Infineon’s AURIX TC3xx multicore MCUs enable next-generation automotive designs

Infineon Technologies AG has announced the AURIX TC3xx family of automotive multicore microcontrollers (MCUs) based on up to six 300 MHz TriCore cores and up to 16 MB of Flash memory with more than 6 MB of integrated RAM. Four of the TriCore cores feature an additional lockstep core that enables ISO 26262 functional safety compliance for applications such as engine management and transmission control, hybrid domain control, inverter control, battery management, and safety-critical systems ranging from airbag, braking, and power steering to sensor-based systems using radar or camera technologies.

TC3xx MCUs are equipped with a radar processing subsystem and as many as two dedicated 300 MHz Signal Processing Units that allow radar algorithms to be computed on a single chip. New asymmetric cryptography accelerators integrated into the MCUs’ integrated hardware security modules (HSMs) help developers achieve full E-safety vehicle intrusion protected applications (EVITA) standard support.

The AURIX TC3xx family is compatible with the previous AURIX TC2xx generation, with interfaces including Gigabit Ethernet (GbE), up to 12 CAN-FD channels compliant to ISO11898-1, and up to 24 LIN channels. An additional eMMC interface to external Flash enables local data storage in support of software-over-the-air (SOTA) updates.

General sampling is scheduled for the first quarter of 2017, while qualification of the first product is planned in the first quarter of 2019. For more information, visit
