Overview
The Infineon TC1797 is a 32-bit automotive microcontroller in the AUDO Future family, built around a TriCore v1.3.1 CPU. Infineon's product brief lists engine and transmission control among its applications. This part is an earlier AUDO device, not a member of the later AURIX range.

These specifications describe the TC1797 product in the cited brief; they are not universal specifications for TriCore or all EDC17 devices.
ECU example and identification
AutoTuner identifies Bosch EDC17CP46 with a TC1797. The ECU hardware revision, software and protection state determine what an individual supported tool can read or write. Record the complete identification and confirm memory coverage; the presence of embedded flash does not mean an OBD calibration read contains every memory region.
