It targets automotive powertrain and chassis control systems requiring functional safety up to ISO 26262 ASIL-D.
For engineers reviewing the SAK-TC297TX-128F300N BC datasheet, SAK-TC297TX-128F300N BC pinout, SAK-TC297TX-128F300N BC application, or SAK-TC297TX-128F300N BC equivalent, this page delivers verified technical context, BGA292 package mapping, real-time safety features, and automotive-grade timing/performance specifications - all validated against Infineon's official BC-step data sheet (V1.1, 2019-03).
Technical Context
The TC297X implements a triple-core architecture: two independent 300 MHz TriCore™ TC1.6P CPUs plus a lockstepped shadow core for fault detection, supporting time-triggered execution and hardware-based safety monitoring. Its SRI crossbar enables concurrent 64-bit bus access between CPUs, DMA, and memory subsystems.
On-chip memory includes 8 MB program flash with ECC and write-protection, 768 KB data flash for EEPROM emulation, and 32 KB LMU for secure boot and key storage. All peripherals-including ETH, E-Ray, ASCLIN, QSPI, and VADC-feature dedicated safety monitors and error-correcting interfaces aligned with AUTOSAR MCAL requirements.
