Rutronik developed its first development kit Rutdevkit-STM32L5 for AI-based (artificial intelligence) applications at the edge. The kit provides a CAN FD interface.
The kit is based on the 110-MHz STM32L562ZET6Q micro-controller. Its 32-bit Arm Cortex-M33 processor with Arm Trustzone function offers hardware-based security features. The core provides a protected processing environment for cyber protection and sensitive code, as well as an unprotected processing environment for the execution of untrusted code. It also supports the secure boot enabling secure read and write protection for the integrated memory and cryptography acceleration.
The kit is equipped with a CAN FD interface using the TLE9251VLE transceiver. Further interfaces include EIA-485 and USB. The USB-C power supply is available. The ST-Link V2 debugger and programmer interface is on board. Also integrated is an Arduino interface for supplementary boards, such as the Anybus communication module by HMS. The latter enables the devices to communicate via diverse field-buses and Industrial Ethernet networks. In addition to the micro-controller memory (8-MiB PSRAM and 16-MiB NOR flash), the kit enables to use a micro-SD card with several GiB of memory as well as a protected area to securely store raw data and inference data of the AI model.
The kit includes a test mode demo for CAN FD, an EIA-485 Modbus demo, a USB power supply and tamper detection demo, as well as a dual-bank flash boot-loader demo.
