Infineon Technologies TC277T64F200NDCKXUMA2

Overview

TC277T64F200NDCKXUMA2 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three lockstep-capable CPU cores (two TC1.6P @ 200 MHz + one TC1.6E @ 200 MHz), 4 MB ECC-protected program flash, 384 KB data flash for EEPROM emulation, and integrated hardware safety mechanisms including SMU, MTU, and optional HSM. It targets ASIL-D automotive powertrain and chassis control systems requiring functional safety certification.

For engineers reviewing the TC277T64F200NDCKXUMA2 datasheet, TC277T64F200NDCKXUMA2 pinout, TC277T64F200NDCKXUMA2 application, or TC277T64F200NDCKXUMA2 equivalent, key selection criteria include dual-core lockstep configuration, 200 MHz real-time execution, on-chip safety monitoring (SMU/IOM/MTU), and automotive-grade BGA292 packaging with 5 V/3.3 V switchable I/O support.

Technical Context

The TC277 implements a heterogeneous multi-core architecture: two high-performance TC1.6P cores handle deterministic real-time tasks with 200 MHz operation, 120 KB DSPR, and dual MAC/FPU; the third TC1.6E core provides power-efficient background processing at identical clock speed but reduced cache and buffer resources. All cores share a 64-bit SRI crossbar and are supported by ECC-protected memory subsystems.

Safety-critical operation is enabled by hardware-level redundancy: lockstep shadow cores for both TC1.6P and TC1.6E configurations, Safety Management Unit (SMU) for alarm aggregation, Memory Test Unit (MTU) with MBIST and ECC initialization, and Hardware I/O Monitor (IOM) for digital pin integrity verification - all compliant with ISO 26262 ASIL-D requirements.

Key Specifications

Pinout & Package

TC277T64F200NDCKXUMA2 uses a 292-ball BGA package (15 × 15 mm, 0.8 mm pitch) with thermal pad. Pin functions are defined in Section 2.2 of the DC-Step datasheet (V1.2, 2019-04), supporting multiple I/O voltage domains, safety-redundant signal routing, and dedicated high-speed interface balls (ERAY, ETH, QSPI).

FAQ

What is the maximum operating frequency of each CPU core in the TC277T64F200NDCKXUMA2?

The TC277T64F200NDCKXUMA2 features two TC1.6P cores and one TC1.6E core, all rated for 200 MHz operation across the full industrial temperature range (−40 °C to +125 °C). This frequency is guaranteed under specified VDDP_1P3 (1.3 V ±3%) and VDDP_3V3 (3.3 V ±5%) supply conditions, with appropriate thermal management per the datasheet's thermal resistance limits.

Does this microcontroller include built-in hardware security features beyond basic flash protection?

Yes - the TC277T64F200NDCKXUMA2 includes an optional Hardware Security Module (HSM) supporting AES-128/256, SHA-256, RSA-2048, and TRNG. When enabled, the HSM isolates cryptographic operations from the main TriCore cores, provides secure boot verification, and manages key lifecycles in tamper-resistant memory, meeting EVITA Full and UNECE R155 compliance requirements.

How does the Safety Management Unit (SMU) interact with other safety peripherals like MTU and IOM?

The SMU acts as the central safety arbiter: it receives fault signals from MTU (memory test failures), IOM (I/O pin integrity violations), peripheral watchdogs, and lockstep mismatch detectors. Based on configurable alarm priorities and masking, the SMU triggers defined safe states - such as core reset, bus isolation, or safe output assertion - within programmable time windows aligned to ASIL-D timing constraints.

Can the TC277T64F200NDCKXUMA2 support both CAN FD and FlexRay simultaneously in the same application?

Yes - the device integrates six ASCLIN channels (supporting CAN FD up to 5 Mbit/s) and two dedicated ERAY controllers. These operate independently with separate clock domains and DMA channels, enabling concurrent high-speed CAN FD communication (e.g., body domain) and time-triggered FlexRay (e.g., powertrain domain) without resource contention or timing interference.
