How Long Will CAN Stick Around As Rival Networks Speed Up?

As vehicles become more intelligent and software-defined, in-vehicle network architectures are undergoing significant transformation. While legacy protocols like CAN and LIN remain prevalent due to th... Read original →

The rise of Automotive Ethernet is triggering a cascading redesign across the in-vehicle stack: integration of TSN and MACsec compels Siemens EDA and Keysight to accelerate validation tools for IEEE 802.1AS/802.3DM, while pushing Rambus to embed cryptographic engines into PHY-layer IP. Regulatory pressure—especially EU GSR 2’s end-to-end cybersecurity mandates—exposes CAN/LIN-based ECUs to certification risks, inflating OEMs’ transition costs. Strategic divergence is clear: Infineon bets on hybrid Ethernet-CAN bridges to extend legacy viability, whereas Imagination aligns tightly with zonal architectures to push full-Ethernet domain controllers. Within 18 months, as AUTOSAR Adaptive and DoIP-over-TSN mature, LIN/CAN will rapidly retreat from non-safety domains. The real battleground? Seamless coexistence via automotive-grade digital twins—soon a non-negotiable Tier 1 capability.
