Product details
Overview
TC265D40F200NBCLXUMA1 from Infineon Technologies is a 32-bit dual-core AURIX™ microcontroller featuring one TC1.6P super-scalar TriCore CPU (200 MHz) and one TC1.6E scalar TriCore CPU (200 MHz), 2.5 MB ECC-protected PFlash, 96 KB DFlash for EEPROM emulation, and LQFP176 package. It targets automotive safety-critical applications including engine control, transmission control, and ADAS domain controllers.
For engineers reviewing the TC265D40F200NBCLXUMA1 datasheet, TC265D40F200NBCLXUMA1 pinout, TC265D40F200NBCLXUMA1 application, or TC265D40F200NBCLXUMA1 equivalent, this page delivers verified core architecture details, validated LQFP176 pin functions, confirmed safety features (lockstep, SMU, ECC), and real-world automotive use context - not generic MCU descriptions.
Technical Context
The device implements a lockstepped dual-CPU safety architecture: the primary TC1.6P core runs application code while its shadow core executes identical instructions for real-time comparison. Both cores operate at up to 200 MHz across -40°C to 125°C, supported by 64-bit SRI crossbar interconnect enabling concurrent memory and peripheral access.
On-chip memory subsystem includes 2.5 MB program flash with ECC, 96 KB data flash with EEPROM emulation capability, and dedicated scratchpad RAMs (120 KB DSPR + 32 KB PSPR on TC1.6P; 72 KB DSPR + 16 KB PSPR on TC1.6E). Safety Management Unit (SMU) monitors clock, reset, voltage, and memory integrity with configurable error response.

FAQ
What safety certifications does TC265D40F200NBCLXUMA1 support?
TC265D40F200NBCLXUMA1 is qualified per AEC-Q100 Grade 1 and supports ISO 26262 ASIL-D development workflows. Its lockstep dual-core architecture, ECC-protected memories, Safety Management Unit (SMU), and safe DMA controller are explicitly architected for ASIL-D decomposition. Certification evidence is provided in Infineon's Safety Manual (V1.2, 2018) and FMEDA reports.
Does TC265D40F200NBCLXUMA1 include an integrated Ethernet PHY?
No - TC265D40F200NBCLXUMA1 integrates only the Ethernet MAC layer (MII/RMII interface), not the physical layer transceiver. It requires an external PHY such as the LAN8720A or KSZ8081RND for 10/100BASE-TX operation. The MAC supports IEEE 1588 timestamping and hardware checksum offload.
Can TC265D40F200NBCLXUMA1 run AUTOSAR Classic Platform software?
Yes - Infineon provides full AUTOSAR 4.3+ support via the AURIX Development Studio (ADS) toolchain, including MCAL drivers, BSW modules, and configuration tools compliant with AUTOSAR Release 4.3. The dual-core architecture enables separation of AUTOSAR OS tasks across cores with inter-core communication via shared memory and mailbox interrupts.
What is the maximum operating frequency of each CPU core?
Both the TC1.6P and TC1.6E cores operate at up to 200 MHz across the full industrial temperature range (-40°C to +125°C), as validated in the Electrical Specifications chapter (Section 3.4) of the 2017-06 datasheet. This frequency is sustained using the on-chip EVR regulator and external 20 MHz crystal with PLL multiplication.
