Architecture and performance
The Infineon TriCore v1.6P blends MCU control capabilities with DSP-like efficiency, enabling deterministic real-time behavior across powertrain, body, and industrial control tasks. At up to 200 MHz, the SAK-TC233L-32F200FAB offers ample headroom for time-critical loops, signal conditioning, and peripheral servicing. The 2 MB of embedded flash supports complex application stacks and diagnostic routines commonly required in automotive ECUs.
- Deterministic control: TriCore delivers low-latency interrupt service and predictable execution needed for closed-loop control.
- Code space for safety: 2 MB flash allows partitioning for bootloaders, diagnostics, and safety mechanisms alongside application code.
- System scalability within AURIX: The TC23xL family approach allows engineers to scale performance and features across related devices while keeping a consistent software model (verify pin and peripheral compatibility per derivative).
Because AURIX families use derivative-specific configurations, refer to Infineon’s technical reference manual(s) for precise cache, memory map, and accelerator details applicable to this MPN.
Safety and automotive readiness
- AEC‑Q100 Grade 1: Qualified for -40°C to +125°C ambient operation.
- ISO 26262 capable: The AURIX platform supports functional-safety implementations. Final ASIL levels depend on system-level architecture, diagnostics, and software measures.
- Robust operating range: Wide temperature support suits under-hood and cabin electronics, as well as harsh industrial environments.
These attributes make the SAK-TC233L-32F200FAB a solid choice for designs where reliability and safety are paramount. The use of TriCore, together with safety-oriented development flows, can help shorten the path to compliance when paired with appropriate system-level diagnostics.
Connectivity and I/O
Integrated interfaces cover key automotive and industrial buses and local communication needs:
- Automotive and field buses: CAN and LIN
- Serial communications: UART, SPI/QSPI, and I2C
- Mixed-signal: ADC for sensor interfacing
- Timers: General timing and control for PWM and scheduling
Exact counts, bit rates, and feature variations (e.g., number of channels, supported modes) are derivative-dependent. Designers should confirm availability and performance characteristics for the SAK-TC233L-32F200FAB in the official documentation.
Package, pinout, and mechanical
- Package: LQFP-100 (Low-Profile Quad Flat Package, 100 pins)
- Mounting: Surface Mount
- Board impact: The 100-pin footprint fits mid-range complexity designs, balancing I/O coverage and PCB area.
Pin multiplexing, power pin placement, and thermal guidance are reference-design-dependent. For land pattern, soldering profiles, and pin assignment diagrams, consult the datasheet and package application notes.
Operating conditions and power

Sourcing tips for automotive MCUs:
- Confirm program-based supply: Automotive MCUs often ship under program agreements. Lead times and minimum order quantities may differ from catalog components.
- Check date codes and storage conditions: For safety-related and high-reliability builds, ensure traceability through authorized distributors or direct manufacturer channels.
- Validate temperature grade and qualification: Ensure the exact AEC-Q100 grade and temperature range match your system’s environmental profile.
- Align with your safety concept: If you’re targeting specific ASIL levels, confirm safety-related features and diagnostics at the derivative level and plan your safety case accordingly.
If your build plan depends on firm availability, contact Infineon or authorized distributors early with forecasted volumes. The provided inventory snapshot here indicates no on-hand stock; availability varies by region and program status.
Compliance and environmental
- AEC‑Q100: Grade 1 qualification (-40°C to +125°C)

- RoHS: RoHS Compliant
For documentation traceability (e.g., PPAP or similar), coordinate with Infineon or your authorized supplier to obtain the required compliance packages.
Design-in considerations and migration
- Verify derivative specifics: Peripheral counts, RAM size, ADC resolution, and timing resources vary by device. Always bind your design to the SAK-TC233L-32F200FAB datasheet and reference manual.
- Clocking and power: Establish power budgets and clock trees from official electrical characteristics; low-power modes and wake-up sources are device dependent.
- PCB layout: Follow the package land pattern recommendations and ensure robust grounding/decoupling for mixed-signal accuracy (ADC) and EMC.
- Safety architecture: Map system safety goals (ASIL) to MCU features and external measures, including independent monitoring where required by your safety concept.
- Software portability: Within AURIX families, reuse is facilitated at the API and middleware layers, but confirm pin mux and peripheral availability when migrating across TC23xL derivatives.
