Product Brief
TC23xL – AURIX™ family
Enabling safety applications
AURIX™ is Infineon’s brand new family of microcontrollers serving the needs of all safety
critical automotive applications. It is based on a new generation TriCore™ cores, ranging
from single core devices, up to microcontrollers with 3 independent CPUs.
Additional lockstep cores provide excellent fault detection and fast reaction times for
ASIL-D safety systems.
The scalability in terms of performance, memory and packages within the AURIX™ family
allows for a common safety case across the dierent devices, allowing single applications
to be hosted on the smaller devices, but also allows multiple applications to be hosted in
parallel on the larger devices without the need to modify soware architecture or safety
strategies.
