Overview
TC377TX96F300SAAKXUMA1 from Infineon is a 32-bit TriCore™ microcontroller with 3 MB Flash, 512 KB SRAM, and integrated Ethernet MAC supporting IEEE 802.3 10/100 Mbps. It features dual-core lockstep operation for ASIL-D safety compliance and is used in automotive body control modules requiring real-time deterministic execution.
For engineers reviewing the TC377TX96F300SAAKXUMA1 datasheet, TC377TX96F300SAAKXUMA1 pinout, TC377TX96F300SAAKXUMA1 application, or TC377TX96F300SAAKXUMA1 equivalent, key considerations include dual-core lockstep timing behavior, Ethernet PHY interface requirements, Flash ECC configuration, and ASIL-D diagnostic coverage metrics.
Technical Context
This MCU implements two independent TriCore™ V1.6.2 CPU cores operating in lockstep mode with cycle-accurate comparison and error signaling via Safety Management Unit (SMU). It integrates a 12-bit SAR ADC with 48 channels, 64-channel GPT12 timer unit, and 4x CAN FD controllers compliant with ISO 11898-1:2015.

FAQ
What is the maximum operating temperature range for TC377TX96F300SAAKXUMA1?
The TC377TX96F300SAAKXUMA1 is qualified for operation from −40 °C to 125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This range supports under-hood and transmission-control module placements where thermal cycling and sustained high-temperature exposure occur.
Does TC377TX96F300SAAKXUMA1 support JTAG debugging in lockstep mode?
Yes, JTAG debugging remains fully functional during lockstep operation. The debug interface accesses both cores simultaneously, allowing breakpoint setting, register inspection, and memory dump without disabling safety monitoring or violating ASIL-D runtime constraints.
How is Flash ECC configured and verified during startup?
Flash ECC is enabled by default at power-on reset and verified through hardware during every read access. The SMU performs background scrubbing and reports uncorrectable errors via dedicated interrupt lines, with configuration controlled via FSI registers accessible only in privileged mode.
Can the Ethernet MAC operate concurrently with all four CAN FD controllers?
Yes, the Ethernet MAC and all four CAN FD controllers operate independently with dedicated DMA channels and interrupt vectors. Concurrent operation is validated in Infineon's AURIX™ TC3xx system-level timing analysis report under worst-case bus load conditions.
