Introduction

STM32Cube is an STMicroelectronics original initiative to improve designer productivity significantly 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,

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 STM32CubeN6 for the STM32N6 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 ThreadX, FileX, LevelX, NetX Duo, USBX, USB PD, video

encoder API, and OpenBL

– 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

Package structure.

2 STM32CubeN6 main features

The STM32CubeN6 MCU Package runs on STM32 32-bit microcontrollers based on the Arm

The STM32CubeN6 gathers, in a single package, all the generic embedded software components required to

develop an application for the

STM32N6 series microcontrollers. In line with the STM32Cube initiative, this set of

components is highly portable, not only within the STM32N6 series microcontrollers but also to other STM32

series.

The STM32CubeN6 MCU Package also contains a comprehensive middleware component constructed around

3 STM32CubeN6 architecture overview

The STM32CubeN6 MCU Package solution is built around three independent levels that easily interact as

described in Figure 2.

DT73812V1

3.1 Level 0

This level is divided into three sublayers:

• Board support package (BSP).

• Hardware abstraction layer (HAL):

• Component:

• BSP driver:

BSP is based on a modular architecture allowing easy porting on any hardware by just implementing the low-level

routines.

HAL driver APIs are split into two categories:

• The low-layer APIs provide low-level APIs at the register level, with better optimization but less portability.
