Today we expect smart objects to fit seamlessly into our lives, anticipating our needs, yet requiring minimal attention themselves. Think about the smart watch on your wrist or the Amazon Echo in your home: invisibly processing data and getting smarter with each task. It doesn’t stop there; like a snowball gaining momentum, the next generation of devices in homes, cities and factories are beginning to seize the benefits that intelligent, connected devices offer.

The challenge for the semiconductor industry, however, is that this requires more processing power, more functionality and impenetrable security – all while running even longer on smaller batteries.

Today marks one step closer to that future reality, with ST’s announcement of the STM32L5 family, based on the Arm Cortex-M33 processor. This is the first ST product family to incorporate TrustZone technology for Arm Cortex-M processors, making possible system-wide software security and a new level of trust for embedded devices. The STM32L5 follows the STM32L4+ Cortex-M family, familiar to hundreds of thousands of developers, so there is a wealth of knowledge and resources available today to help speed up software development. The STM32L5 is the first STM32 based on the Armv8-M architecture with TrustZone security.
