Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC297TA128F300SBBKXUMA2 | Same silicon revision (BC-Step), identical pinout and electrical specs; differs only in mask set version for manufacturing traceability. | No functional difference; used interchangeably in production where lot-level qualification is required. | Select when matching exact wafer fab batch requirements or for legacy design continuity. |
| TC375LPD128F300SAAKXUMA1 | Newer AURIX™ TC3xx generation; adds HSM security module, higher clock (330 MHz), and larger L2 cache-but BGA320 package and non-pin-compatible. | Supports UDS secure boot and cryptographic acceleration; suited for next-gen Zonal E/E architectures requiring cybersecurity certification. | Choose for new designs needing ISO/SAE 21434 compliance and future-proof scalability beyond TC2xx lifecycle. |
Compared with TC297TA128F300SBBKXUMA1, the MA2 variant offers identical functionality with enhanced process traceability, while the TC375 introduces architectural upgrades (HSM, higher frequency) but requires PCB redesign due to package and pinout changes-making TC297 optimal for cost-sensitive, ASIL-D-compliant powertrain programs already in volume production.

FAQ
What safety certifications does TC297TA128F300SBBKXUMA1 support?
TC297TA128F300SBBKXUMA1 is designed to meet ISO 26262 ASIL-D requirements at the hardware level, with integrated lockstep cores, ECC on all memories, safe DMA, and hardware self-test capabilities. It supports FMEDA reports and safety manuals from Infineon, enabling systematic qualification for automotive safety-critical applications like engine control and brake-by-wire systems.
Does this MCU support Ethernet Time-Sensitive Networking (TSN)?
The TC297TA128F300SBBKXUMA1 includes a 10/100 Ethernet MAC compliant with IEEE 802.3, but lacks native TSN extensions (e.g., time-aware shaper, frame preemption). It supports standard Ethernet communication for diagnostics and firmware updates, and can be paired with external TSN switches for domain controller use cases requiring deterministic latency.
Can TC297TA128F300SBBKXUMA1 operate with a single 5 V supply?
No. TC297TA128F300SBBKXUMA1 requires three separate supplies: 1.3 V for the core, 3.3 V for I/O, and optionally 5 V for analog peripherals (e.g., DSADC reference). The datasheet specifies strict sequencing and voltage tolerances-using only a 5 V rail would damage the device. External PMICs like TLF35584 are recommended for proper power sequencing.
Is there a development board available for this specific variant?
Yes-Infineon's KIT_AURIX_TC297_TFT kit supports TC297TA128F300SBBKXUMA1 via socketed carrier board with debug interface, CAN/FlexRay transceivers, Ethernet PHY, and DSADC signal conditioning. It ships with DAVE™ IDE and AUTOSAR-compliant MCAL drivers, enabling rapid validation of safety-critical software stacks.
