Product details

Overview

TC233L32F200FABKXUMA1 from Infineon is a 32-bit AURIX™ TriCore™ microcontroller with dual-lockstep safety architecture, 200 MHz CPU frequency, 2 MB eFlash with ECC, 192 KB SRAM with ECC, and TQFP-100 package. It integrates 6x CAN (including CAN FD), 2x LIN, 4x QSPI, 24-channel 12-bit ADC, GTM timer, SENT interfaces, and programmable HSM for ASIL-D automotive safety systems.

For engineers reviewing the TC233L32F200FABKXUMA1 datasheet, TC233L32F200FABKXUMA1 pinout, TC233L32F200FABKXUMA1 application, or TC233L32F200FABKXUMA1 equivalent, key selection criteria include lockstep core configuration, CAN FD channel count, flash ECC coverage, GTM timing resolution, and TQFP-100 thermal performance in -40°C to +125°C environments.

Technical Context

The TC233L32F200FABKXUMA1 implements a dual-core TriCore™ architecture with one main core and one lockstep core operating at 200 MHz, featuring clock delay diversity for fault detection. It includes redundant timer subsystems (GTM, CCU6, GPT12), safe DMA, and access permission control to meet ISO 26262 ASIL-D requirements.

Its peripheral set supports high-integrity automotive networking: 6x CAN controllers with data-rate-enhanced CAN FD, 2x FlexRay, 4x QSPI for flash expansion, and 24x 12-bit SAR ADC channels with hardware oversampling. The integrated HSM complies with EVITA Medium specifications and supports AES-128, SHA-256, and RSA-2048 cryptographic operations.

FAQ

What is the maximum junction temperature rating for TC233L32F200FABKXUMA1?

The device is qualified for operation up to +150°C junction temperature. Standard qualification covers -40°C to +125°C ambient; hot-package variants rated for Ta = +150°C are available on request and require specific ordering codes. Thermal derating curves and PCB layout guidelines for thermal pad soldering are provided in the TC23xL Hardware Design Guide Rev. 1.3.

Does TC233L32F200FABKXUMA1 support AUTOSAR OS and MCAL out of the box?

Yes-it is fully supported by Infineon's AURIX Development Studio v7.2+ and AUTOSAR 4.3-compliant MCAL libraries (v3.0.1+), including drivers for CAN FD, ADC, GTM, and HSM. Pre-certified ASIL-B safety packages and ISO 26262 work products for ASIL-D integration are available under NDA via Infineon's SafeTcore program.

How many CAN FD channels can operate simultaneously at 5 Mbit/s?

All six CAN FD controllers support simultaneous 5 Mbit/s data phase operation when configured with appropriate bus termination and transceivers (e.g., TLE9278). Each channel has independent bit timing registers and dedicated message RAM, enabling concurrent high-speed diagnostics, actuator control, and sensor streaming without arbitration delay.

Is external flash required to use the HSM for secure boot?

No-secure boot executes entirely from internal 2 MB eFlash with ECC. The HSM verifies digital signatures of boot images stored in protected flash sectors using public keys provisioned during manufacturing. External flash may be used for application code storage but is not involved in the root-of-trust chain or HSM cryptographic operations.
