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.
Published characteristics
| CPU | 32-bit TriCore v1.3.1, up to 180 MHz in the stated automotive temperature range |
|---|---|
| Program flash | 4 MiB embedded program flash with error correction |
| Data flash | 64 KiB data flash providing 16 KiB emulated EEPROM |
| Other hardware | Peripheral control processor, CAN nodes, analogue inputs and on-chip debug support; see the product brief for details. |
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.
