SAK-TC1796-256F150EXBE Visão geral
What is a TriCore microcontroller? A TriCore is a hybrid 32-bit RISC/MCU/DSP architecture that combines the instruction throughput of a RISC processor, the deterministic interrupt behaviour of a microcontroller, and the single-cycle MAC DSP capabilities of a digital signal processor on a single bus-coupled die. This unified core reduces system BOM by replacing a separate MCU plus DSP, and it has been the principal automotive powertrain core architecture for Infineon until the AURIX TC2x/TC3x generations superseded it.
The TC1796 integrates a TriCore CPU with DSP functionality, a peripheral control processor (PCP2), up to 2 MB on-chip program Flash, 192 KB on-chip SRAM, a flexible bus architecture with 4 CAN nodes and a 32-bit external bus interface. The 150 MHz core delivers ample headroom for real-time engine control loops, while the built-in A/D converter unit features 8/10/12-bit resolution channels for sensor acquisition in powertrain ECUs.
Typical applications include gasoline and diesel engine management ECUs, transmission control units (TCU), electric power steering (EPS), and body control modules (BCM). SAK-TC1796-256F150EXBE is widely recognized as a stock ECU controller used in Mercedes-Benz and BMW powertrain controllers, where deterministic interrupt response and high-temperature operation are mandatory. Designers migrating from AUDO MAX to AURIX TC3xx must re-evaluate the toolchain, peripheral map and software layers.
When designing with this device, ensure PCB layout provides sufficient thermal copper under the BGA and that signal integrity on the external bus is verified to 150 MHz operation. Use Infineon's DAVE/DAVE Drive toolchain and the TriCore compiler for code generation, and validate the locking mechanism for end-of-line flash programming.

Aplicações típicas
SAK-TC1796-256F150EXBE é adequado para 6 aplicaçãos: Gasoline Engine Management ECU, Diesel Common-Rail ECU, Automatic Transmission Control Unit (TCU), Electric Power Steering (EPS), Body Control Module (BCM), Industrial Servo & Robotics Drive.
Gasoline Engine Management ECU
The SAK-TC1796-256F150EXBE's 150 MHz TriCore CPU and 2 MB Flash comfortably host the crank-shaft angle scheduling, lambda closed-loop, knock detection and torque-demand firmware used in modern gasoline ECUs. Its 8/10/12-bit ADC captures MAF, MAP, O2 and crank-position sensors while the 4 CAN nodes fan out to transmission, ABS and body modules. Per Infineon's TC1796 application notes, the deterministic TriCore interrupt latency supports the 0.5 ms cam/crank period demanded by sequential fuel injection.
Recomendado
Diesel Common-Rail ECU
Diesel common-rail ECUs use the SAK-TC1796-256F150EXBE to schedule high-pressure injection events with sub-microsecond jitter while running pilot/post-quantity fueling strategies. The 2 MB Flash absorbs typical Bosch/Siemens ECU calibration tables, and the on-chip PCP2 peripheral processor off-loads PWM generation for the 6-7 injector channels. Automotive-grade -40C to +125C operation is mandatory under-engine-bay thermal load.
Recomendado
Automatic Transmission Control Unit (TCU)
TCUs use the SAK-TC1796-256F150EXBE to execute shift scheduling, torque-management, and gear-clutch slip control algorithms at 150 MHz. The 4 CAN nodes attach to the engine ECU, ABS and chassis modules, while the multi-channel ADC samples line-pressure and temperature sensors. Per the TC1796 datasheet, the tri-core architecture's DSP MAC units accelerate the velocity-ratio state estimators inside modern 8/10-speed automatic transmissions.
Recomendado
Electric Power Steering (EPS)
EPS controllers exploit the SAK-TC1796-256F150EXBE's DSP MAC units for sensor-fused torque-vectoring and the 32-bit external bus to address dual motor-driver ASICs. Functional safety requires deterministic interrupt response - the TriCore's lockstep and trap architecture is well-suited to ASIL-D capable firmware. The 2 MB Flash comfortably fits assist-curve calibration tables across the entire vehicle trim line.
Recomendado
Body Control Module (BCM)
Body control modules often use the SAK-TC1796-256F150EXBE to consolidate lighting, door-mirror, seat-memory and bus-network functions; the 4 CAN and LIN channels interface with a CAN/CAN-FD backbone, while the BGA-416's high I/O count addresses dozens of low-side drivers and PWM-controlled interior lamps. The 2 MB Flash stores OEM variant tables (regional lighting, market option codes) and OTA scratch-space.
Recomendado
Industrial Servo & Robotics Drive
Outside automotive, the SAK-TC1796-256F150EXBE drives high-end industrial servo controllers, exploiting its DSP MAC for field-oriented-control (FOC) loops for three-phase BLDC and PMSM motors. The 8/10/12-bit ADC captures current shunt and resolver signals with sub-microsecond latency, while the 4 CANopen nodes interface with EtherCAT gateways. Designers relocating AUDO MAX code from cars to industrial servos can reuse the same TriCore toolchain, cutting time-to-market.

Notas de projeto
The P-BGA-416-4 demands a 6-layer or 8-layer PCB stack-up with 0.4 mm pitch escape routing. Use laser-drilled micro-vias under the BGA balls and a continuous GND plane on layer 2 to control return paths. Estimated: signal integrity on the 32-bit external bus at 75 MHz needs 50-ohm controlled impedance with <5 % tolerance; verify with TDR on coupons before committing to volume.
Although the BGA package has internal thermal balls, the corner quadrant of balls should be stitched to a top-side copper pad bonded to inner GND layers. Estimated: at 1 W typical automotive ECU dissipation, junction rise stays below 25 C with proper thermal vias - the 27 C/W theta_JA assumes a JEDEC JESD51 test board, not production ECU layout. Always verify with a thermocouple on a populated ECU.
The SAK-TC1796-256F150EXBE is a last-time-buy part - lock your purchase order and LTB allocation before commencing PCB layout. Do not assume any later-Infineon TriCore will drop in; per Infineon migration notes, switching to AURIX TC3xx forces PCB rework, toolchain re-validation, and full software re-porting. Confirm EMC, ESD, and EOL flash programming compatibility for OEM programs.
When routing the 4 CAN signals, keep the bus twisted-pair under 100 ohm differential impedance and place the TLE7259-3GE transceiver within 50 mm of the BGA CAN balls. The TC1796's CAN clock domain is asynchronous - if you remap CAN0/1/2/3 across non-adjacent balls, place a ferrite bead on each CAN_H/L run to suppress common-mode switching transients.
Isolate the external bus data/address lines on inner signal layers and keep them 2 x trace-width away from any 5 V H-bridge driver trace. The BGA-416's high I/O density makes it tempting to fan out on top side only, but production designs benefit from inner-layer escape to maintain the EMC headroom needed for OEM CISPR-25 automotive compliance.
