Just thought I should post that as I have newly discovered this forum, and spotted that there was some feeling that the Aurix was a dying product. Fortuitously, I happen to have some on-going experience of it.
The Aurix is very much alive and is in fact being used by a large worldwide manufacturer, not of vehicles themselves, in a number of new and upcoming automotive products with a projected production life of many years. Indeed we are awaiting the arrival of a (cheaper) variant with less memory than the one that we are using on second-stage prototypes right now.
Personally I do not like them at all, as there is a great deal of hardware complexity, and therefore an immense amount of software detail that has to be just right. Simplicity is important for safety and reliability. But the various I/O blocks can do a lot by themselves without CPU overhead, once initialised. I do recommend a close study of the data sheets, there is much more there than you will think at first glance! Oh, and if you want MANY 12 bit analogue inputs, some fast, look no further!
Our product has a number of ASICs as well as the CPU, mixed technology with analogue bits, high voltage drivers and low voltage CMOS logic on the same chip, and as those are our own intellectual property, made by one of the well-known foundries, and used for years, they are quite affordable, as is the CPU. But development tools for the Aurix are eyewateringly expensive...
Which is why I prefer the TI TMS570. Dual core with error checking, but a lot simpler and based on the ARM architecture. Development boards are very affordable, much like an Arduino, I have two at home. The main development tool, Code Composer, is now free and runs on Linux or the other inferior operating system. What is there not to like?
