Features
• Protected environment for code and data
• Access to cryptographic operations
Description
The SE-MW STM32Cube secure engine (SE) middleware provides a protected
environment to manage all critical data and operations (such as cryptography
operations accessing firmware encryption key, and others).
Protected code and data are accessible through a single entry point (call gate
mechanism). Any access to the SE protected code or data without passing through
the call gate mechanism triggers a system reset.
Depending on the STM32 microcontroller, one of the two secure engine
implementations provided can be used: the firewall-based or the MPU-based secure
engine isolation.

What is STM32Cube?
STM32Cube is an STMicroelectronics original initiative to significantly improve designer's productivity by reducing
development effort, time, and cost. STM32Cube covers the whole STM32 portfolio.
STM32Cube includes:
• A set of user-friendly software development tools to cover project development from conception to
realization, among which are:
– STM32CubeMX, a graphical software configuration tool that allows the automatic generation of C
initialization code using graphical wizards
– STM32CubeIDE, an all-in-one development tool with peripheral configuration, code generation, code
compilation, and debug features
– STM32CubeProgrammer (STM32CubeProg), a programming tool available in graphical and command-
line versions
– STM32CubeMonitor (STM32CubeMonitor, STM32CubeMonPwr, STM32CubeMonRF,
STM32CubeMonUCPD) powerful monitoring tools to fine-tune the behavior and performance of STM32
applications in real-time
• STM32Cube MCU and MPU Packages, comprehensive embedded-software platforms specific to each
microcontroller and microprocessor series (such as STM32CubeWL for the STM32WL Series), which
include:
– STM32Cube hardware abstraction layer (HAL), ensuring maximized portability across the STM32
portfolio
– STM32Cube low-layer APIs, ensuring the best performance and footprints with a high degree of user
control over hardware
– A consistent set of middleware components such as FatFS, SBSFU and FreeRTOS
™
, plus LoRaWAN
®
and sub-GHz PHY connectivity services
– All embedded software utilities with full sets of peripheral and applicative examples
• STM32Cube Expansion Packages, which contain embedded software components that complement the
functionalities of the STM32Cube MCU and MPU Packages with:
– Middleware extensions and applicative layers
– Examples running on some specific STMicroelectronics development boards
