Product details
Overview
TC222L16F133NACKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E CPU core operating at up to 133 MHz, 1 MB program flash, 96 KB data flash for EEPROM emulation, and integrated MultiCAN+ (3 nodes, 128 message objects). It targets automotive safety-critical control units requiring ASIL-D compliance.
For engineers reviewing the TC222L16F133NACKXUMA1 datasheet, TC222L16F133NACKXUMA1 pinout, TC222L16F133NACKXUMA1 application, or TC222L16F133NACKXUMA1 equivalent, key selection criteria include its dual-core lockstep architecture, ECC-protected memories, on-chip SMU and MTU for functional safety, and QSPI/ASCLIN/SENT peripheral support for sensor and actuator interfacing in powertrain and chassis systems.
Technical Context
This MCU implements a safety-certified dual-core architecture: one TC1.6E scalar CPU with 88 KB DSPR and 8 KB PSPR, plus a lockstepped shadow core for real-time fault detection. Its memory subsystem includes 1 MB PFLASH and 96 KB DFLASH-both ECC-protected-and boot ROM with secure startup routines.
The peripheral set is optimized for automotive real-time control: MultiCAN+ supports CAN FD at up to 5 Mbps per node; four QSPI channels operate at up to 50 Mbit/s in master/slave mode; two ASCLIN interfaces provide hardware LIN v2.1 and J2602 support; and the GTM delivers autonomous timing, PWM, and signal conditioning without CPU intervention.

FAQ
What is the maximum operating temperature range for TC222L16F133NACKXUMA1?
The TC222L16F133NACKXUMA1 is rated for continuous operation from –40°C to +125°C ambient temperature, validated per AEC-Q100 Grade 1 qualification. This range covers under-hood environments in modern ICE and EV powertrain applications where junction temperatures may reach 150°C under worst-case thermal conditions.
Does TC222L16F133NACKXUMA1 support CAN FD, and what is the maximum bit rate?
Yes, it integrates a MultiCAN+ module supporting CAN FD with programmable bit rates up to 5 Mbps on each of its three independent CAN nodes. The controller handles both classic CAN and CAN FD frames-including flexible data-length payloads-without CPU intervention via hardware message object arbitration and FIFO buffering.
How is functional safety (ASIL-D) implemented in this microcontroller?
ASIL-D compliance is achieved through hardware-enforced redundancy: lockstep CPU cores with real-time comparison, ECC on all memories (PFLASH, DFLASH, SRAM), SMU-managed alarm routing, MTU for memory self-test, and IOM for digital I/O monitoring. These features are certified per ISO 26262-5/6 and supported by Infineon's safety manual and FMEDA reports.
What debug interfaces does TC222L16F133NACKXUMA1 provide?
It supports both IEEE 1149.1-compliant 5-wire JTAG and ARM CoreSight-compatible Device Access Port (DAP) for OCDS Level 1 debug. These interfaces enable full visibility into CPU registers, DMA transfers, and on-chip bus transactions during development, validation, and field diagnostics-without requiring external debug probes beyond standard SWD/JTAG adapters.
