Overview
TC275TP64F200WCAKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three CPU cores (two TC1.6P super-scalar and one TC1.6E scalar), 200 MHz max clock frequency, 4 MB embedded PFlash with ECC, 384 KB DFlash for EEPROM emulation, and integrated Safety Management Unit (SMU) for ASIL-D automotive safety compliance. It targets engine control units, transmission control, and battery management systems requiring real-time deterministic execution and functional safety.
For engineers reviewing the TC275TP64F200WCAKXUMA1 datasheet, TC275TP64F200WCAKXUMA1 pinout, TC275TP64F200WCAKXUMA1 application, or TC275TP64F200WCAKXUMA1 equivalent, key selection criteria include triple-core lockstep capability, on-chip HSM support, 64-channel DMA with safe transfer, ERAY and Ethernet interface timing, and LQFP176 package compatibility with automotive-grade thermal and ESD robustness.
Technical Context
The TC275TP64F200WCAKXUMA1 implements a heterogeneous multi-core architecture: two high-performance TC1.6P cores operate at up to 200 MHz with dual MAC/FPU pipelines and 16 KB ICACHE/8 KB DCACHE, while the TC1.6E core provides binary-compatible low-power execution. All cores feature lockstepped shadow pairs for ASIL-D fault detection.
Its memory subsystem includes 4 MB ECC-protected PFlash, 384 KB DFlash with wear-leveling support, 32 KB LMU, and scratchpad RAMs (up to 120 KB DSPR total). Peripheral integration includes four ASCLIN channels with LIN v2.1, ERAY controller, 10/100 Ethernet MAC, and hardware I/O Monitor (IOM) for pin-level safety checking.

FAQ
What is the maximum operating temperature for TC275TP64F200WCAKXUMA1?
The TC275TP64F200WCAKXUMA1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from −40°C to +125°C ambient temperature. Its thermal design includes an exposed pad for PCB heat sinking and internal thermal monitoring via the integrated temperature sensor (±2°C accuracy), enabling dynamic clock throttling if junction temperature exceeds 150°C.
Does TC275TP64F200WCAKXUMA1 support secure boot and cryptographic operations?
Yes-when configured with the optional Hardware Security Module (HSM), it supports secure boot with SHA-256 hash verification, AES-128/256 encryption/decryption, RSA-2048 signature validation, and true random number generation. The HSM operates independently of the main TriCore CPUs and isolates keys in tamper-resistant memory.
How does the ERAY interface differ from CAN FD in TC275TP64F200WCAKXUMA1?
The ERAY controller implements the FlexRay protocol (ISO 17458), offering deterministic time-triggered communication with configurable static/dynamic segments, up to 10 Mbit/s data rate, and built-in fault-tolerant dual-channel operation. Unlike CAN FD's event-triggered arbitration, ERAY guarantees bounded latency and synchronized node startup-critical for x-by-wire and active suspension systems.
Can TC275TP64F200WCAKXUMA1 be used without the Hardware Security Module (HSM)?
Yes-the HSM is an optional silicon feature; TC275TP64F200WCAKXUMA1 functions fully without it, supporting standard boot modes, Flash programming, and all peripheral interfaces. However, ASIL-D safety goals requiring secure boot, encrypted firmware updates, or runtime attestation require HSM-enabled variants (e.g., TC275TP64F200WCAKXUMA1 with HSM option enabled in mask ROM).
