Infineon Technologies AURIX TC26xL 32-bit TriCore Microcontrollers
Infineon Technologies AURIX™ TC26xL 32-bit TriCore Microcontrollers are 200MHz MCUs with TriCore DSP functionality and up to 2.5MB flash memory with ECC protection. The TC26xL series is designed to meet the specific requirements of the automotive industry for performance and safety. The AURIX TC26xL MCUs range from single-core devices 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 different 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 software architecture or safety strategies.
