TC377TX96F300SABLXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with three lockstep-capable TC1.6.2P CPU cores operating up to 300 MHz, 6 MB program flash, 256 KB data flash for EEPROM emulation, and integrated safety features including ECC-protected memories, Safety Management Unit (SMU), and Memory Test Unit (MTU). It targets automotive powertrain and chassis control systems requiring ASIL-D compliance.
For engineers reviewing the TC377TX96F300SABLXUMA1 datasheet, TC377TX96F300SABLXUMA1 pinout, TC377TX96F300SABLXUMA1 application, or TC377TX96F300SABLXUMA1 equivalent, key selection criteria include triple-core lockstep operation, 300 MHz real-time performance, on-chip HSSL and E-Ray interfaces, and hardware security module (HSM) support in select variants.
Technical Context
The TC377TX96F300SABLXUMA1 implements a tri-core TriCore™ architecture with full lockstep shadowing across all three TC1.6.2P CPUs, enabling ASIL-D functional safety certification. Each core integrates a pipelined FPU, dual MAC unit, 32 KB instruction cache, and 16 KB data cache.
It features a 64-bit SRI crossbar interconnect for concurrent CPU–memory–peripheral access, plus dedicated safety peripherals: SMU for alarm monitoring, MTU for memory initialization and MBIST, and IOM for digital I/O integrity checking - all aligned with ISO 26262 requirements.
