The microcontroller

Millions of connected devices are in use today, from beacons for contact tracking to trackable asset tags, all operating from small batteries, explained Patrick Moorhead, CEO, and chief analyst at Moor Insights & Strategy.  

The RSL15 is designed with Arm’s TrustZone technology to establish device root of trust as well as Arm’s CryptoCell-312 technology to protect the authenticity, integrity and confidentiality of code and data. The PSA Level 1-certified design enhances the security measures already part of the Bluetooth protocol, adds the company.

“The ability to protect against cyber threats is an essential differentiator for manufacturers choosing a wireless microcontroller for industrial IoT applications,” said Michel De Mey, vice president of the industrial solutions division at onsemi.

The microcontroller supports new capabilities provided by the Bluetooth 5.2 specification, including longer range, higher data transmissions and localisation through angle of arrival (AoA) and angle of departure (AoD). onsemi has also developed a smart sensing features whic allows the Arm Cortex-M33 processor to remain in a deep sleep mode while still monitoring sensor interfaces.

The RSL15 is suitable for a variety of industrial automation applications including connected asset tracking, smart retail and IoT edge nodes. It is available now in a miniature 40-pin QFN package.
