Product details
Overview
TC299TP128F300SBBKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P CPU cores, lockstep shadow core for ASIL-D compliance, 8 MB program flash (ECC-protected), 768 KB data flash for EEPROM emulation, and integrated 128-channel DMA. It targets automotive safety-critical ECUs such as electric power steering and brake control systems.
For engineers reviewing the TC299TP128F300SBBKXUMA1 datasheet, TC299TP128F300SBBKXUMA1 pinout, TC299TP128F300SBBKXUMA1 application, or TC299TP128F300SBBKXUMA1 equivalent, key selection criteria include ASIL-D functional safety certification, dual-core lockstep architecture, on-chip Ethernet (10/100 Mbit/s), E-Ray high-speed deterministic bus, and hardware-based memory protection unit (MPU) with ECC across all embedded memories.
Technical Context
The TC299TP128F300SBBKXUMA1 implements a triple-core architecture: two independent 300 MHz TriCore™ TC1.6P CPUs plus a dedicated lockstepped shadow core for real-time fault detection. Its SRI crossbar interconnect enables concurrent 64-bit access between CPUs, DMA, and memory subsystems.
It integrates safety-critical peripherals including ASIL-D-certified Ethernet MAC (MII/RMII), dual E-Ray controllers (up to 10 Mbit/s), 12x CAN FD nodes, and hardware-accelerated cryptographic engine supporting AES-128/256, SHA-256, and RSA-2048 - all with end-to-end ECC protection and lockstep monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC297TP128F300SBBKXUMA1 | Same core architecture but BGA416 package (416 pins), reduced peripheral set: no Ethernet MAC, only single E-Ray channel. | Suitable for cost-sensitive ASIL-B/C applications like HVAC or body control where Ethernet/E-Ray bandwidth is not required. | Select when system-level I/O count and safety level allow reduction in pin count and feature set to lower BOM cost. |
| S32K344WAT0VLQY | NXP S32K3 series with Arm Cortex-M7 dual-core lockstep, 4 MB flash, no integrated Ethernet PHY interface, different safety library certification scope. | Targeted at chassis and powertrain applications with strong CAN FD focus but less emphasis on time-triggered Ethernet determinism. | Choose when leveraging NXP's S32 Design Studio ecosystem and existing Arm toolchain integration outweighs AURIX-specific features. |
Compared with TC299TP128F300SBBKXUMA1, the TC297 variant reduces footprint and cost by removing Ethernet and one E-Ray channel, while the S32K344 offers Arm-based toolchain familiarity but lacks native time-triggered Ethernet scheduling and AURIX's mature ASIL-D safety case documentation.

Does this MCU support AUTOSAR Classic and Adaptive platforms?
Yes - the TC299TP128F300SBBKXUMA1 is fully supported in AUTOSAR Classic R4.x releases via Infineon's AURIX Development Studio and MCAL drivers. For AUTOSAR Adaptive, it supports POSIX-compliant OS environments through its Linux-capable Ethernet interface and hardware virtualization extensions, enabling containerized middleware deployment with time-triggered scheduling guarantees.
What is the maximum operating temperature and qualification standard?
The TC299TP128F300SBBKXUMA1 is qualified to AEC-Q100 Grade 1, supporting continuous operation from –40 °C to +125 °C ambient temperature. Junction temperature limits are defined in the datasheet Section 3.4, with thermal derating applied above 105 °C ambient depending on PCB layout and airflow. The BGA516 package includes an exposed thermal pad for direct heatsink attachment in high-power ECU designs.
