEEE Directive 2012/19/EU, as confirmed in ST's DB4051 data brief Rev 3 (June 2023) and product change notification STSAFA110DFSPL02.
