Infineon expands PSOC Control C3 family with secure MCUs for motor and power control - eeNews Europe

Infineon's move is not about "adding a security module"—it is about converting vertical integration in power semiconductors and control MCUs into a structural moat. By embedding hardware secure boot and cryptographic engines into the PSOC Control C3, Infineon positions squarely at the intersection of IEC 62443 and the EU's NIS2 directive. Within 18 months, VFDs, energy-storage BMS, and smart inverters will face procurement mandates that effectively eliminate non-secure MCUs from the bill of materials. Upstream, ARM's CryptoCell IP becomes a chokepoint; downstream, ABB and Siemens must re-architect firmware secure-boot chains. The sharper competitive edge: Infineon bundles SiC MOSFETs with control MCUs, delivering a "power + control + security" closed loop that NXP's S32K and ST's H7 cannot match at the system level. Expect NXP to bolt HSM options onto S32K3 by Q3 2025, and Microchip to accelerate PIC32MZ security certifications. The real wildcard is the China market: domestic players like GigaDevice and SinoWealth remain stuck at software-level encryption, with a 2–3-year gap in hardware trust roots (TRNG, secure boot). That hands Infineon a window in APAC industrial segments. The 24-month tail: secure MCUs shift from "premium option" to "entry ticket." Pure-play MCU vendors face further margin compression, while IDMs with power-device synergy—Infineon, onsemi—capture the largest share.
