Product details
Overview
TC224L16F133FACLXUMA1 from Infineon is a TriCore™-based AURIX™ automotive microcontroller with single 133 MHz CPU, 1 MB ECC-protected flash, 96 KB ECC-protected RAM, 24-channel 12-bit SAR ADC, and integrated GTM timer module. It supports ASIL-D safety systems via diverse lockstep architecture and operates in -40°C to +125°C range in TQFP-144 package for engine control units.
For engineers reviewing the TC224L16F133FACLXUMA1 datasheet, TC224L16F133FACLXUMA1 pinout, TC224L16F133FACLXUMA1 application, or TC224L16F133FACLXUMA1 equivalent, key selection criteria include CAN FD interface count, GTM timing resolution, EEPROM emulation endurance (125 k cycles), and dual-voltage domain support for functional safety partitioning.
Technical Context
This MCU implements a single TriCore™ 1.6E core with DSP extensions and hardware FPU, paired with a dedicated safety management unit (SMU) and redundant clock monitoring. Its GTM provides programmable time-triggered I/O, while MultiCAN+ includes three CAN FD controllers supporting data rates up to 5 Mbit/s.
The device uses a unified 3.3 V supply with internal voltage regulation and integrates BROM for boot code, SDMA for safe data movement, and OCDS for on-chip debug security. All memory blocks feature ECC protection, and I/Os support configurable access permissions per safety zone.

FAQ
What is the maximum operating temperature for TC224L16F133FACLXUMA1?
The device is qualified for operation from -40°C to +125°C ambient temperature, with extended hot-package variants available up to +150°C junction temperature upon request. Thermal derating curves and PCB layout guidelines for thermal management are provided in Application Note AN2018-09.
Does TC224L16F133FACLXUMA1 support AUTOSAR OS and MCAL?
Yes - it is fully supported by Infineon's AURIX™ Development Studio v7.0+ with certified AUTOSAR 4.3 MCAL drivers, including CAN FD, ADC, GTM, and DIO modules. Pre-certified SafeRTOS and FreeRTOS BSPs are also available for ASIL-B integration.
How is EEPROM emulation implemented in this MCU?
It uses 96 KB of dedicated data flash memory with built-in wear-leveling firmware and 125,000 guaranteed write/erase cycles. The emulation layer maps logical EEPROM addresses to physical flash sectors and handles sector swapping transparently during runtime.
Can TC224L16F133FACLXUMA1 be used without external crystal?
No - an external 1–20 MHz crystal is mandatory for ASIL-D compliance, as the internal RC oscillator lacks sufficient accuracy and stability for safety-critical clock monitoring. The XTALIN/XTALOUT pins must be connected to a crystal with load capacitance matching the 12 pF specification.
