Technical features

System performance
The AURIX family devices range in the ultra high-end from a 300 MHz triple-core device with 8MB of embedded Flash to a 200 MHz triple core with 4MB of embedded Flash to a 200 MHz dual-core device with 2.5MB of embedded Flash right down to 130 MHz and 80 MHz single-core and single core lockstep devices with 1.5MB, 1MB and 0.5MB of embedded Flash. The package portfolio includes a BGA-516 package with a ball-compatible BGA-292 package (I/O subset), and compatible QFP-176, QFP-144, QFP‑100 to QFP-64 packages.

Safety
The AURIX architecture has been developed according to an audited ISO26262 compliant process and designed to meet ASIL-D on an application level. The platform uses up to 2 cores in TriCore lockstep mode, a lockstep architecture combined with safety technology such as safe internal communication buses or distributed memory protection systems. Hardware level encapsulation techniques allow integration of software with various safety levels (QM to ASIL-D) from different sources, reducing the system complexity of implementing those safety levels.

The AURIX architecture offers the following features that help in achieving a given safety level:

Hardware-focused safety concepts for reduced SW overhead
Lockstep with clock delay
Access permission system
Safety management unit
Safe DMA
I/O, clock and voltage monitors 
Safety Software for checking the functionality of the core
ISO 26262 conformance to support safety requirements up to ASIL-D

Security
Infineon has integrated a programmable Hardware Security Module (HSM) into the AURIX family in line with EVITA (E-safety vehicle intrusion protected applications). The security module was implemented by the market leader in chipcard technology using state-of-the art encryption technology. This “embedded chipcard” protects against attacks of IP infringement, fraud and software hijacking.

Supply security
Infineon has set up dual-fab manufacturing using two local separated Frontend production sites. Both sites are using identical certified processes and tooling. All products from both sides will be AEC-Q100 qualified and are manufactured in a 65 nm technology.

Tools and software
Infineon has several full-featured evaluation boards for their TriCore product line. Development tools for evaluation such as compilers, debuggers and AURIX Development Studio IDE are included, as well as technical documentation: user manuals, architecture manuals, application notes, data sheets, board documentation.
