Product details
Overview
TC233LP32F200NACKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a single TC1.6E CPU core operating at up to 200 MHz, 2 MB program flash (PFLASH), 128 KB data flash (DFLASH) 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 domain controllers requiring ASIL-D compliance support.
For engineers reviewing the TC233LP32F200NACKXUMA1 datasheet, TC233LP32F200NACKXUMA1 pinout, TC233LP32F200NACKXUMA1 application, or TC233LP32F200NACKXUMA1 equivalent, key selection criteria include its lockstepped safety architecture, ECC-protected memories, hardware security module (HSM) option, and real-time peripheral set including SENT, QSPI, and ASCLIN with LIN v2.1 support.
Technical Context
The TC233LP32F200NACKXUMA1 implements a safety-critical TriCore™ TC1.6E scalar CPU with binary compatibility to TC1.6P, coupled with a lockstepped shadow core for fault detection. Its memory subsystem includes 2 MB PFLASH and 128 KB DFLASH-both ECC-protected-and supports boot ROM (BROM) and memory test unit (MTU) with MBIST.
Peripheral integration centers on deterministic real-time I/O: dual MultiCAN+ modules (6 total CAN nodes, 128 message objects), one FlexRay E-Ray module (2 channels), IEEE 802.3-compliant Ethernet MAC with MII/RMII, and GTM for autonomous signal processing. Clocking uses dual PLLs-system PLL and ERAY_PLL-with external crystal or oscillator input.

FAQ
Does TC233LP32F200NACKXUMA1 include an integrated Ethernet PHY?
No. The part integrates only the IEEE 802.3-compliant Media Access Control (MAC) layer. An external PHY chip (e.g., LAN8720A or KSZ8081RNB) is required for physical layer signaling, connected via MII or RMII interface with proper clock synchronization and impedance-controlled routing.
What is the maximum operating temperature range for this microcontroller?
The TC233LP32F200NACKXUMA1 is qualified for operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. Junction temperature must remain below 150°C under sustained 200 MHz operation, necessitating appropriate PCB thermal design and heatsinking for high-power use cases.
Is hardware debug support available, and which interface does it use?
Yes-on-chip debug support complies with OCDS Level 1 and is accessible via either standard 4-wire JTAG (IEEE 1149.1) or the newer 2-wire Device Access Port (DAP). Both interfaces support full CPU, DMA, and bus visibility; DAP offers reduced pin count and higher bandwidth for trace streaming during development.
Can the 128 KB DFLASH be used for secure key storage in cryptographic operations?
Yes-DFLASH supports write-protection regions and can be partitioned into secure sectors. When paired with the optional Hardware Security Module (HSM), keys may be stored in encrypted DFLASH pages with access controlled by HSM internal logic, satisfying EVITA Medium and UNECE R155 cybersecurity requirements.
