Introducing the new STM32L5 with TrustZone® security (Arm® Cortex®-M33), featuring best-in-class power consumption and added peripheral set.

With the rapid expansion of the Internet of Things (IoT) market, device security has become a top requirement as customer information needs to remain confidential and safe from outside attacks.

As a new addition to the STM32 family, the STM32L5 integrates the Arm Cortex-M33 core with embedded TrustZone security technology to provide developers with a “Root of Trust” on which to build a secure application framework. TrustZone offers hardware protection that allows developers to isolate critical security firmware authentication and private information from other parts of the device.

In this session, we will present the STM32L5’s new peripherals, focusing on the TrustZone hardware feature that allows developers to partition a device into two worlds: trusted and non-trusted. We will demonstrate the processing efficiency and class-leading power consumption of the STM32L5, and introduce additions to the STM32 development ecosystem such as Secure Boot Secure Firmware Update (SBSFU) and Secure Firmware Injection (SFI) applications. Finally, we will show you how the STM32L5 can be paired with ST25 NFC/RFID technology to implement digital signature verification applications.

You will learn:

  • The new features and peripherals embedded in the STM32L5
  • How to create a “Root of Trust” with the STM32L5's security features
  • To use the STM32 Trusted Package Creator
  • How to interface the STM32L5 to other ST products (NFC) for digital signature verification applications
