SAK-TC299TX-128F300N Présentation
An automotive microcontroller (MCU) is a specialized microcontroller engineered to meet ISO 26262 functional safety requirements, providing lockstep CPU cores, ECC memory, and built-in self-test to detect random hardware faults. Within the broader semiconductor hierarchy, it sits under the MCU category, then the 32-bit microcontroller family, then the automotive-grade embedded computing tier, then the broader semiconductor taxonomy. The AURIX family specifically targets safety-critical drivetrain, chassis, and ADAS platforms where deterministic real-time response is mandatory.
Key features include up to 300 MHz triple-core TriCore execution, 8 MB Flash with ECC, 2776 KB on-chip SRAM, GTM for advanced timer/PWM generation, 6 CAN nodes, FlexRay interface, 94 analog input lines across multiple ADC modules, and a 3.3V/5V tolerant supply. The triple-core lockstep architecture permits ASIL-D capable system designs with full safety coverage.
The TC29xTX silicon pairs three TriCore v1.6.2 CPUs with a dedicated FPU and DSP extensions per core, plus a Generic Timer Module that delivers high-resolution PWM, capture/compare, and signal routing. Memory is partitioned so safety-critical code can be isolated from non-safety code in separate Flash and SRAM regions. Hardware security modules include a Hardware Security Module (HSM) for secure boot and cryptographic key storage.
Typical applications include engine management ECUs, transmission control units, electric power steering, integrated safety domain controllers, and chassis control modules. The wide integration of timers, ADC, and communication peripherals reduces external component count on drivetrain PCBs. AEC-Q100 qualification supports deployment in production vehicles across passenger car and commercial vehicle platforms.
When designing with the SAK-TC299TX, allocate sufficient PCB layers for decoupling of the multi-rail core supply. Use Infineon's AURIX iLLD drivers and the free AURIX Development Studio IDE to simplify peripheral configuration. Plan for boot mode strap configuration and HSM provisioning during manufacturing programming.

Applications typiques
SAK-TC299TX-128F300N convient pour 6 applications: Engine Management ECU, Electric Power Steering (EPS), Transmission Control Unit (TCU), ADAS Domain Controller, Chassis Control Module, Integrated Safety Domain Controller.
Engine Management ECU
The SAK-TC299TX-128F300N fits engine management ECUs because its triple-core TriCore 300 MHz configuration supports ASIL-D capable combustion control loops with deterministic real-time response. The 8 MB Flash holds multi-fuel calibration tables while 2776 KB SRAM absorbs transient signal processing during knock detection cycles. The integrated GTM module generates the high-precision injector and ignition timing pulses that modern direct-injection engines require, and 6 CAN nodes plus FlexRay connect to transmission, ABS, and hybrid domain controllers. Pin assignment on the LFBGA-516 package provides 94 ADC lines for crank, cam, knock, and lambda sensor acquisition with synchronous sampling windows down to microsecond resolution, removing the need for external ADC clusters in most powertrain architectures.
Recommandé
Electric Power Steering (EPS)
EPS controllers demand ASIL-D capable processors with deterministic torque-loop latency, which the SAK-TC299TX-128F300N provides through its lockstep TriCore cores and ECC memory. The GTM produces the precise PWM used for steering torque feedback motor control, while the integrated CAN FD bus connects to vehicle CAN-FD drivetrain networks at 2 Mbaud. Hardware Security Module support provides secure boot for the EPS controller, defending against unauthorized firmware replacement. The AEC-Q100 -40C to +125C ambient rating covers under-hood mounting positions on most passenger vehicles, and 94 ADC input lines deliver the multiple redundant torque and angle sensors demanded by ISO 26262 control loops.
Recommandé
Transmission Control Unit (TCU)
The SAK-TC299TX-128F300N suits TCU designs that require complex shift scheduling, torque management, and dual-clutch actuation. The three-core compute budget allows separate software partitions for shift arbitration, torque sensing, and clutch hydraulics without cross-core memory contention. 8 MB Flash provides capacity for multiple shift maps (sport, eco, trailer, snow), and 6 CAN/FlexRay channels link to engine, ABS, and body controllers. The 516-pin LFBGA package provides wide GPIO for hydraulic valve actuation signal routing plus ADC channels for clutch pressure and line pressure monitoring. Infineon's AURIX iLLD libraries and EB Tresos studio toolchain reduce time-to-market for production TCUs.
