Product details
Overview
TC275TP64F200WDCLXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with three CPU cores: two high-performance TC1.6P (200 MHz) and one power-efficient TC1.6E (200 MHz), 4 MB PFlash, 384 KB DFlash, ECC-protected memories, and integrated Safety Management Unit (SMU). It targets automotive ASIL-D safety-critical applications including engine control, transmission, and battery management systems.
For engineers reviewing the TC275TP64F200WDCLXUMA1 datasheet, TC275TP64F200WDCLXUMA1 pinout, TC275TP64F200WDCLXUMA1 application, or TC275TP64F200WDCLXUMA1 equivalent, key selection considerations include dual-lockstep core support, 64-channel DMA with safety monitoring, ERAY and Ethernet interfaces, and hardware security module (HSM) availability in select variants.
Technical Context
The TC275TP64F200WDCLXUMA1 implements a triple-core TriCore architecture with two lockstepped TC1.6P cores for functional safety and one independent TC1.6E core for background tasks. All cores operate up to 200 MHz across -40°C to 125°C ambient temperature and feature integrated FPU, MAC units, and scratchpad RAM (up to 120 KB DSPR per TC1.6P).
It integrates safety-critical subsystems including SMU, MTU (memory test unit with ECC/MBIST), IOM (I/O monitor), and optional HSM. Peripheral connectivity includes four ASCLIN channels with LIN v2.1 support, ERAY controller, 10/100 Ethernet MAC, QSPI, and 5 V-tolerant I/O with configurable pull-up/down reset behavior.

Applications
| Engine Control Unit (ECU) | Electric Power Steering (EPS) |
|---|---|
|
Use Scenario: Real-time combustion timing, fuel injection, and knock detection in gasoline/diesel engines. IC Role / Device Role / Timing Role: Primary safety-critical controller executing ASIL-D software partitions with lockstep core validation. Use Value: Deterministic 200 MHz execution, ECC memory, and SMU enable ISO 26262-compliant fault detection within <50 µs latency. |
Use Scenario: Torque assist calculation, motor position feedback, and fail-safe torque reduction during steering actuation. IC Role / Device Role / Timing Role: Dual-lockstep TC1.6P cores manage safety-critical torque path; TC1.6E handles CAN/LIN gateway functions. Use Value: Integrated ERAY and ASCLIN support multi-bus vehicle networking while maintaining ASIL-D diagnostic coverage. |
| Battery Management System (BMS) | Advanced Driver Assistance (ADAS) Domain Controller |
|
Use Scenario: Cell voltage/temperature monitoring, SOC/SOH estimation, and contactor control in high-voltage traction batteries. IC Role / Device Role / Timing Role: Safety monitor for isolation barriers and HV interlock circuits using IOM and SMU-triggered safe states. Use Value: DFlash-based EEPROM emulation stores calibration data with wear leveling; ECC prevents silent corruption of critical BMS parameters. |
Use Scenario: Sensor fusion preprocessing (radar/camera inputs), path planning, and actuator command arbitration in L2+ systems. IC Role / Device Role / Timing Role: High-bandwidth SRI bus enables concurrent access to PFlash, DFlash, and DMA buffers for real-time data streaming. Use Value: 64-channel DMA with scatter-gather and safety-checking transfers offloads CPU from sensor data movement, reducing jitter. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar tri-core automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC277TP128F200NDCXUMA1 | BGA292 package, 128 KB RAM per core, 8 MB PFlash, adds PCIe interface and enhanced HSM | Targeted at domain controllers requiring higher bandwidth and cryptographic acceleration | Select when PCIe host capability or >4 MB flash is required; not pin-compatible with LQFP-176 |
| TC234LP32F200NACXUMA1 | Dual-core (TC1.6P + TC1.6E), 2 MB PFlash, 200 MHz, LQFP-144, no Ethernet or ERAY | Cost-optimized ECU for ASIL-B/C applications without deterministic networking | Choose for non-networked body control modules where Ethernet/ERAY are unnecessary and footprint is constrained |
Compared with TC275TP64F200WDCLXUMA1, TC277 offers higher memory and PCIe but requires BGA rework, while TC234 reduces cost and complexity at the expense of safety networking and flash capacity - making TC275 the balanced choice for ASIL-D ECU designs needing ERAY/Ethernet in LQFP form.

FAQ
What is the maximum operating frequency and temperature range for TC275TP64F200WDCLXUMA1?
The TC275TP64F200WDCLXUMA1 operates at up to 200 MHz across the full industrial temperature range of -40°C to +125°C ambient. This rating is validated per AEC-Q100 Grade 1 and includes derating margins for sustained operation under thermal stress in engine bay environments.
Does TC275TP64F200WDCLXUMA1 include hardware support for AUTOSAR OS and MCAL drivers?
Yes - Infineon provides certified AUTOSAR Basic Software (BSW) modules including MCAL drivers for ASCLIN, ETH, ERAY, DADC, and SMU, fully compatible with TC275TP64F200WDCLXUMA1's register map and safety mechanisms per AUTOSAR 4.3 specification.
How is functional safety (ASIL-D) implemented in this microcontroller?
ASIL-D compliance is achieved through hardware-enforced redundancy: lockstep CPU pairs, ECC on all memories, SMU-monitored clock/reset domains, IOM for I/O integrity, and MTU for periodic memory self-tests - all documented in Infineon's FMEDA report and ISO 26262 TÜV-certified safety manual.
Is the Hardware Security Module (HSM) included in TC275TP64F200WDCLXUMA1?
No - the HSM is not integrated into TC275TP64F200WDCLXUMA1. It is available only in selected TC277 variants (e.g., TC277TP128F200NDCXUMA1). This part relies on software-based crypto libraries and secure boot via BROM with SHA-256 signature verification.
