HY-TTC 90

The HY-TTC 90 and the HY-TTC 94 are safety-certified and are the most powerful controllers in the 16-bit controller family. They meet all the technical requirements of modern vehicle electronics in the off-highway sector.
The HY-TTC 90/94 was developed in accordance with the international standards IEC 61508 and ISO/EN 13849 and is certified by TÜV NORD. Therefore, it meets the requirements of safety levels SIL 2 (Safety Integrity Level 2) and PL d (Performance Level d).
The HY-TTC 94 has 4 CAN bus interfaces and the same inputs and outputs as the HY-TTC 90.
For the CPU, it uses the safety CPU XC2287M which was specially developed by Infineon for safety applications. This offers expanded safety features for the protection of the internal
RAM and flash memories.
