Product details
Overview
TC212L8F133NACKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E CPU core, 133 MHz max clock, 1 MB program flash, 96 KB data flash (EEPROM-emulated), and integrated MultiCAN+ (3 nodes, 128 message objects). It targets automotive safety-critical ECUs requiring ASIL-D compliance, such as electric power steering and brake control units.
For engineers reviewing the TC212L8F133NACKXUMA1 datasheet, TC212L8F133NACKXUMA1 pinout, TC212L8F133NACKXUMA1 application, or TC212L8F133NACKXUMA1 equivalent, key selection criteria include its dual-core lockstep architecture, ECC-protected memories, on-chip SMU for safety monitoring, GTM-based I/O timing autonomy, and QSPI/ASCLIN/SENT peripheral integration for sensor and actuator interfacing in ISO 26262-compliant systems.
Technical Context
The TC212L8F133NACKXUMA1 implements a safety-certified TriCore™ TC1.6E scalar CPU with binary compatibility to TC1.6P, operating up to 133 MHz across –40°C to +125°C. Its lockstepped shadow core performs real-time comparison against the main core, enabling detection of transient faults per ISO 26262 requirements.
It integrates a Safety Management Unit (SMU) that monitors system-level alarms-including ECC errors, watchdog timeouts, and voltage/temperature violations-and triggers safe state transitions. The Memory Test Unit (MTU) supports on-the-fly ECC correction, memory initialization, and MBIST for SRAM and flash during startup and runtime.

FAQ
What is the maximum operating temperature range for TC212L8F133NACKXUMA1?
The TC212L8F133NACKXUMA1 is qualified for operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This range is validated across all functional blocks including CPU, flash, VADC, and CAN modules, with derating applied only for sustained junction temperatures above 150°C as specified in Section 3.4 of the datasheet.
Does TC212L8F133NACKXUMA1 support CAN FD, and what is its maximum data rate?
Yes, the integrated MultiCAN+ module supports CAN FD with bit rates up to 5 Mbit/s in FD mode and 1 Mbit/s in classical CAN mode. It supports flexible data length (up to 64 bytes per frame), automatic protocol switching, and hardware CRC calculation-fully compliant with ISO 11898-1:2015.
How is flash programming and debugging performed on this MCU?
Programming and debugging use the standard 5-pin JTAG (TRST/TCK/TMS/TDI/TDO) or 2-pin DAP interface, both supporting OCDS Level 1. Flash programming is performed via bootloader in BootROM or through debug tools like Lauterbach TRACE32, supporting secure firmware updates with AES-128 encryption and signature verification.
Is external RAM required for typical ASIL-D applications using this microcontroller?
No external RAM is required: the device integrates 88 KB of ECC-protected DSPR, 8 KB PSPR, and 8 KB instruction cache-sufficient for ASIL-D control loops, sensor fusion, and safety monitor stacks. External memory interfaces (e.g., SDRAM) are not implemented on the TC212 derivative, per datasheet Section 2.1 and Table 1-1.
