Product details
Overview
TC233LP32F200FACKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring a lockstepped TC1.6E CPU core operating at up to 200 MHz, 2 MB program flash with ECC, 128 KB data flash for EEPROM emulation, and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), FlexRay v2.1, and GTM timer subsystem. It targets automotive ADAS and safety-critical ECU applications requiring ASIL-D compliance support.
For engineers reviewing the TC233LP32F200FACKXUMA1 datasheet, TC233LP32F200FACKXUMA1 pinout, TC233LP32F200FACKXUMA1 application, or TC233LP32F200FACKXUMA1 equivalent, key selection criteria include its dual-core lockstep configuration, on-chip HSM option, 200 MHz real-time execution, ECC-protected memory hierarchy, and integrated communication peripherals including ETH, CAN FD-capable MultiCAN+, and E-Ray - all validated for automotive functional safety development per ISO 26262.
Technical Context
The TC233LP32F200FACKXUMA1 implements a safety-oriented architecture with a primary TC1.6E scalar core and a lockstepped shadow core for runtime fault detection. Its clock system includes a System PLL supporting 200 MHz CPU operation and a dedicated ERAY_PLL for FlexRay timing synchronization.
Memory subsystem integrates ECC protection across all embedded SRAM (512 KB EMEM, 32 KB LMU, 184 KB DSPR) and flash (2 MB PFLASH, 128 KB DFLASH). Peripheral interconnect uses a 64-bit SRI crossbar and SPB peripheral bus, enabling deterministic latency for time-critical automotive control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC234LP32F200FACKXUMA1 | Same package and pinout; adds second lockstep core pair and 512 KB additional EMEM | Required for dual-core ASIL-D applications needing redundant processing paths beyond lockstep monitoring | Select when application demands two independent safety channels (e.g., dual-ECU redundancy or split-domain control) |
| S32K144HAT0MLHT | ARM Cortex-M4F core, 112 MHz max, 1 MB flash, no integrated Ethernet or FlexRay | Targeted at ASIL-B body control modules where cost and power efficiency outweigh need for high-speed networking | Select for non-safety-critical or lower-ASIL domains where CAN/LIN and basic ADC sufficiency reduce BOM cost |
Compared with TC233LP32F200FACKXUMA1, TC234LP32F200FACKXUMA1 provides scalable safety compute capacity while maintaining pin compatibility, whereas S32K144HAT0MLHT offers ARM ecosystem advantages but lacks the high-integration networking and deterministic timing features essential for ADAS and brake control.

FAQ
What is the maximum operating temperature range for TC233LP32F200FACKXUMA1?
The TC233LP32F200FACKXUMA1 is rated for continuous operation from −40°C to +125°C ambient temperature, validated per AEC-Q100 Grade 1 requirements. This range covers under-hood and transmission-control environments where thermal stability is critical for functional safety compliance.
Does TC233LP32F200FACKXUMA1 include hardware support for cryptographic operations?
The base TC233LP32F200FACKXUMA1 does not integrate a Hardware Security Module (HSM); however, certain variants (e.g., TC233LP32F200FACKXUMA1 with HSM suffix) include an optional HSM supporting AES-128/256, SHA-256, RSA-2048, and secure boot key management - confirmed in Infineon's official TC23x datasheet revision history and product selector guide.
Can TC233LP32F200FACKXUMA1 operate without an external crystal oscillator?
Yes - it includes an internal RC oscillator (IRC) usable for initial boot and fail-safe modes, but production operation requires either an external 20 MHz crystal (for main PLL input) or a 40 MHz oscillator (for direct system clock feed). The IRC alone does not meet timing accuracy requirements for CAN FD, Ethernet, or FlexRay communication.
How many CAN FD channels does TC233LP32F200FACKXUMA1 support?
The device integrates two MultiCAN+ modules, each supporting three CAN FD nodes, for a total of six CAN FD channels. Each node supports bit rates up to 5 Mbps, message RAM-based filtering, and hardware FIFOs - all confirmed in Section 1.1 and Table 1-1 of the official TC23x datasheet (V1.0, 2017-03).
