Overview
TC299TX128F300NBCKXUMA1 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 (PFLASH), 768 KB data flash (DFLASH) with EEPROM emulation, and integrated 128-channel DMA. It targets automotive safety-critical applications including electric powertrain control and ADAS domain controllers.
For engineers reviewing the TC299TX128F300NBCKXUMA1 datasheet, TC299TX128F300NBCKXUMA1 pinout, TC299TX128F300NBCKXUMA1 application, or TC299TX128F300NBCKXUMA1 equivalent, key selection criteria include ASIL-D functional safety certification, dual-core lockstep architecture, on-chip ECC-protected memory hierarchy, and support for Ethernet (10/100 Mbit/s), E-Ray, and multiple CAN FD interfaces.
Technical Context
The TC299TX128F300NBCKXUMA1 implements a deterministic real-time architecture with two independent TriCore™ TC1.6P superscalar CPUs operating at up to 300 MHz across full industrial temperature range (–40 °C to 125 °C), each backed by dedicated instruction/data scratchpad RAM (up to 32 KB PSPR + 120 KB DSPR), cache (16 KB ICACHE / 8 KB DCACHE), and hardware floating-point units. The lockstepped shadow core provides continuous comparison and error detection per instruction cycle.
Its memory subsystem includes 8 MB of embedded PFLASH with 128-bit wide access, 768 KB DFLASH with wear-leveling and EEPROM emulation capability, and ECC protection across all SRAM, Flash, and cache resources. Safety mechanisms include end-to-end data path protection, memory built-in self-test (MBIST), and configurable watchdog timers with separate clock domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC297T128F300NACKXUMA1 | Same core architecture but BGA416 package (416-pin vs 516-pin); reduced peripheral count (no second Ethernet MAC, fewer CAN FD channels). | Targeted at cost-sensitive ASIL-B/C applications where full TC299 feature set is unnecessary. | Select when footprint, thermal budget, or BOM cost constraints preclude BGA516; verify peripheral mapping against design requirements. |
| S32K344UAT0VLQY | NXP S32K3 series ARM Cortex-R52 dual-core MCU; 320 MHz, 4 MB flash, ASIL-D certified, but lacks native E-Ray and has single Ethernet MAC. | Preferred in designs requiring AUTOSAR Adaptive support or NXP ecosystem integration over TriCore toolchain dependencies. | Choose when leveraging existing NXP software stack or requiring ARM-based functional safety partitioning; note different debug and flash programming infrastructure. |
Compared with TC297T128F300NACKXUMA1, the TC299TX128F300NBCKXUMA1 delivers higher I/O density, dual Ethernet, and full E-Ray support for central domain control; versus S32K344, it offers superior deterministic real-time performance via TriCore architecture and native time-triggered networking, critical for safety-critical powertrain coordination.

FAQ
What safety certifications does the TC299TX128F300NBCKXUMA1 hold?
The TC299TX128F300NBCKXUMA1 is certified to ISO 26262 ASIL-D at the device level, with supporting documentation including FMEDA reports, safety manuals, and hardware abstraction layer (HAL) libraries. It meets AEC-Q100 Grade 1 reliability requirements (–40 °C to +125 °C) and includes integrated safety mechanisms such as lockstep core checking, ECC on all memories, and hardware safety manager (HSM) monitoring.
Does this MCU support Ethernet Time-Sensitive Networking (TSN)?
No - the TC299TX128F300NBCKXUMA1 integrates standard 10/100 Mbps Ethernet MACs compliant with IEEE 802.3, but does not include TSN-specific features such as time-aware shapers, frame preemption, or scheduled traffic. Its Ethernet implementation supports AVB streaming and basic TCP/IP stacks, while deterministic timing is achieved via E-Ray and hardware timer synchronization.
Can the DFLASH be used for secure boot key storage?
Yes - the 768 KB DFLASH supports secure write-protection regions, hardware-based access control via the Memory Protection Unit (MPU), and ECC-protected storage. When combined with the Hardware Security Module (HSM) and boot ROM's verified boot flow, it enables tamper-resistant storage of cryptographic keys and firmware signature verification metadata.
What debug interface does the TC299TX128F300NBCKXUMA1 use?
The device uses a standardized JTAG/DAP interface compliant with ARM CoreSight, supporting multi-core debugging via Infineon's iLLD and DAVE™ toolchains. It includes SWD and JTAG transport modes, with dedicated debug access port (DAP) enabling non-intrusive trace capture, real-time variable inspection, and lockstep core visibility during development and validation.
