MPN： TC275T64F200WDCKXUMA1 ✓ 啟用中TC275T64F200WDCKXUMA1 概覽
An AURIX microcontroller (Automotive Realtime Embedded Integrated Processor Unit) is a family of multi-core 32-bit MCUs designed to meet the highest levels of functional safety (ISO 26262 ASIL-D) and information security (EVITA, HSM) in vehicles. Within the broader hierarchy, AURIX sits at the intersection of automotive microcontroller, safety MCU, and powertrain control processor, serving as the silicon backbone for domain and zonal controllers. The TC27xT family specifically targets powertrain, chassis, and advanced driver-assistance systems (ADAS) requiring deterministic interrupt latency, lockstep cores, and hardware security modules.
Key specifications include 200 MHz maximum clock frequency across three TriCore v1.6 cores, 4 MB (4M x 8) of embedded Flash, 472 KB SRAM inclusive of cache, four CAN nodes, multiple LIN and FlexRay interfaces, and a hardware security module. The 1.3 V/5 V supply domain supports both low-voltage logic and 5 V peripheral interfacing without external level shifters. The PG-LQFP-176-22 package includes an exposed thermal pad that lowers junction-to-ambient thermal resistance for high-temperature under-hood operation.
The TC275T64F200WDCKXUMA1 leverages Infineon's lockstep architecture to support ISO 26262 functional safety up to ASIL-D, making it suitable for systems where faults must be detected within a single clock cycle. Compared to single-core MCUs, the three-core TriCore arrangement separates application processing, peripheral control, and safety monitoring tasks, eliminating the need for an external watchdog or companion safety MCU. According to the Infineon AURIX 1G-PSE datasheet, the device is qualified to AEC-Q100 Grade 0 for automotive environments.
Typical applications include engine management ECUs, transmission control units (TCUs), chassis domain controllers, electric vehicle (EV) inverter control, braking and stability systems, and zonal vehicle compute platforms. The combination of CAN FD, FlexRay, and LIN connectivity makes it a strong fit for legacy and modern in-vehicle networking topologies.
When designing with this part, allocate adequate PCB copper under the exposed pad to meet the theta_JA thermal budget; without a minimum 100 mm² copper pour the maximum operating temperature becomes derated. Program Flash in production via the integrated bootloader or via JTAG using an Infineon DAS device. Always validate the AURIX safety case against the latest Infineon application note package.

典型應用
TC275T64F200WDCKXUMA1 適用於 6 應用s: Engine Management ECU, Transmission Control Unit (TCU), ADAS Domain Controller, Electric Vehicle Inverter Control, Braking and Stability Control, Zonal Vehicle Compute.
Engine Management ECU
The TC275T64F200WDCKXUMA1 is purpose-built for engine management ECUs where its 200 MHz TriCore cores execute fuel-injection timing algorithms with cycle times below 5 ms while remaining inside the AEC-Q100 temperature envelope. Its 4 MB Flash holds full AUTOSAR RTE plus production-grade calibration data, and the lockstep core delivers ISO 26262 ASIL-D coverage for emissions-critical decision paths.
推薦
Transmission Control Unit (TCU)
Automatic transmission control uses the TC275T64F200WDCKXUMA1's three TriCore cores to run gear-shift logic, torque-converter modeling, and CAN-FD vehicle bus comms in parallel without processor contention. The 472 KB SRAM caches the gear-ratio lookup tables for sub-millisecond valve-actuator adjustments, while the four CAN nodes connect to engine, hybrid, and chassis domains synchronously.
推薦
ADAS Domain Controller
For ADAS domain controllers, the TC275T64F200WDCKXUMA1 acts as the safety island that monitors the primary SoC and arbitrates fail-safe responses if sensor data deviates from the model. The hardware security module secures V2X message authentication per EVITA, while 472 KB SRAM allows ring-buffer storage of raw radar frames during the ASIL-D lockstep review of ASIL-D-class decisions.
推薦
Electric Vehicle Inverter Control
Traction inverter control depends on the TC275T64F200WDCKXUMA1's deterministic interrupt latency to drive SiC MOSFET gates within 100 ns of rotor-position feedback. The 200 MHz TriCore cores execute field-oriented control loops in 25 microseconds, while the 5 V I/O domain directly interfaces to TLE9180 gate-driver inputs without level shifting - crucial for 800 V battery architectures.
推薦
Braking and Stability Control
Electronic stability control and brake-by-wire ECUs leverage the TC275T64F200WDCKXUMA1's lockstep TriCore pair to compute yaw-rate corrections inside 2 ms sensor-to-actuator loops. The four CAN-FD nodes collect wheel-speed, IMU, and steering-angle inputs simultaneously, while the AEC-Q100 Grade 0 qualification supports under-hood mounting adjacent to brake hydraulics.
推薦
Zonal Vehicle Compute
Modern zonal ECUs consolidate body, lighting, and thermal management into a single controller built around the TC275T64F200WDCKXUMA1 with 4 MB Flash for multiple AUTOSAR stacks. Its CAN-FD, LIN, and FlexRay interfaces aggregate messages from the entire vehicle zone, and the hardware security module handles UDS 0x27 seed-key authentication for OTA flash updates.

主要差異化特點
- Highest Flash density in the LQFP-176 family (對比SAK-TC234LP-32F200N)
- Three TriCore cores versus two on lower-end derivatives (對比SAK-TC233LP-32F200F)
- Faster 200 MHz clock versus 133 MHz on TC213L (對比SAK-TC213L-8F133F)
設計說明
The LQFP-176 exposed pad (EP) must be soldered to a continuous PCB copper plane no smaller than 100 mm² across top and inner layers to achieve the manufacturer's thermal performance. Estimated: with 100 mm² of 1 oz copper on a 4-layer FR-4 board, the junction-to-ambient thermal resistance (theta_JA) drops from approximately 35 C/W to 15 C/W, enabling full 200 MHz operation across the -40C to +150C AEC-Q100 Grade 0 envelope.
The TC275T64F200WDCKXUMA1 has separate 1.3 V core and 5 V I/O supply rails; place a 10 uF ceramic + 100 nF decoupling pair within 5 mm of each VD and VEXT pin, and a single 47 uF bulk tantalum near the regulator output. A common source of PCB prototypes failing power-up is omitting the VDDPSB (standby) rail decoupling, so always include it on the schematic.
Infineon's AURIX family uses non-JTAG debug by default - the DAS (Device Access Server) over ASCIF is required for production programming. Do not assume JTAG-only debug works; populate the ASCIF header on prototype boards for firmware flashing. Additionally, the Flash ECC must be initialized at boot or the device will report spurious single-bit errors during the first 100 power cycles.
