TC297TP128F300SBCKXUMA1 Übersicht
Background Knowledge: AURIX (Automotive Realtime Integrated NeXt-generation architecture) is Infineon's second-generation TriCore microcontroller family designed for safety-critical automotive applications. TriCore combines the real-time capability of a microcontroller, the computational power of a DSP, and the interrupt responsiveness of a RISC CPU in a single core ISA. Within the AURIX taxonomy, TC29xT sits in the upper-performance tier: multicore (up to 3 TriCore CPUs), large Flash (8 MB), and abundant peripherals, supporting ISO 26262 ASIL-D system designs without external lockstep companion chips.
Key features include three independent 300 MHz TriCore v1.6 CPUs, 8 MB program Flash with ECC, 728 KB SRAM, hardware security module (HSM) and EVITA-Full support, GTM for motor and timer orchestration, six CAN FD nodes, and 1 Gbit Ethernet. The 292-ball LFBGA package exposes the full peripheral set, including multiple SENT, PSI5, SPI, and LIN interfaces. Hardware over/under-voltage monitors and a built-in self-test (BIST) engine support ISO 26262 decomposition to ASIL-D at the system level.
Architecturally, the TC297T uses lockstep and delayed-lockstep CPU pairs (depending on configuration) and dedicated checker cores to detect soft errors; the GTM provides parallel PWM and capture channels independent of CPU load, which is critical for deterministic motor control and fuel-injection timing. Memory is protected by ECC on Flash and parity/ECC on SRAM, and a Hardware Security Module isolates cryptographic keys for secure boot and OTA updates.
Typical applications include automotive zone and domain controllers, electric-vehicle inverter and battery management controllers, ADAS sensor fusion pre-processors, chassis ECUs (braking, steering, suspension), and industrial safety controllers requiring IEC 61508 SIL-3. The combination of three cores and rich peripherals makes it well suited to chassis-domain ECUs where sensor acquisition, motor control, and vehicle-network gateway tasks run concurrently.
When designing with this part, allocate generous PCB copper for the 292-ball LFBGA (a 4-layer minimum stack-up is recommended), keep analog 3.3 V supplies quiet (the EVRA regulator pin is noise-sensitive), and follow Infineon AURIX Application Note AP32267 for oscillator and PLL layout. The HSM must be provisioned before secure boot is enabled, so plan factory key injection in your manufacturing flow.

Typische Anwendungen
TC297TP128F300SBCKXUMA1 ist geeignet für 6 Anwendungs: Automotive Zone/Domain Controller, Electric Vehicle Inverter/BMS Controller, ADAS Sensor Fusion Pre-Processor, Chassis ECU (Braking/Steering/Suspension), Industrial Functional-Safety Controller (IEC 61508), Secure Gateway/Vehicle Central Server.
Automotive Zone/Domain Controller
The TC297TP128F300SBCKXUMA1 suits vehicle zonal and domain controllers that aggregate sensor data and actuate ECUs over CAN FD and 1 Gbit Ethernet. Three TriCore cores at 300 MHz run AUTOSAR Classic/Adaptive stacks concurrently: one core on communication stacks (PDU routing, SOME/IP), one on real-time vehicle dynamics, and one on diagnostic (UDS, DoIP) services. The 8 MB Flash holds full AUTOSAR BSW plus application software; 728 KB SRAM accommodates large CAN/CAN-FD buffers and Ethernet frames. ISO 26262 ASIL-D decomposition lets the same MCU serve braking, steering, or powertrain domains without a separate lockstep companion chip. Power dissipation in a typical domain controller stays below 2 W, allowing passive cooling on a 4-layer FR-4 PCB.
Empfohlen
Electric Vehicle Inverter/BMS Controller
The TC297TP128F300SBCKXUMA1 is well-matched to EV traction inverter and battery management controllers thanks to its dedicated Generic Timer Module (GTM) and three-core architecture. The GTM generates the PWM waveforms for the 3-phase inverter with sub-microsecond resolution, independent of CPU load, while two TriCore cores run field-oriented control (FOC) loops at 10-20 kHz and the third handles CAN FD comms with the vehicle and BMS state-of-charge estimation. ASIL-D capability and ECC-protected 8 MB Flash satisfy ISO 26262 for xEV propulsion. Hardware Security Module provides secure boot and OTA key storage for the BMS. The 292-ball BGA package exposes enough SENT channels for cell-voltage and temperature monitoring daughter boards.
Empfohlen
ADAS Sensor Fusion Pre-Processor
For ADAS sensor-fusion pre-processing in L2/L2+ ADAS systems, the TC297TP128F300SBCKXUMA1 provides deterministic compute headroom without the cost of an SoC-class part like the TC397. Three TriCore cores at 300 MHz parse radar object lists (from front-corner 77 GHz radars), fuse them with camera-detected lane markings over Ethernet AVB, and output a curated object list to the central ADAS SoC. ISO 26262 ASIL-B(D) is achievable by using the lockstep pair plus checker monitor, suitable for surround-view and parking systems. The 1 Gbit Ethernet MAC streams raw sensor data upstream; six CAN FD nodes handle chassis sensor aggregation. 728 KB SRAM fits typical tracking-Kalman-filter state vectors for 32 dynamic objects in real time.
