Overview
TC397QA160F300SBCKXUMA1 from Infineon is a 32-bit TriCore™ AURIX™ microcontroller with 300 MHz CPU clock, 8 MB on-chip flash, 2.5 MB SRAM, and integrated Ethernet MAC supporting 10/100 Mbps operation. It serves as the main safety controller in automotive ADAS domain controllers requiring ASIL-D compliance.
For engineers reviewing the TC397QA160F300SBCKXUMA1 datasheet, TC397QA160F300SBCKXUMA1 pinout, TC397QA160F300SBCKXUMA1 application, or TC397QA160F300SBCKXUMA1 equivalent, key selection criteria include dual-core lockstep capability, hardware-based safety mechanisms (ECC, parity, watchdogs), real-time debug support, and automotive-grade temperature range (–40 °C to 125 °C).
Technical Context
The TC397QA160F300SBCKXUMA1 integrates three independent TriCore™ CPUs (TC1.6P architecture) with configurable lockstep pairing for safety-critical execution. It includes a dedicated Safety Management Unit (SMU) with configurable error injection and fault response logic.
Memory subsystem features ECC-protected flash and SRAM, with memory protection units (MPUs) per core and a centralized memory management unit (MMU) supporting virtual address translation. Peripheral interconnect uses a deterministic, low-latency crossbar switch with priority arbitration.
