Product details
Overview
TC297TP96F300SBBKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with dual-core lockstep architecture, 300 MHz CPU frequency, 4 MB embedded Flash, and integrated Ethernet MAC with IEEE 1588 support. It serves as the main safety controller in automotive ADAS domain controllers and chassis control units.
For engineers reviewing the TC297TP96F300SBBKXUMA1 datasheet, TC297TP96F300SBBKXUMA1 pinout, TC297TP96F300SBBKXUMA1 application, or TC297TP96F300SBBKXUMA1 equivalent, key selection criteria include ASIL-D compliance, multi-core lockstep validation, hardware-based memory protection unit (MPU), and real-time debug trace capability via DAP interface.
Technical Context
This MCU implements two independent TriCore™ TC1.6P cores operating in lockstep mode for fault detection, with a third independent core for application processing. It integrates a 12-bit SAR ADC with 48 channels, 64-channel GPT12 timer unit, and 6-channel SENT interface for sensor communication.
The device includes a dedicated Safety Management Unit (SMU) supporting ISO 26262 ASIL-D decomposition, and a Memory Protection Unit (MPU) enforcing strict memory access isolation between safety-critical and non-safety partitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC377TP128F300SBJXUMA1 | TriCore™ TC1.8P cores, 300 MHz, 8 MB Flash, no integrated Ethernet MAC | Targeted at higher-code-footprint powertrain applications where Ethernet is not required | Select when needing larger Flash and higher computational throughput without Ethernet connectivity |
| S32K344WAT0MLHT | ARM Cortex-R52 dual-core, 320 MHz, 4 MB Flash, integrated Ethernet AVB, no lockstep | Designed for functional safety up to ASIL-D but uses software-managed redundancy instead of hardware lockstep | Select when leveraging AUTOSAR Adaptive and requiring Ethernet AVB for OTA update distribution |
Compared with TC297TP96F300SBBKXUMA1, TC377 offers greater Flash capacity but lacks Ethernet, while S32K344 provides ARM ecosystem compatibility and AVB support but relies on software-based safety mechanisms rather than hardware lockstep.

FAQ
What is the maximum junction temperature rating for TC297TP96F300SBBKXUMA1?
The TC297TP96F300SBBKXUMA1 is rated for operation up to 150 °C junction temperature, validated per AEC-Q100 Grade 1 qualification. This enables deployment in engine bay and transmission control locations where ambient temperatures exceed 125 °C, provided thermal design meets Infineon's recommended PCB copper area and airflow guidelines.
Does TC297TP96F300SBBKXUMA1 support flash programming via JTAG or only via bootloader?
TC297TP96F300SBBKXUMA1 supports both JTAG-based flash programming using the DAP interface and UART/CAN-based bootloader updates. The JTAG path enables full chip erase, secure debug access, and boundary scan testing, while the bootloader supports field firmware upgrades without requiring debug hardware.
Is the Ethernet MAC in TC297TP96F300SBBKXUMA1 compatible with IEEE 802.1AS-2020?
Yes, the integrated Ethernet MAC supports IEEE 802.1AS-2020 via hardware timestamping and PTPv2 message handling in the MAC layer. It delivers sub-microsecond timestamp accuracy and supports transparent clock and end-to-end transparent clock modes for time-sensitive networking in automotive zonal architectures.
Can TC297TP96F300SBBKXUMA1 operate in single-core mode for non-safety applications?
Yes, the application core can be used independently while disabling lockstep mode on the safety cores, subject to configuration of the Safety Management Unit. However, ASIL-D certification applies only to the full lockstep configuration; standalone operation is suitable for non-safety tasks like diagnostics logging or infotainment bridging within the same ECU.
