Product details
Overview
TC277TP64F200NDCLXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three CPU cores (two TC1.6P super-scalar and one TC1.6E scalar), 4 MB program flash, 384 KB data flash for EEPROM emulation, 200 MHz max clock frequency, and integrated hardware safety mechanisms including lockstep shadow cores, ECC-protected memories, and Safety Management Unit (SMU). It targets automotive powertrain and chassis control systems requiring ASIL-D compliance.
For engineers reviewing the TC277TP64F200NDCLXUMA1 datasheet, TC277TP64F200NDCLXUMA1 pinout, TC277TP64F200NDCLXUMA1 application, or TC277TP64F200NDCLXUMA1 equivalent, key selection criteria include triple-core real-time determinism, on-chip HSM support, ERAY/ETH/ASCLIN interface count, BGA292 package thermal performance, and functional safety certification evidence per ISO 26262.
Technical Context
The TC277TP64F200NDCLXUMA1 implements a heterogeneous multi-core architecture: two high-performance TC1.6P cores (200 MHz, dual MAC/FPU, 120 KB DSPR) operate in parallel with a power-efficient TC1.6E core (200 MHz, 112 KB DSPR), all sharing a 64-bit SRI crossbar interconnect and ECC-protected memory subsystem. Core lockstep pairs enable ASIL-D fault detection.
It integrates safety-critical peripherals including ERAY (flexible data-rate automotive bus), Ethernet MAC (10/100 Mbit/s RMII/MII), four ASCLIN channels with LIN 2.1/J2602 support, and a 64-channel DMA controller with safe transfer arbitration. The SMU monitors voltage, temperature, clock, and memory integrity via dedicated watchdogs and error injection paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC275TP64F200NACXUMA1 | Same core architecture but 2 MB PFLASH, no HSM, LQFP176 package (lower I/O count, higher thermal resistance) | Suitable for cost-sensitive ASIL-B chassis modules where cryptographic security and flash density are non-critical | Select when BGA assembly is unavailable or board space permits larger footprint and thermal derating is acceptable |
| S32K344WAT0MLLQZ | NXP S32K3 series: Arm Cortex-M7 + M33 dual-core, 4 MB flash, ASIL-D certified, but lacks native ERAY and TriCore real-time determinism | Preferred for new designs targeting AUTOSAR Adaptive and Linux-based domain controllers needing Arm ecosystem tooling | Choose if Arm software compatibility, AUTOSAR Adaptive support, or integrated PCIe/USB outweighs TriCore's deterministic latency advantage |
Compared with TC277TP64F200NDCLXUMA1, the TC275 variant trades flash capacity and security for package flexibility and cost, while the S32K344 offers Arm toolchain alignment at the expense of native ERAY integration and TriCore's cycle-exact real-time predictability.

FAQ
What is the maximum operating temperature range for TC277TP64F200NDCLXUMA1?
The TC277TP64F200NDCLXUMA1 is qualified for operation from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. Its internal temperature sensor and SMU monitor die temperature in real time, triggering thermal shutdown if junction exceeds 150 °C. This rating applies to the full 200 MHz performance range without derating.
Does TC277TP64F200NDCLXUMA1 include hardware cryptographic acceleration?
Yes-when configured with the optional Hardware Security Module (HSM), it provides dedicated AES-128/256, SHA-256, and RSA-2048 acceleration, secure key storage in tamper-resistant memory, and hardware-enforced secure boot. The HSM operates independently of the main TriCore cores and is certified to Common Criteria EAL4+ for automotive use cases.
How does the ERAY interface differ from standard CAN in TC277TP64F200NDCLXUMA1?
The ERAY controller supports flexible data-rate communication up to 20 Mbit/s with deterministic, time-triggered scheduling-unlike event-triggered CAN. It includes built-in synchronization, slot-based arbitration, and error containment islands, enabling seamless integration into AUTOSAR-compliant time-triggered networks for steer-by-wire and brake-by-wire systems.
Is external RAM required for running AUTOSAR OS on TC277TP64F200NDCLXUMA1?
No-AUTOSAR OS can execute entirely from on-chip resources: the 120 KB DSPR per TC1.6P core and 112 KB DSPR on TC1.6E provide sufficient RAM for OS kernel, stacks, and ISRs. External RAM is optional only for large application buffers or non-safety partitions; all safety-critical AUTOSAR modules run in protected internal SRAM with ECC.