Empfohlen
Chassis ECU (Braking/Steering/Suspension)
Chassis ECUs for electronic stability control, electric power steering, or active suspension rely on the TC297TP128F300SBCKXUMA1 for ASIL-D torque-vectoring and steering control loops. The GTM runs wheel-speed pulse counters and motor PWM at 20 kHz; two TriCore cores execute vehicle-dynamics observers (side-slip, yaw-rate) at 1 kHz, and the third handles CAN FD communication with the vehicle network and sensor diagnostics. The Hardware Security Module secures the calibration area, preventing unauthorized tuning of steering feel - a regulatory requirement in many regions. The 292-ball BGA footprint allows compact PCB integration in steering-column or brake-module enclosures with passive cooling up to 2 W dissipation.
Empfohlen
Industrial Functional-Safety Controller (IEC 61508)
Beyond automotive, the TC297TP128F300SBCKXUMA1 supports industrial IEC 61508 SIL-3 safety controllers such as robot safety PLCs, servo drives, and process-safety shutdown systems. The three lockstep-capable TriCore cores, ECC Flash, and BIST engine satisfy SIL-3 architectural constraints without external watchdog MCUs. The GTM drives industrial PWM outputs for motor control and synchronizes with the safety-rated Ethernet/IP or PROFIsafe stack. Six CAN FD nodes allow redundant fieldbus channels. The 292-ball BGA is suitable for industrial temperature-grade products when paired with a heatsink; operating from 3.3 V or 5 V supply simplifies integration with existing 24 V-rail industrial designs that use standard buck converters.
Empfohlen
Secure Gateway/Vehicle Central Server
The TC297TP128F300SBCKXUMA1 acts as the central secure gateway connecting powertrain, chassis, body, and infotainment CAN/CAN-FD buses to the Ethernet backbone. Three TriCore cores partition tasks: one routes Ethernet packets, one handles CAN/LIN gateway translation, and one runs the HSM-secured diagnostic/OTA services. EVITA-Full hardware cryptography enables TLS 1.3, MACsec on Ethernet, and SecOC for CAN messages - protecting against CAN-injection attacks. Eight MB Flash stores routing tables, firewall rules, and large OTA staging buffers; the 1 Gbit Ethernet MAC uplinks to the central compute SoC. ISO 26262 ASIL-D capability lets the gateway safely disable non-critical ECUs during fault conditions to maintain drive-away function.

Wichtigste Unterscheidungsmerkmale
- ISO 26262 ASIL-D full support with EVITA-Full HSM in a single package (vs. TC297TP128F300NBCKXUMA1)
- Three 300 MHz TriCore cores for redundant parallel task scheduling (vs. TC277TP128F200NBCKXUMA1)
- 8 MB Flash supports full AUTOSAR Adaptive stack plus application code (vs. TC299TP128F300NBCKXUMA1)
Designhinweise
The PG-LFBGA-292-6 package has 0.8 mm ball pitch and a thermal pad. Use a 4-layer PCB minimum with a continuous inner ground plane directly beneath the BGA to provide a thermal return path and reference for high-speed traces. Stitching vias should surround the BGA perimeter at 1-2 mm spacing. Matched-length impedance control of 50 ohm single-ended / 90 ohm differential is mandatory for the RGMII Ethernet traces to the external PHY; route them on a dedicated inner layer with reference ground plane unbroken.
The TC297TP128F300SBCKXUMA1 requires a clean, low-noise 1.25 V core supply (VDD) capable of sourcing up to 1.5 A peak with sub-50 mV ripple. Use a dedicated Infineon TLF35584 or similar multi-rail PMIC with integrated watchdog and voltage supervision for ISO 26262 ASIL-D compliance. Place 10 uF X7R + 100 nF X7R ceramic bypass capacitors within 2 mm of every VDD/VSS ball pair. The EVRA analog supply pin (3.3 V) must be heavily filtered - this rail powers the ADC converters and any noise here directly couples into sensor measurements.
Common pitfalls include: (1) forgetting to provision the HSM before enabling secure boot, which bricks the device until factory key injection; (2) using a single 5 V supply for both 5 V CAN transceivers and the 3.3 V VDD rail without a buck regulator - the TC297T needs its own LDO; (3) routing the 40 MHz crystal traces asymmetrically - the crystal must be within 5 mm of the XTAL pins with matched-trace length and a ground guard ring; (4) ignoring the maximum Flash write endurance of 1,000 cycles per sector, which causes silent bit-flips in diagnostic logs. Always read the Infineon TC29xT errata sheet before firmware bring-up.
