Product details
Overview
TC297TX128F300NBCKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P CPU cores, 8 MB program flash (PFLASH), 768 KB data flash (DFLASH) for EEPROM emulation, and ECC-protected SRAM/flash memory. It integrates a 128-channel safety DMA, lockstep shadow core for ASIL-D compliance, and supports automotive powertrain and chassis control applications.
For engineers reviewing the TC297TX128F300NBCKXUMA1 datasheet, TC297TX128F300NBCKXUMA1 pinout, TC297TX128F300NBCKXUMA1 application, or TC297TX128F300NBCKXUMA1 equivalent, key selection criteria include dual-core lockstep operation, 300 MHz real-time performance, integrated Ethernet (ETH), E-Ray, and ASCLIN interfaces, and functional safety certification per ISO 26262 up to ASIL-D.
Technical Context
The TC297TX128F300NBCKXUMA1 implements a dual-core TriCore™ architecture with one master and one lockstepped shadow core, enabling fault-detection via instruction-level comparison. Its SRI crossbar interconnect provides 64-bit parallel bus access between CPUs, DMA, and memory subsystems, minimizing latency in time-critical control loops.
It integrates safety-critical peripherals including E-Ray (flexible deterministic automotive network controller), ETH (10/100 Mbit/s MII/RMII), and DSADC (dual-slope ADC with 16-bit resolution and <1 LSB INL). All on-chip memories feature SEC-DED ECC, and reset logic complies with ISO 26262 ASIL-D requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC297TX128F300NACKXUMA1 | Same die, BGA292 package but with standard (non-automotive) temperature grade (−40°C to +125°C vs. −40°C to +150°C). | Not qualified for under-hood powertrain use; limited to cabin or chassis modules with lower ambient thermal stress. | Select only if operating junction temperature remains ≤125°C and ASIL-D certification is not required. |
| S32K344W1MTAT0S | NXP S32K344: single Arm Cortex-M7 core (240 MHz), 4 MB flash, no E-Ray, Ethernet only via external PHY. | Lacks native E-Ray and dual-lockstep TriCore; requires external safety monitor for ASIL-D - increases system complexity. | Prefer when Arm ecosystem tooling is mandated and E-Ray networking is not needed. |
Compared with TC297TX128F300NBCKXUMA1, the TC297TX128F300NACKXUMA1 sacrifices extended temperature capability and safety qualification, while the S32K344 requires external components to achieve equivalent ASIL-D functionality - increasing design risk and board area.

FAQ
What is the maximum junction temperature rating for TC297TX128F300NBCKXUMA1?
The device is rated for operation up to +150°C junction temperature, validated per AEC-Q100 Grade 0 qualification. This enables direct mounting in high-thermal-stress locations such as inverter control boards near IGBT modules, without derating under continuous 300 MHz operation.
Does TC297TX128F300NBCKXUMA1 support hardware-based secure boot?
Yes - it includes a dedicated BootROM (BROM) with immutable cryptographic verification using SHA-256 and RSA-2048 signatures. Secure boot validates PFLASH image authenticity before execution and enforces debug port lockdown when secure mode is active.
Can the DSADC measure current in shunt-based motor control applications?
Yes - each DSADC channel supports programmable gain (1× to 128×), bipolar input range (±200 mV), and hardware-triggered synchronous sampling with VADC. This enables precise shunt-based phase current measurement with <1 µs inter-channel skew and <0.5 LSB INL at 16-bit resolution.
Is external clock source required for E-Ray operation?
No - E-Ray uses the internal PLL-derived clock (up to 80 MHz) and does not require an external oscillator. However, the main system clock (from OSC_IN/OSC_OUT) must be present to initialize the PLL and configure E-Ray timing registers during startup.
