GPIO

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.

STM32L4 series microcontroller software

The STM32 ODE software package X-CUBE-SAFEA1 provides a 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 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.
