The StarSOM-STM32V8 (SLS08) family is a miniature computing module based on the STM32V873XJH6 MCU, which features high-performance real-time microcontrollers. The main core is an ARM Cortex-M85 running at speeds of up to 800 MHz, supported by 4 MB of non-volatile memory NVM manufactured using FD-SOI 18 nm technology. The semiconductor structure of the STM32V8 is resistant to operation at temperatures of up to 140°C. The StarSOM-STM32V8 (SLS08) modules are optionally equipped with an Ethernet PHY interface.
The StarSOM-STM32V8 is a low-power, highly integrated System-on-Module (SoM) offering high computational performance, real-time functionality, and MCU-level usability. Advanced security features include TrustZone and a built-in cryptographic coprocessor supporting AES, HMAC, MD5, SHA-1, SHA-2, and more. Integrated ChromART, Chrom-GRC, and a TFT LCD controller make it an ideal solution for home and industrial control systems, wireless applications, communication solutions, and real-time systems.
The square-shaped PCB of the StarSOM-STM32V8 (SLS08) module is equipped with low-profile board-to-board connectors with 2 × 100 pins.
For evaluation purposes, we recommend the dedicated StarCB-STM32V8-STD carrier board.
