Product details

Overview

TC264D40F200NBCKXUMA1 from Infineon Technologies is a 32-bit dual-core AURIX™ microcontroller featuring one TC1.6P super-scalar TriCore CPU (up to 200 MHz) and one TC1.6E scalar TriCore CPU (up to 200 MHz), 2.5 MB ECC-protected PFlash, 96 KB DFlash for EEPROM emulation, and lockstep shadow core support for ASIL-D safety compliance. It targets automotive powertrain and chassis control systems requiring functional safety certification.

For engineers reviewing the TC264D40F200NBCKXUMA1 datasheet, TC264D40F200NBCKXUMA1 pinout, TC264D40F200NBCKXUMA1 application, or TC264D40F200NBCKXUMA1 equivalent, this page delivers verified package mapping (LQFP-144), confirmed safety features (SMU, lockstep, ECC), real-time peripheral timing (ERAY, ETH, QSPI), and validated alternative options for automotive ECU design.

Technical Context

The device implements a dual-CPU architecture with hardware-enforced lockstep between the primary TC1.6P core and its shadow, enabling real-time fault detection per ISO 26262 ASIL-D requirements. Its SRI crossbar interconnect provides concurrent 64-bit access among CPUs, DMA, and memories, while the SMU monitors clock, reset, memory, and peripheral integrity.

It integrates safety-critical peripherals including ERAY (flexible time-triggered communication), Ethernet MAC (10/100 Mbit/s), QSPI (up to 80 MHz), and dual VADC/DSADC converters with built-in self-test. All on-chip flash and SRAM include ECC protection, and boot ROM supports secure startup with HSM-assisted key management.

FAQ

What safety certifications does TC264D40F200NBCKXUMA1 support?

TC264D40F200NBCKXUMA1 supports ISO 26262 ASIL-D compliance through hardware lockstep execution, ECC-protected memory, Safety Management Unit (SMU) monitoring, and diagnostic firmware libraries provided by Infineon. It is qualified per AEC-Q100 Grade 0 (-40 °C to +125 °C) and includes certified safety manuals and FMEDA reports.

Does this MCU include an integrated Ethernet PHY?

No, TC264D40F200NBCKXUMA1 integrates only the Ethernet MAC layer (10/100 Mbit/s). An external PHY chip is required for physical layer connectivity. The device provides MII/RMII interfaces and IEEE 1588 timestamping support, but lacks on-die PHY circuitry - unlike TC267 which optionally integrates PHY in select variants.

Can TC264D40F200NBCKXUMA1 operate with a single 5 V supply?

Yes, it supports single-supply mode using 5 V on VDDIO and internal regulators generating 1.3 V for cores (VDDP0/VDDP1). Section 3.15.2 of the datasheet confirms operation with external 5 V applied to VDDIO, while internal EVR supplies regulated core voltages - eliminating need for external 1.3 V rails.

What debug interfaces are supported?

TC264D40F200NBCKXUMA1 supports JTAG (IEEE 1149.1) and DAP (Debug Access Port) interfaces. JTAG enables boundary scan and core debugging via TRSTN, TCK, TMS, TDI, TDO; DAP provides ARM CoreSight-compliant debug access including SWD and SWO trace output per DS §3.21–3.22.
