Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC277TP64F200WDBKXUMA1 | Same core, 4 MB flash, 384 KB SRAM, adds second Ethernet MAC and additional CAN FD channel | Better suited for high-bandwidth gateways requiring dual Ethernet ports and extended memory for AUTOSAR adaptive stack | Select when >2 MB flash or dual Ethernet is required; otherwise TC275 offers lower cost and footprint |
| S32K344WAT0VLHT | NXP S32K3 series ARM Cortex-M7 core, 4 MB flash, ASIL-D certified, but lacks integrated Ethernet MAC | Requires external PHY for Ethernet; optimized for safety-critical powertrain and battery management rather than multi-protocol gateways | Prefer for ARM ecosystem compatibility or where Ethernet is not needed; TC275 provides native Ethernet integration |
Compared with TC277TP64F200WDBKXUMA1, the TC275 offers lower memory and interface count at reduced cost and thermal footprint; versus S32K344, it delivers integrated Ethernet and TriCore-specific real-time determinism critical for gateway latency budgets.

FAQ
What is the maximum operating temperature range for TC275T64F200WDBKXUMA1?
The TC275T64F200WDBKXUMA1 is qualified for operation from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating applies to the full device functionality, including flash programming, Ethernet MAC operation, and CAN FD communication at 5 Mbit/s, with thermal derating applied above 105 °C per Infineon's datasheet section 7.2.
Does TC275T64F200WDBKXUMA1 support AUTOSAR 4.3 and later versions?
Yes, the TC275T64F200WDBKXUMA1 is fully compatible with AUTOSAR 4.3 and 4.4 through Infineon's validated MCAL drivers and configuration tools. Its dual-core lockstep, memory protection units, and hardware watchdogs meet AUTOSAR OS requirements for safety partitions, while its Ethernet MAC supports both Classic and Adaptive AUTOSAR communication stacks.
How is functional safety achieved on this microcontroller?
Functional safety is implemented via hardware-enforced mechanisms: dual-core lockstep with comparator, SMPU/CIMPU for memory access control, built-in self-test (BIST) for flash and RAM, and dedicated safety endpoints (SEPs) for runtime monitoring. These features are documented in the certified ISO 26262 ASIL-D safety manual (Infineon document ID: AURIX_TC275_Safety_Manual_v2.1).
Can TC275T64F200WDBKXUMA1 be programmed via JTAG or only via DAP?
The TC275T64F200WDBKXUMA1 supports both JTAG (IEEE 1149.1) and SWD (Serial Wire Debug) interfaces for programming and debugging. JTAG is used for boundary scan and multi-core debug; SWD is supported via the DAP (Debug Access Port) for single-wire, low-pin-count development. Both interfaces enable flash programming, breakpoint setting, and real-time register inspection.
