TASKING Extends Toolchain Support to Infineon’s RISC-V AURIX RC1 MCUs - EE Times Asia

Infineon's pivot of the AURIX RC1 to RISC-V is not an architecture decision—it is a structural decoupling from ARM's royalty model. TASKING's first-mover toolchain support is the real story: in automotive MCU, the kill chain runs from compiler to mass-production, not from die to die. The technical ripple is immediate. AURIX anchors engine and transmission control; migrating forces a full re-validation of AUTOSAR CP stacks and ISO 26262 ASIL-D certification. Upstream, SiFive and Andes gain a credible automotive validation path. Downstream, Bosch and Continental BSP adaptation windows open within 18 months. On compliance, TASKING's German origin aligns with the EU Chips Act's supply-chain sovereignty mandate. Infineon converts recurring ARM royalties into one-time IP licensing—a margin-structure shift, not a line-item tweak. Competitively, ARM's Cortex-R moat shows its first structural crack. IAR and Keil will follow within two quarters, but TASKING has locked the default-toolchain mindshare. More critically, GigaDevice and SinoWealth will ride this momentum; RISC-V automotive MCU penetration could breach 15% by 2026. Verdict: this is the first complete non-ARM commercial loop in automotive MCU in two decades. The window is 12 months.
