Infineon Technologies TC336LP32F200SAALXUMA1

Overview

TC336LP32F200SAALXUMA1 from Infineon is a 32-bit automotive microcontroller unit (MCU) based on the AURIX™ TC3xx family, featuring a tri-core lockstep architecture with three independent TriCore™ CPUs clocked at 200 MHz, 4 MB of embedded flash, and ASIL-D functional safety compliance for powertrain and chassis control applications.

For engineers reviewing the TC336LP32F200SAALXUMA1 datasheet, TC336LP32F200SAALXUMA1 pinout, TC336LP32F200SAALXUMA1 application, or TC336LP32F200SAALXUMA1 equivalent, key selection criteria include ASIL-D certification, dual-lockstep core redundancy, integrated HSM for secure boot, 48-channel GPT12 timer, and Ethernet AVB interface support.

Technical Context

The device implements a safety-critical tri-core lockstep configuration where two cores execute identical code in parallel with cycle-accurate comparison, while the third core handles background tasks and diagnostics. It integrates a Hardware Security Module (HSM) compliant with EVITA Full and ISO/SAE 21434 for secure key management and cryptographic acceleration.

Memory subsystem includes 4 MB of ECC-protected flash with read-while-write capability, 2.5 MB of SRAM with parity/ECC, and configurable cache partitioning across cores. Peripheral set supports CAN FD (up to 12 channels), Ethernet AVB (100BASE-T1), and SENT interfaces for sensor communication.

FAQ

What is the maximum operating junction temperature for TC336LP32F200SAALXUMA1?

The device is qualified for operation up to 150 °C junction temperature per AEC-Q100 Grade 1 specifications. Thermal derating begins above 125 °C ambient, and the integrated temperature sensor provides real-time die temperature reporting via dedicated ADC channel with ±2 °C accuracy across the full range.

Does TC336LP32F200SAALXUMA1 support AUTOSAR Classic and Adaptive platforms?

Yes-it fully supports AUTOSAR Classic R4.x with certified MCAL drivers for all on-chip peripherals, and also enables AUTOSAR Adaptive via its virtualization-ready MMU and HSM-secured boot flow. The TriCore™ architecture allows simultaneous execution of Classic and Adaptive runtimes using hardware-isolated memory partitions and time-triggered scheduling.

How is functional safety achieved in the lockstep configuration?

Functional safety relies on hardware-level comparison of instruction execution between two lockstep cores: any mismatch triggers immediate error signal assertion, core isolation, and safe state entry within 3 clock cycles. The third core independently monitors lockstep health and executes safety-related diagnostics such as memory BIST and peripheral loopback tests.

Can the Ethernet AVB interface operate without external PHY components?

No-the Ethernet AVB interface requires an external 100BASE-T1 PHY (e.g., TJA1103 or LAN8770) for physical layer signaling. The MCU provides MAC-layer functionality only, including IEEE 802.1AS timestamping, gPTP synchronization, and AVB stream reservation, with direct RMII-like interface to the PHY via dedicated ETH pins.
