Product details
Overview
TC3E7QX192F300SAAKXUMA1 from Infineon is a 32-bit AURIX™ TC3xx multicore microcontroller based on the TriCore™ v2.0 architecture, featuring three independent TriCore CPU cores (up to 300 MHz), 1.5 MB on-chip Flash with ECC, 256 KB SRAM with parity, and integrated safety mechanisms including lockstep core pairs and hardware-based memory BIST. It targets automotive ASIL-D safety-critical control units such as electric power steering (EPS) and brake-by-wire systems.
For engineers reviewing the TC3E7QX192F300SAAKXUMA1 datasheet, TC3E7QX192F300SAAKXUMA1 pinout, TC3E7QX192F300SAAKXUMA1 application, or TC3E7QX192F300SAAKXUMA1 equivalent, key selection criteria include ASIL-D compliance, dual-core lockstep capability, 300 MHz real-time performance, integrated HSM for secure boot, and support for AUTOSAR 4.x and SafeTcore runtime.
Technical Context
This device implements a heterogeneous multicore architecture with two main TriCore CPUs (TC1.6.2 and TC1.6.2P) plus a dedicated safety co-processor (SCU), all operating under ISO 26262-compliant safety monitoring. It integrates a Peripheral Server Unit (PSU) for deterministic I/O handling and supports up to 128-channel GPT12 timer subsystems with capture/compare and PWM generation.
The memory subsystem includes 1.5 MB of Flash organized in two banks (for safe firmware updates), 256 KB of SRAM split across multiple domains (including safety-critical RAM with parity), and a 16 KB instruction cache with lockable sections. Safety features include LBIST/MBIST, end-to-end data path protection, and configurable error correction codes (ECC) for Flash and parity for SRAM.
