Addressing the key challenges of next-generation body integration and zone-oriented vehicle architectures, the Stellar G series ensures performance, safety, and power efficiency combined with wide connectivity and high security.
Next-generation vehicles will be Ethernet-centric, faster, secure network and have higher bandwidth, is essential to ensure fast transfer of large and ever-growing amount of data. Stellar G is an Ethernet-ready series with Ethernet communication up to 1 Gbps, as well as an integrated TSN switch to enable multiple network topologies. Featuring flexible low-power modes supporting low-quiescent current and an intelligent monitoring subsystem, Stellar G microcontrollers ensure the best overall power efficiency.
The Stellar G series is engineered to address the performance, safety, and power efficiency demands of zone-oriented vehicle architectures. It is the ideal device for Ethernet-centric vehicles, enabling multiple cost-efficient topologies thanks to its high-speed connectivity (up to 1 Gbps) and an integrated Time-Sensitive Networking (TSN) Switch. This integration is central to simplifying networking and ensuring the fast, secure transfer of data across complex vehicle domains. Featuring flexible low-power modes supporting low-quiescent current and an intelligent monitoring subsystem, Stellar G microcontrollers ensure the best overall power efficiency.
Applications
Delivering high real-time, deterministic processing, Stellar G MCUs feature up to six Arm ® Cortex®-R52 cores. The key advantage is the flexibility to run these cores in either Split-lock (for high performance) or Lockstep (for maximum safety). This allows you to configure the device to achieve the maximum performance possible while meeting the specific safety level and processing capability requirements of diverse applications.
