Product details
Overview
TC224S16F133FABKXUMA1 from Infineon is a TriCore™-based AURIX™ automotive microcontroller with dual-lockstep 133 MHz CPU, 1 MB ECC-protected eFlash, 96 KB EEPROM-emulated data flash (125 k write cycles), 96 KB ECC-protected SRAM, and integrated MultiCAN+ with CAN FD support - deployed in ASIL-D–compliant powertrain control units.
For engineers reviewing the TC224S16F133FABKXUMA1 datasheet, TC224S16F133FABKXUMA1 pinout, TC224S16F133FABKXUMA1 application, or TC224S16F133FABKXUMA1 equivalent, key selection criteria include lockstep timing divergence tolerance, GTM timer resolution for motor phase alignment, SENT interface channel count for sensor fusion, and single 3.3 V supply compatibility with automotive domain controller power architectures.
Technical Context
The device implements two independent TriCore™ 1.6E CPUs in diverse lockstep configuration with clock delay injection to detect transient faults, enabling ISO 26262 ASIL-D fault coverage without external safety monitors. Its Generic Timer Module (GTM) provides hardware-accelerated PWM generation, time-triggered I/O, and position capture with sub-microsecond jitter.
MultiCAN+ includes three CAN FD controllers supporting simultaneous 5 Mbps data phase and 1 Mbps arbitration, while the 24-channel 12-bit SAR ADC features configurable sampling windows synchronized to GTM events for real-time torque estimation in electric drive inverters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ASIL-D automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC234L32F200FABKXUMA1 | 200 MHz dual-core, 2 MB flash, TQFP-176 package - higher performance but larger footprint and 0.15 W higher active power | Required for complex sensor fusion stacks exceeding 1.2 MIPS real-time budget; not drop-in compatible due to pin count and thermal pad layout | Select when >180 µs worst-case interrupt latency must be guaranteed under full AUTOSAR BSW load |
| TC222S16F133FABKXUMA1 | TQFP-80 package, identical core/peripheral spec but reduced I/O count (64 vs. 100 GPIO) and no GTM_TOM12–15 outputs | Suitable for compact body control modules where space constraints preclude TQFP-144; lacks full motor control PWM channel set | Choose for cost-sensitive chassis modules requiring only 4 CAN FD channels and ≤12 PWM outputs |
Compared with TC224S16F133FABKXUMA1, the TC234 offers higher compute headroom at the cost of board area and thermal design complexity, while the TC222 trades I/O density and GTM scalability for smaller form factor - all share identical safety architecture and AUTOSAR compatibility.

FAQ
What is the maximum ambient temperature rating for TC224S16F133FABKXUMA1 in continuous operation?
The device is qualified for continuous operation from –40 °C to +125 °C ambient temperature per AEC-Q100 Grade 1. Hot package variants supporting Ta = +150 °C are available on request but require custom qualification and are not standard stock items.
Does TC224S16F133FABKXUMA1 support AUTOSAR 4.3 or later versions?
Infineon provides AUTOSAR Basic Software (BSW) modules certified for AUTOSAR 4.2.1 and 4.3 through its AURIX Development Studio toolchain. Full AUTOSAR 4.4+ compliance requires customer-integrated MCAL updates aligned with specific compiler and OS configurations.
How many SENT interfaces are physically implemented on this part?
TC224S16F133FABKXUMA1 integrates 16 dedicated SENT receiver channels mapped to pins SENT0 through SENT15. Each channel supports standard SENT frame formats (single/dual nibble, fast/slow channel) with programmable pulse-width thresholds and CRC validation.
Is external flash required for boot code storage?
No. The device contains 1 MB of on-chip eFlash with ECC protection, sufficient to store boot code, application firmware, and safety monitor routines. Boot ROM (BROM) provides secure boot loader functionality with hash-based authentication and encrypted image loading capability.