Recommandé
ADAS Domain Controller
The SAK-TC299TX-128F300N suits ADAS domain controllers that fuse sensor data from cameras, radar, and lidar, where the three-core configuration can run sensing, fusion, and vehicle-actuation control concurrently with the safety lockstep partner. The integrated Ethernet MAC supports high-throughput sensor data ingest, while GTM provides accurate timestamping of perception events. AURIX TC29x parts are marketed by Infineon for ADAS up to SAE Level 5 with appropriate software stack; the SAK-TC297TT variant is the dedicated ADAS sensor-fusion sub-set of this family. The 516-ball LFBGA allows high-density PCB routing for multiple sensor interfaces plus vehicle CAN-FD/CAN-XL downstream comms.
Recommandé
Chassis Control Module
The SAK-TC299TX-128F300N provides the multi-axis chassis control inside a single ECU, handling electronic stability, active suspension, and adaptive damping. Its ASIL-D capable triple-core lockstep plus ECC memory covers the integrity requirement for brake-by-wire interlocks, while the GTM module generates the precise PWM used for active suspension actuation. The 8 MB Flash absorbs complex ride-quality control tables for multiple driving modes, and CAN-FD plus FlexRay multiplex chassis commands to the central gateway. AEC-Q100 qualification plus -40C to +125C operation covers wheel-hub environment mounting for ride-height controller ECUs.
Recommandé
Integrated Safety Domain Controller
Safety domain controllers aggregate sensor inputs from around the vehicle to compute centralised chassis, drive, and occupant protection decisions. The SAK-TC299TX-128F300N supplies the deterministic ASIL-D capable compute for this aggregation, with three TriCore cores providing enough headroom for sensor polling, decision logic, and actuator command issuance in parallel. Ethernet permits high-bandwidth sensor clustering while 6 CAN channels plus FlexRay support traditional chassis networks during transition. The Hardware Security Module enables secure boot and cryptographic key storage that legal and cybersecurity standards increasingly mandate. The LFBGA-516 package supports the dense trace routing required by stacked sensor connector layouts.

Principaux différenciateurs
- Triple-core lockstep capable AURIX architecture (vs SAK-TC297TX-128F300N)
- Largest SRAM in the TC29x range at 2776 KB (vs SAK-TC298TX-128F300N)
- 6 CAN nodes plus FlexRay plus Ethernet (vs SAK-TC297TX-128F300N)
Notes de conception
The SAK-TC299TX-128F300N ships in PG-LFBGA-516-5 with very fine 0.8 mm pitch. Use at least a 6-layer PCB stack-up with dedicated GND and supply layers. Route matched-length differential pairs for Ethernet, FlexRay, and CAN-FD inside 3 m max and place 0402 decoupling within 1 ball-pitch of every VDD/VEXT pin.
AURIX TC29x multi-rail supplies require a low-impedance regulator sequence: 5V VEXT before 3.3V VDD and finally the 1.25V core. Use Infineon's TC39x/AURIX reference regulator (TLE7368 or TLF35584) and stagger enable pins to enforce the required power sequencing, otherwise the part may enter permanent reset.
Estimated: at 300 MHz across three cores with all peripherals active, the SAK-TC299TX-128F300N dissipates about 1.5 to 2.0 W under typical workload (input voltage 3.3 V, room temperature). The LFBGA-516 board-mounted junction-to-ambient is generally 12 to 18 C/W on a 4-layer PCB; ensure the PCB top layer is a continuous copper flood tied to GND balls to spread heat.
Do not skip configuration of the boot mode straps (PINSETCFG) before reset is released. Also lock the watchdog SCU_WDTCPUx registers from software. Both omissions lock up the device under debug and require cold reset to recover.
