RISC-V® Microcontrollers

Founded more than 10 years ago, RISC-V® is today an open source alternative and an open standard to proprietary RISC / ISA chip architectures. Emerging originally from a project at Berkeley University in California, RISC-V® International (www.riscv.org) established itself in 2015 as an organization and community consisting of software and hardware companies that are further developing and promoting the RISC-V® ISA. iSYSTEM is a member of RISC-V® International.

BlueBox Solutions

iSYSTEM provides comprehensive debug and trace support for the entire RISC-V® ecosystem of microcontrollers and SoCs.

iSYSTEM's iC5700 BlueBox complements the RISC-V family support with their IOM Accessories. With the CAN/LIN Module, vehicle network traffic and with the ADIO Module analog and digital signals surrounding the microcontroller can be traced and correlated with the application timing measurements. Complex AUTOSAR applications can be analyzed and time optimized to ensure that timing constraints are fulfilled.
