Infineon Technologies TC275TP64F200NDCKXUMA1

Overview

TC275TP64F200NDCKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three CPU cores: two high-performance TC1.6P (up to 200 MHz) and one power-efficient TC1.6E (up to 200 MHz), 4 MB program flash, 384 KB data flash for EEPROM emulation, and integrated Safety Management Unit (SMU) for ASIL-D automotive safety compliance. It targets engine control units, battery management systems, and ADAS domain controllers.

For engineers reviewing the TC275TP64F200NDCKXUMA1 datasheet, TC275TP64F200NDCKXUMA1 pinout, TC275TP64F200NDCKXUMA1 application, or TC275TP64F200NDCKXUMA1 equivalent, key selection criteria include dual-lockstep core support, ECC-protected memory hierarchy, ERAY and Ethernet interface timing, and functional safety certification per ISO 26262.

Technical Context

The TC275TP64F200NDCKXUMA1 implements a deterministic real-time architecture with three independent TriCore CPUs sharing a 64-bit SRI crossbar interconnect, enabling concurrent access to PFLASH, DFLASH, and SRAM resources. Its SMU monitors clock, voltage, temperature, and memory integrity via dedicated watchdogs and error injection logic.

It integrates dual-phase-locked loops (PLL and ERAY_PLL), supporting independent clock domains for application cores (up to 200 MHz), peripheral bus (SPB), and high-speed communication interfaces including ERAY, Ethernet (MII/RMII), and QSPI. All on-chip memories feature full ECC protection with automatic correction and lockstep error reporting.

FAQ

What is the maximum operating frequency of the TC275TP64F200NDCKXUMA1 CPU cores?

The TC275TP64F200NDCKXUMA1 features two TC1.6P cores and one TC1.6E core, each rated for up to 200 MHz across the full industrial temperature range (−40 °C to +125 °C). This frequency is sustained under worst-case voltage and temperature conditions with proper power supply decoupling and thermal management per Infineon's layout guidelines.

Does TC275TP64F200NDCKXUMA1 include hardware support for AUTOSAR OS and MCAL drivers?

Yes - Infineon provides certified AUTOSAR 4.x-compliant MCAL drivers (including DIO, PORT, ICU, GPT, PWM, ADC, CAN, LIN, ETH, and ERAY) and supports AUTOSAR OS v4.3+ via its AURIX Development Studio (ADS) toolchain. These drivers are validated for ASIL-B/D configurations and integrate with leading RTOS and configuration tools.

How is functional safety (ISO 26262) implemented in this microcontroller?

Functional safety is implemented through hardware-enforced mechanisms: lockstep CPU pairs with comparator logic, SMU with configurable safety alarms, ECC on all memories, MTU for memory self-test, and IOM for I/O pin integrity checking. These elements collectively enable ASIL-D compliance when used per Infineon's Safety Manual and FMEDA reports.

Can TC275TP64F200NDCKXUMA1 operate with a single external crystal?

Yes - it uses a single external crystal (20–40 MHz) connected to OSC_IN/OSC_OUT to feed the internal PLL, which generates the 200 MHz system clock. The backup clock circuitry supports an optional 32.768 kHz watch crystal for RTC operation, but the main clock tree relies solely on the primary crystal and PLL.
