•

NetX duo

–

Industrial grade networking stack: optimized for performance coming with many IoT protocols.

•

FileX/levelX

–

Advanced flash memory file system (FS) / flash memory translation layer (FTL): fully featured to

support NAND/NOR flash memories

•

USBX

–

USB host and device stacks coming with many classes

•

USB PD device and Core libraries

–

New USB Type-C® power delivery service. Implementing a dedicated protocol for the management of

power in this evolution of the USB.org specification. Refer to http://www.usb.org/developers/

powerdelivery/ for more details.

–

PD3 specifications (support of source / sink / dual role)

–

Fast role swap

–

Dead battery

–

Use of configuration files to change the core and the library configuration without changing the library

code (read only)

–

RTOS and standalone operation

–

Link with the low-level driver through an abstraction layer using the configuration file. The goal is to

avoid any dependency between the library and the low-level drivers

•

Open bootloader

–

It provides an open source bootloader with exactly the same features as the STM32 system

bootloader and with the same tools used for the system bootloader.

•

Arm trusted firmware-M (TF-M)

–

Reference implementation of the Arm platform security architecture (PSA) for TrustZone®

–

Secure services are:

◦

Secure storage service

◦

Attestation

◦

Crypto service

◦

TF-M audit log

◦

Platform service

Note:

An example of the TF-M application is available in the STM32CubeU5 firmware package under

\Projects\B-U585I-IOT02A\Applications\TFM.

•

MCU boot

•

Mbed™ crypto

–

Open source cryptography library that supports a wide range of cryptographic operations, including:

◦

Key management

◦

Hashing

◦

Symmetric cryptography

◦

Asymmetric cryptography

◦

Message authentication (MAC)

◦

Key generation and derivation

◦

Authenticated encryption with associated data (AEAD).

•

Network Library

–

It provides network services on STM32 devices.

–

It provides a socket API (BSD like style) with support of secure or nonsecure connection. It provides

also an API to control the lifecycle of the network adapters.

–

Three classes of network adapters are supported WIFI, Ethernet, and cellular. Different WIFI modules

are supported from third party vendors.

•

The STM32 touch sensing library:

–

Robust STMTouch capacitive touch sensing solution supporting proximity, touchkey, linear and rotary

touch sensors. It is based on a proven surface charge transfer acquisition principle.
