TC265D40F200WBCKXUMA1 Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash + SRAM), peripherals, and I/O on one silicon die. The AURIX TC2xx family is engineered for safety-critical embedded systems, combining lockstep TriCore cores, hardware security modules, and ASIL-D capable peripherals. Within the broader taxonomy, the TC265D40F200WBCKXUMA1 belongs to: MCU -> 32-bit MCU -> TriCore architecture -> AURIX family -> TC26xD sub-family -> automotive-grade MCU.
Key features include 2.5 MB of program Flash, on-chip SRAM, a 200 MHz dual-core TriCore CPU with DSP instructions, and a rich peripheral mix including multiple CAN-FD nodes, SPI, LIN, QSPI, ASCLIN, and timers. The part also embeds a Programmable HSM (Hardware Security Module) for secure boot, key storage, and EVITA-Full cryptography, along with a GTM (Generic Timer Module) for complex PWM and motor-control tasks.
The TC26xD implements Infineon's TriCore instruction set, which fuses RISC, DSP, and microcontroller paradigms in a single load/store architecture with deterministic interrupt latency. Built on a 40 nm embedded Flash process, it operates from a 3.3 V / 5 V supply with internal core logic on a separate voltage domain. Memory protection, ECC on Flash/SRAM, and lockstep compare logic support ASIL-D safety integrity when configured in dual-core lockstep mode.
Typical applications include automotive body domain controllers, electric power steering, airbag ECUs, battery management systems, and industrial servo drives. The wide temperature range and integrated peripherals make it suitable for chassis, powertrain, and ADAS sensor fusion subsystems where deterministic performance and hardware security are mandatory.
When designing with this part, provide at least four decoupling capacitors (100 nF + bulk) near each supply pin, follow Infineon PCB layout guidelines for the LQFP-176 EP package, and configure the HSM for secure boot before deploying production firmware. Use Infineon's AURIX Development Studio and the iLLD (Infineon Low-Level Driver) libraries to shorten firmware bring-up.

Typical Applications
TC265D40F200WBCKXUMA1 is suitable for 6 applications: Automotive Body Domain Controller, Electric Power Steering (EPS) ECU, Battery Management System (BMS) Master, Airbag and Restraint ECU, Industrial Servo Drive, ADAS Sensor Fusion ECU.
Automotive Body Domain Controller
The TC265D40F200WBCKXUMA1's 200 MHz dual-core TriCore CPU and 2.5 MB Flash make it ideal for body domain controllers that consolidate lighting, door, seat, and climate functions. The integrated HSM supports secure boot and OEM key management, while CAN-FD and LIN peripherals connect directly to body-network transceivers without external bridges. AEC-Q100 qualification ensures reliable operation in -40C to +125C automotive environments, and the GTM module can drive PWM-controlled actuators directly.
Recommended
Electric Power Steering (EPS) ECU
EPS ECUs require deterministic torque-loop control and ASIL-D capability, which the TC265D40F200WBCKXUMA1 delivers through its dual-core lockstep TriCore with SMU safety unit. The GTM module generates complementary PWM for the three-phase motor inverter, while the SAR ADC samples phase currents with sub-microsecond latency. Combined with 2.5 MB Flash, the device has ample headroom for sensor-fusion algorithms and OEM diagnostic libraries in a single LQFP-176 footprint.
Recommended
Battery Management System (BMS) Master
The TC265D40F200WBCKXUMA1 suits BMS master controllers that supervise lithium-ion packs up to 800 V. Its CAN-FD interface streams cell telemetry to the vehicle CAN bus, while SPI connects to AFE chips (such as the TLE9012) that monitor individual cells. The on-chip HSM authenticates BMS firmware and protects OEM calibration parameters. Deterministic TriCore interrupt latency ensures cell balancing and SOC/SOH calculations stay within their cycle budgets.
Recommended
Airbag and Restraint ECU
Active-safety airbag systems require ASIL-D capable MCUs, and the TC265D40F200WBCKXUMA1's lockstep TriCore cores with SMU satisfy that integrity level. The dual-core architecture runs the deployment algorithm and watchdog diagnostics in parallel with deterministic loop time. The 2.5 MB Flash stores deployment tables and event-recorder data, while the HSM protects OEM-issued squib keys and prevents unauthorized deployment.
Recommended
Industrial Servo Drive
Outside of automotive, the TC265D40F200WBCKXUMA1 powers industrial servo drives that require deterministic multi-axis PWM and EtherCAT connectivity. The GTM module generates up to 200 MHz resolution PWM for FOC loops on three-phase PMSM motors. TriCore DSP instructions accelerate Clarke/Park transforms and proportional-integral controllers in firmware. The LQFP-176 package supports both control-board and integrated-drive layouts in factory automation.
Recommended
ADAS Sensor Fusion ECU
Sensor-fusion ECUs in advanced driver-assistance systems aggregate radar, lidar, and camera data on a high-throughput platform. The TC265D40F200WBCKXUMA1's dual-core TriCore at 200 MHz runs object-tracking firmware while the second core handles safety monitoring. Multiple CAN-FD nodes and SPI interfaces connect to sensor front-ends, and the HSM authenticates incoming sensor data. The AEC-Q100 qualification and LQFP-176 EP thermal performance suit ADAS ECU enclosures.

Key Differentiators
- Triple-core upgrade path in same LQFP-176-22 footprint (vs TC275D40F200WBCKXUMA1)
- Lower-cost TC264D step-down path shares footprint (vs TC264D40F200WBCKXUMA1)
- Integrated EVITA-Full HSM eliminates external secure element (vs TC233D40F200NBCKXUMA1)
Design Notes
The TC265D40F200WBCKXUMA1 requires a stable 3.3 V or 5 V supply on VEXT and a separate core voltage generated by the internal EVR. Place a 100 nF decoupling cap on each VDD pin and a 4.7 uF bulk capacitor on the EVR input. Use Infineon's TLF35584 PMIC to provide safety-compliant watchdog, supply monitoring, and ASIL-D voltage supervision for chassis and powertrain ECUs.
Estimated: at 200 MHz dual-core full load, the device dissipates approximately 1.5 W to 2 W. The PG-LQFP-176-22 EP package has a thermal resistance of about 25 C/W on a 4-layer JEDEC test board, allowing junction temperature to stay below 125 C at +85 C ambient. The exposed pad must be soldered to a continuous copper pour (recommended at least 4 cm x 4 cm) to meet this thermal performance. Without a proper thermal pad, the junction may exceed AEC-Q100 thermal limits.
Route high-speed signals (CAN-FD, SPI, QSPI, and debug ASC) with 50 ohm controlled impedance and keep trace lengths under 50 mm to avoid signal-integrity issues. Place the 16 MHz crystal within 5 mm of the XTAL pins and guard the crystal traces with a ground ring. Reference Infineon's AURIX PCB Design App Note for the recommended LQFP-176 EP footprint, via stitching, and exposed-pad via pattern.
Do not skip configuration of the SWD/JTAG debug port lock bits in production firmware - leaving the debug interface open allows firmware extraction. Also, ensure the HSM is provisioned with secure boot keys before deploying OTA updateable firmware, otherwise OTA could bypass authentication. Finally, always configure the PMS and SMU to map safety-relevant faults to the error pin so that the external PMIC can shut down the system deterministically.
