Product details

Overview

TC299TP128F300NBCKXUMA2 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P CPU cores, lockstep shadow core for ASIL-D safety compliance, 8 MB program flash with ECC, 768 KB data flash for EEPROM emulation, and integrated 128-channel DMA. It targets automotive powertrain and chassis control systems requiring functional safety up to ISO 26262 ASIL-D.

For engineers reviewing the TC299TP128F300NBCKXUMA2 datasheet, TC299TP128F300NBCKXUMA2 pinout, TC299TP128F300NBCKXUMA2 application, or TC299TP128F300NBCKXUMA2 equivalent, key selection criteria include dual-core lockstep timing integrity, ERAY/ETH/ASCLIN interface coexistence, BGA516 thermal-mechanical reliability, and flash ECC coverage across PFLASH/DFLASH/LMU memory domains.

Technical Context

The TC299TP128F300NBCKXUMA2 implements a deterministic real-time architecture with two independent TriCore™ TC1.6P superscalar CPUs (300 MHz max), each with dedicated 120 KB DSPR + 32 KB PSPR RAM, 16 KB ICACHE, and 8 KB DCACHE. The lockstepped shadow core provides hardware-level fault detection for safety-critical execution paths.

Its on-chip communication subsystem includes ERAY (flexible time-triggered bus), 10/100 Ethernet MAC with MII/RMII support, 6x ASCLIN (UART/SPI/LIN), QSPI, I²C, and EBU parallel interface - all accessible via a 64-bit SRI crossbar enabling concurrent master access without arbitration stalls.

Use Value: Achieves <500 ns inter-core synchronization jitter and DSADC-based current sampling at 200 kSPS for field-oriented control stability.

Brake-by-Wire System

Vehicle Domain Controller

Use Scenario: Redundant hydraulic pressure modulation and wheel-speed-based ABS/EBD actuation in electromechanical brake modules.

IC Role / Device Role / Timing Role: Safety island processor managing ASIL-D braking decisions, interfacing with dual-redundant CAN FD and ERAY networks.

Use Value: Delivers <1 ms end-to-end latency from wheel speed input to solenoid drive output using hardware-accelerated CRC and DMA-driven peripheral chaining.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TC297TP128F300NACXUMA1	Same dual-core TC1.6P @ 300 MHz, but BGA416 package (smaller footprint, reduced peripheral count: no ETH, only 1 ERAY channel).	Targeted at cost-sensitive chassis modules where Ethernet connectivity and dual ERAY are not required.	Select when board space is constrained and ASIL-D safety is needed without full TC299 peripheral set.
S32K344WAT0VLQY	NXP S32K3 series with Arm Cortex-M7 + Cortex-M33 lockstep; 320 MHz, 4 MB flash, supports AUTOSAR Adaptive but lacks ERAY and VADC/DSADC integration.	Focused on zonal ECU architectures with Linux/AUTOSAR Adaptive middleware; no native support for legacy time-triggered buses.	Prefer for next-gen software-defined vehicles requiring POSIX-compliant RTOS and Ethernet TSN, not legacy ERAY/CAN FD hybrid systems.

Compared with TC299TP128F300NBCKXUMA2, TC297 offers footprint reduction at the cost of Ethernet and second ERAY channel, while S32K344 trades mature time-triggered peripheral integration for adaptive compute flexibility - making TC299 optimal for safety-critical powertrain systems demanding deterministic ERAY/Ethernet coexistence.

FAQ

What is the maximum operating temperature range for TC299TP128F300NBCKXUMA2?

The TC299TP128F300NBCKXUMA2 is qualified per AEC-Q100 Grade 1, supporting continuous operation from −40°C to +125°C ambient temperature. Junction temperature must remain below +150°C under worst-case power dissipation, verified via thermal simulation using the provided Ψ_JB and Ψ_JT values in the package outline document.

Does TC299TP128F300NBCKXUMA2 support secure boot with cryptographic verification?

Yes - it features ROM-based secure boot with SHA-256 hash verification of the first boot image loaded from PFLASH or external memory. Public key storage is implemented in one-time-programmable (OTP) fuses, and signature validation occurs before any user code execution, preventing unauthorized firmware loading.

How many independent clock domains does TC299TP128F300NBCKXUMA2 support?

The device integrates four independent clock domains: CPU core (PLL-derived up to 300 MHz), peripheral bus (divided from core clock), ERAY/ETH (separate PLL with spread-spectrum capability), and low-power domain (RTC, WDT, backup registers). Each domain has configurable gating and frequency scaling via the Clock Generation Unit (CGU).

Can TC299TP128F300NBCKXUMA2 directly interface with 5 V sensors without level-shifting?

Yes - selected GPIO pins (including ASCLIN, QSPI, and EBU address/data lines) are 5 V-tolerant when configured as inputs. This allows direct connection to 5 V analog sensors or legacy digital peripherals without external level shifters, provided VDDP_3P3 remains at 3.3 V and input voltage does not exceed 5.5 V.
