Rutronik raids its product portfolio for AI development kit

Developed for AI-based applications running on a microcontroller platform, the RUTDevKit-STM32L5 is the first development kit developed by Rutronik. It enables hardware and firmware developers to deliver proof-of-concepts within a short space of time, says the distributor, while ensuring security and data protection, short latency periods, low energy consumption and adequate storage resources.

Data generated by industrial IoT (IIoT) are increasingly evaluated on microcontroller platforms within the application or close to the microcontroller-based embedded system. The RUTDevKit-STM32L5 contains all the necessary components and every module is from the Rutronik product portfolio.

The RUTDevKit-STM32L5 is based on STMicroelectronics’ low-power, high-performance microcontroller, the STM32L562ZET6Q, which operates at 110MHz. It has a 32bit RISC-Core Arm Cortex-M33 with Arm TrustZone for hardware-based security features to secure edge application data during the inference phase. Arm TrustZone is a single core with two independent processing environments. One is protected and reserved for cyber protection and sensitive code, the other is unprotected for the execution of untrusted code.

The TrustZone technology also supports Secure Boot, enabling secure read and write protection for the integrated memory (64Mbit PSRAM and 128Mbit NOR flash) and cryptography acceleration. It can also include I/O ports, a peripheral function and flash or SRAM regions. The Octo SPI interface to the PSRAM and the quad SPI interface to the NOR flash memory, together with the microcontroller’s fast ADC, support short latency periods, says Rutronik.

In addition to the microcontroller memory, the RUTDevKit-STM32L5 allows for the use of an SD card with several Gbyte of memory and a protected area to securely store both raw data and inference data of the AI model.

The kit has a CAN FD and an RS485 interface and a USB-C power supply with Protection IC. There is also an on-board ST-LINK V2 debugger / programmer and Arduino interfaces for supplementary boards, such as an Anybus communication module to communicate via all common field buses and on industrial Ethernet networks.

Software and sample firmware, a TrustZone demo, a test mode demo for CAN FD, an RS485 Modbus demo, a USB power supply and tamper detection demo, and a dual bank flash bootloader demo are also included.
