Product details
Overview
TC222S16F133FABKXUMA1 from Infineon is a TriCore™-based AURIX™ microcontroller for ASIL-D automotive safety systems, featuring a 133 MHz lockstep-capable CPU core, 1 MB eFlash with ECC, 96 KB RAM with ECC, 24-channel 12-bit SAR ADC, and integrated CAN FD (3 channels), QSPI (4), LIN (2), and SENT (4) interfaces. It targets engine control units, battery management systems, and ADAS domain controllers requiring deterministic real-time execution and fault containment.
For engineers reviewing the TC222S133FABKXUMA1 datasheet, TC222S16F133FABKXUMA1 pinout, TC222S16F133FABKXUMA1 application, or TC222S16F133FABKXUMA1 equivalent, key selection criteria include ASIL-D compliance via diverse lockstep architecture, single 3.3 V supply operation, TQFP-80 package footprint, GTM timer subsystem capability, and EEPROM-emulated data flash endurance of 125 k write cycles.
Technical Context
The TC222S16F133FABKXUMA1 implements a dual-core TriCore™ architecture with one main core and one lockstep monitor core using clock delay diversity to detect transient faults. Its GTM module provides hardware-accelerated timing, PWM generation, and signal conditioning independent of CPU load.
It integrates MultiCAN+ with CAN FD support up to 5 Mbps, four QSPI interfaces for external flash expansion, and a Safety Management Unit (SMU) that monitors voltage, clock, memory integrity (ECC), and I/O access permissions - all aligned with ISO 26262 ASIL-D requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ASIL-D microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC234L32F200NACXUMA1 | Higher clock (200 MHz), larger package (TQFP-144), 2 MB flash, 320 KB RAM - adds performance headroom but increases PCB area and BOM cost. | Targeted at multi-domain controllers requiring concurrent AUTOSAR OS partitions and higher computational throughput. | Select when >133 MHz CPU performance or >1 MB flash is required; not drop-in due to pin count and thermal design differences. |
| TC223L16F133FABKXUMA1 | Same core, frequency, and memory specs but in TQFP-100 package - offers additional GPIOs and CAN/LIN channels vs. TQFP-80 variant. | Better suited for applications needing more sensor interfaces or expanded communication routing without changing software architecture. | Choose for enhanced I/O flexibility where board space permits larger footprint; identical software compatibility and safety certification. |
Compared with TC222S16F133FABKXUMA1, the TC223L variant adds I/O without increasing core complexity, while the TC234L delivers higher performance at the cost of larger footprint and thermal management overhead - making the TC222S optimal for cost- and space-constrained ASIL-D ECU designs.

FAQ
What is the maximum junction temperature rating for TC222S16F133FABKXUMA1?
The device is qualified for operation from −40 °C to +125 °C ambient temperature, with a maximum junction temperature of +150 °C under specified thermal conditions. This rating is validated per AEC-Q100 Grade 1 requirements and applies to the TQFP-80 package with standard PCB copper pour and airflow.
Does TC222S16F133FABKXUMA1 support AUTOSAR 4.3 or later?
Yes - Infineon provides AUTOSAR Basic Software (BSW) modules compliant with AUTOSAR 4.2 and 4.3 for the TC22xL(S) family, including MCAL drivers for CAN FD, ADC, GTM, and Flash EEPROM emulation. Full 4.3+ support requires use of Infineon's AURIX Development Studio v7.0 or later toolchain.
Is external watchdog required when using the internal safety watchdog (WDT)?
No - the integrated Windowed Watchdog Timer (WWDT) meets ASIL-D requirements when configured with appropriate timeout windows and monitored by the Safety Management Unit. External watchdogs are optional for layered safety architectures but not mandatory for functional safety compliance.
Can TC222S16F133FABKXUMA1 operate with only a 3.3 V supply, or are auxiliary voltages needed?
Yes - it operates exclusively from a single 3.3 V supply rail. All internal regulators (including analog LDOs for ADC and PLL) are integrated. No external 5 V, 1.2 V, or other auxiliary supplies are required, reducing bill-of-materials and simplifying power design.
