This marks another milestone in the long-standing partnership between the two companies, as Lauterbach continues to provide comprehensive toolchain support across SemiDrive's entire portfolio of mass-production vehicle chips.

SemiDrive specializes in supplying high-performance, highly reliable automotive-grade chips, with a product lineup that spans intelligent cockpit and vehicle control applications—two of the most critical areas in future automotive electronic and electrical architectures. As the flagship model in its intelligent vehicle control series, the E3650 sets a new benchmark for domestically developed, high-end automotive-grade MCUs. Built on ARM's latest Cortex-R52+ cores with a high-performance lockstep multicore cluster, the E3650 reaches a top frequency of 600MHz—leading its class in real-time and safety capabilities. It also integrates up to 16MB of embedded non-volatile memory and features high-capacity SRAM, meeting the intense compute and response requirements of domain controller scenarios.

Designed to power a broad range of key automotive functions—including zonal controllers, VMC chassis control, smart cockpit/autonomous driving domain control, and powertrain management—the E3650 began sampling with customers in early 2025 and has already been designated by multiple leading automakers.

TRACE32® now supports the entire suite of SemiDrive's automotive-grade chips for both cockpit and vehicle control applications. Its robust debugging capabilities include heterogeneous multicore debugging, analysis of real-time operating systems such as Linux, QNX, and FreeRTOS, and support for Hypervisor environments. The platform enables advanced tasks like complex issue tracing via code tracking, performance analysis, and code coverage testing. Developers can also utilize TRACE32® scripting tools and third-party APIs (including C, C++, and Python) to enable automated testing and expand functionality as required by specific projects. With features like Complex Trigger Language, TRACE32® enhances debugging in complex use cases involving SemiDrive chips.

Specific to the E3650, the TRACE32® offers seamless integration with a dedicated menu option for one-click debug initialization. (Image 1)
