1 General information
The X-CUBE-SBSFU Expansion Package comes with examples running on the STM32L4
Series, STM32F4 Series, STM32F7 Series, STM32G0 Series, STM32G4 Series, STM32H7
Series, STM32L0 Series, STM32L1 Series, and STM32WB Series. An example combining
STM32 microcontroller and STSAFE-A100 is also provided for the STM32L4 Series.
X-CUBE-SBSFU is provided as reference code
for standalone STM32 system solution
examples demonstrating best use of STM32 protections to protect assets against
unauthorized external and internal access. X-CUBE-SBSFU proposes also a system
solution example combining STM32 and STSAFE-A100, which demonstrates HW Secure
Element protections for secure authentication services and secure data storage.
X-CUBE-SBSFU is a starting point for OEMs to develop
their own SBSFU as a function of
their product security requirement levels.
The X-CUBE-SBSFU Secure Boot and Secure
Firmware Update Expansion Package runs
on STM32 32-bit microcontrollers based on the Arm
®(a)
Cortex
®
-M processor.
