Manchester, UK – 3September2020–The first development kit developed byRutronik, the RUTDevKit-STM32L5, is a complete solution for AI-basedapplications running on an MCU platform. It enables hardware and firmwaredevelopers to deliver proof-of-concepts within a short space of time.The focus here is firmly on security and data protection, short latency periods, low energy consumption and adequate storage resources.
Data generated by (I)IoT ((Industrial) Internet of Things) devices are increasinglyevaluated on MCU platforms within the application or close to theMCU-based embedded system. This is particularly the case in industrialenvironments, whether for security reasons or because of the required latencyperiods. When it comes to implementing this Edge AI or EdgeIntelligence(EI), Rutronik now offers a unique development kit that contains all thenecessary components. Every single module is from the Rutronik productportfolio, while the complete BOM is available at www.rutronik.com/development-kit.
The RUTDevKit-STM32L5 is based on the ultra-low-power high-performancemicrocontroller STM32L562ZET6Q, which operates at 110MHz. Its32bit RISC-Core Arm Cortex-M33 with Arm TrustZone offers hardware-basedsecurity features that ensure data security of the EI application duringthe inference phase. Thanks to Arm TrustZone, one core provides two independentprocessing environments: a protected one for cyber protection andsensitive code, and an unprotected one for the execution of untrusted code.
Further, Arm TrustZone also supports Secure Boot, thereby enabling secureread and write protection for the integrated memory (64Mbit PSRAM and128Mbit NOR flash) andcryptography acceleration. Arm TrustZone canalso include I/O ports, a peripheral function and flash or SRAM regions. TheOcto SPI interface to PSRAM and the Quad SPI interface to the NOR flashmemory along with the fast A/D converter of the microcontroller support short latency periods.
In addition to the microcontroller memory, the RUTDevKit-STM32L5 facilitatesuse of an SD card with several GB as well as a protected area to securelystore both raw data andinference data of the AI model.
Equipped with CAN FD and RS485 interface, the kit enables fast transmissionof largeamounts of data.
The USB-C power supply features Protection IC, and low power functionscan be tested with a battery. Additionally, there is the on-board ST-LINKV2 debugger / programmer as well as Arduino interfaces for supplementaryboards, such as an Anybus communication modulethat enables products tocommunicate via all common field buses and on Industrial Ethernet networks,e.g. EtherCat.
The kit also includes software and sample firmware, including a TrustZonedemo, a test mode demo for CAN FD, an RS485 Modbus demo, a USB powersupply and tamperdetection demo, and a dual bank flash bootloader demo.
