APPKIT_A2G_SAFETY

The development of a safe application can be a challenge when it comes to follow strict safety rules. In order to ease the development of such applications, Infineon provides the AURIX^TM TC3xx Safety manual. The safety manual defines so called safety mechanisms as an activity or a technical solution to avoid or control systematic fault failures and to detect random hardware failures or control random hardware failures.  Safety mechanism are classified in two main types

• The technical solution internal to the MCU by hardware(HW) or software (SW)
• The technical solution either in HW or SW, implemented at System level by the system integrator.

The main intention of the AURIX^TM  Application kit – TC3xx Safety is to provide implementation hints and code example to enable the worldwide community  to use and understand the functional safety aspects of AURIX^TM microcontroller. The kit demonstrate the implementation of various Safety Mechanism (SM) and other diagnostics functionalities. The real time data is shown on TFT display and ASCLIN shell Interface and the fault can be injected with touch screen and buttons/switches available on the board. The AURIX^TM  Application kit – TC3xx Safety consists of AURIXTM  TC397 Application kit TFT (KIT_A2G_TC397_5V_TFT) connected to the add-on shield board called Evaluation Board AURIX^TM TC3xx Safety (EVABOARD_A2G_SAFETY), Power supply, USB Cable, small magnet, quick start guide and pre-flashed SW.
