Product details
Overview
TC264DA40F200WBCKXUMA1 from Infineon Technologies is a 32-bit dual-core AURIX™ microcontroller featuring one high-performance TriCore™ TC1.6P CPU (up to 200 MHz) and one power-efficient TC1.6E CPU, 2.5 MB ECC-protected program flash, 96 KB data flash for EEPROM emulation, and integrated Safety Management Unit (SMU). It targets automotive safety-critical applications including electric powertrain control and ADAS domain controllers.
For engineers reviewing the TC264DA40F200WBCKXUMA1 datasheet, TC264DA40F200WBCKXUMA1 pinout, TC264DA40F200WBCKXUMA1 application, or TC264DA40F200WBCKXUMA1 equivalent, this device requires attention to lockstep core configuration, ERAY/ETH interface timing, SMU fault response behavior, and LQFP144 thermal derating under ASIL-D system constraints.
Technical Context
The TC264DA40F200WBCKXUMA1 implements a dual-CPU architecture with hardware-enforced lockstep between the TC1.6P and its shadow core for ASIL-D compliance. Its SRI crossbar enables concurrent access to PFLASH, DFLASH, and DSPR/SPSR memories across both cores and DMA channels.
It integrates safety-critical peripherals including ERAY (flexible time-triggered communication), Ethernet MAC (10/100 Mbit/s), and multiple ASCLIN/QSPI interfaces-all monitored by the SMU with configurable error injection and fail-safe state machine transitions.

FAQ
What is the maximum operating frequency of each CPU core in the TC264DA40F200WBCKXUMA1?
The TC264DA40F200WBCKXUMA1 features two TriCore CPUs: the TC1.6P core operates at up to 200 MHz across the full −40 °C to +125 °C temperature range, and the TC1.6E core also runs at up to 200 MHz with identical timing specifications but optimized for lower dynamic power consumption.
Does the TC264DA40F200WBCKXUMA1 support hardware encryption acceleration?
Yes-it includes a dedicated cryptographic hardware accelerator supporting AES-128 (ECB/CBC/CTR modes), SHA-256, and ECDSA signature generation/verification. These functions operate independently of the CPU cores and are accessible via the HSM (Hardware Security Module) interface with protected key storage in BROM.
How is functional safety compliance achieved in this microcontroller?
Functional safety is implemented through hardware lockstep core monitoring, ECC on all memories, SMU-managed fault injection and response, CPU self-tests (e.g., BIST on caches), and dedicated safety pins (ESR0–ESR3). All mechanisms are certified per ISO 26262 ASIL-D at the chip level by TÜV SÜD.
Can the TC264DA40F200WBCKXUMA1 be used in non-automotive applications?
While qualified per AEC-Q100 Grade 1 and architected for automotive ASIL-D use cases, the device may be deployed in industrial safety systems (IEC 61508 SIL3) or aerospace avionics (DO-254) where its lockstep cores, ECC memory, and SMU meet required fault coverage thresholds-but full qualification requires end-application-specific validation.
