Product details
Overview
TC222L16F133FACKXUMA1 from Infineon is a TriCore™-based automotive microcontroller with single 133 MHz CPU, 1 MB eFlash (ECC-protected), 96 KB RAM (ECC-protected), 96 KB EEPROM emulation, 24-channel 12-bit SAR ADC, and integrated MultiCAN+ with CAN FD support. It targets ASIL-D safety-critical body control modules requiring deterministic real-time execution, fault-tolerant I/O, and secure boot.
For engineers reviewing the TC222L16F133FACKXUMA1 datasheet, TC222L16F133FACKXUMA1 pinout, TC222L16F133FACKXUMA1 application, or TC222L16F133FACKXUMA1 equivalent, key selection criteria include lockstep-ready TriCore™ architecture, TQFP-80 package compatibility, 3.3 V single-supply operation, SENT sensor interface count, and GTM timer module capability for motor control timing.
Technical Context
The TC222L16F133FACKXUMA1 implements a single TriCore™ 1.6E core with DSP extensions and hardware FPU, operating at 133 MHz with clock delay-based lockstep support for ASIL-D compliance. Its safety architecture includes redundant GTM, CCU6, and GPT12 timer modules plus a dedicated Safety Management Unit (SMU) and Safe DMA controller.
It integrates 4x SENT interfaces for high-precision sensor data acquisition, 2x LIN, 4x QSPI, and 3x CAN channels (including CAN FD at up to 5 Mbps), all connected via SRI crossbar and system peripheral bus. The 3.3 V single-supply design eliminates external voltage sequencing complexity while maintaining full functional safety monitoring of supply, clock, and I/O.
