Product details
Overview
TC212L8F133NACLXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring a lockstepped TC1.6E CPU core operating at 133 MHz, 1 MB program flash with ECC, 96 KB data flash for EEPROM emulation, and integrated MultiCAN+ (3 nodes, 128 message objects). It targets automotive safety-critical applications including engine control units and brake systems.
For engineers reviewing the TC212L8F133NACLXUMA1 datasheet, TC212L8F133NACLXUMA1 pinout, TC212L8F133NACLXUMA1 application, or TC212L8F133NACLXUMA1 equivalent, key selection criteria include ASIL-D compliance, dual-core lockstep architecture, on-chip EVR, GTM timer subsystem, and CAN FD support in a PG-TQFP-80 package.
Technical Context
This MCU implements a safety-certified dual-core architecture: one TC1.6E scalar CPU and its lockstepped shadow checker core, both running at 133 MHz across -40°C to 125°C. The system includes ECC-protected memories, SMU for alarm management, and MTU for memory initialization and MBIST.
The peripheral set integrates a MultiCAN+ module supporting CAN FD up to 5 Mbit/s, four QSPI channels (master/slave), two ASCLIN interfaces with LIN v2.1 support, and a GTM with TIM/TOM/DTM subsystems for autonomous I/O timing-enabling deterministic real-time control without CPU intervention.
