Product details
Overview
TC222S16F133NACKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring a lockstepped TC1.6E CPU core operating at 133 MHz, 1 MB program flash with ECC, 96 KB data flash for EEPROM emulation, and integrated MultiCAN+ (3 nodes, 128 message objects). It targets automotive safety-critical applications including engine control units and brake systems.
For engineers reviewing the TC222S16F133NACKXUMA1 datasheet, TC222S16F133NACKXUMA1 pinout, TC222S16F133NACKXUMA1 application, or TC222S16F133NACKXUMA1 equivalent, key selection criteria include ASIL-D compliance support, dual-core lockstep architecture, on-chip EVR and PLL clock generation, and QSPI/ASCLIN/SENT peripheral integration for sensor and actuator interfacing in real-time powertrain control.
Technical Context
The TC222S16F133NACKXUMA1 implements a safety-optimized TriCore™ architecture with binary compatibility to TC1.6P, incorporating hardware I/O monitoring (IOM), Memory Test Unit (MTU) with ECC and MBIST, and Safety Management Unit (SMU) for alarm handling. Its dual-core lockstep configuration enables continuous comparison of instruction execution between main and shadow cores.
It integrates a 64-bit Cross Bar Interconnect (SRI) for concurrent bus master access, a 32-bit System Peripheral Bus (SPB), and an SFI bridge linking subsystems. The clock generation unit includes a system PLL supporting precise frequency synthesis from external crystal or oscillator inputs, while the embedded voltage regulator (EVR) supplies regulated 1.3 V and 3.3 V domains.

FAQ
What is the maximum ambient temperature rating for TC222S16F133NACKXUMA1?
The device is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40 °C to +125 °C ambient temperature. Junction temperature limits are enforced via on-die thermal sensor and EVR thermal shutdown logic, with derating required above 105 °C ambient depending on PCB copper area and airflow.
Does TC222S16F133NACKXUMA1 support CAN FD frames at 5 Mbit/s?
Yes-the MultiCAN+ module supports CAN FD with bit rates up to 5 Mbit/s in data phase, compliant with ISO 11898-1:2015. Frame arbitration occurs at classic CAN speeds (up to 1 Mbit/s), while payload transfer uses flexible data rate mode with programmable bit timing registers per node.
How is flash programming performed during production programming?
Production programming uses the on-chip bootloader accessed via JTAG or DAP interface, supporting secure flash loading through Infineon's MemTool or third-party tools compliant with AURIX™ Flash Programming Specification. PFLASH and DFLASH are programmed in 256-byte pages with ECC generation enabled automatically.
Is external RAM required for typical ASIL-D application deployment?
No-on-chip memory is sufficient: 88 KB DSPR and 8 KB PSPR provide ample scratchpad space for real-time tasks, while 1 MB PFLASH and 96 KB DFLASH accommodate application code, safety monitor routines, and EEPROM-emulated calibration data without external expansion.
