Product details
Overview
TC267D40F200NBCLXUMA1 from Infineon Technologies is a 32-bit dual-core AURIX™ microcontroller featuring one TC1.6P super-scalar TriCore CPU (200 MHz) and one TC1.6E scalar TriCore CPU (200 MHz), 2.5 MB ECC-protected PFlash, 96 KB DFlash for EEPROM emulation, and BGA292 package. It integrates safety-critical functions including lockstep shadow core, Safety Management Unit (SMU), and ECC-protected 48-channel DMA - designed for automotive powertrain and chassis control systems requiring ASIL-D compliance.
For engineers reviewing the TC267D40F200NBCLXUMA1 datasheet, TC267D40F200NBCLXUMA1 pinout, TC267D40F200NBCLXUMA1 application, or TC267D40F200NBCLXUMA1 equivalent, key selection criteria include dual-core real-time determinism, on-chip flash ECC coverage, ERAY/ETH/ASCLIN interface count, BGA292 thermal performance, and SMU-configurable fault reaction behavior.
Technical Context
The TC267D40F200NBCLXUMA1 implements a lockstepped TC1.6P core with full instruction-level redundancy and hardware-assisted safety checking via SMU. Its SRI crossbar enables concurrent access to PFlash, DFlash, and DSPR/PSPR memories across both CPUs while maintaining temporal isolation for safety partitions.
It supports multiple clock domains: a 200 MHz PLL-driven core clock, independent 100 MHz ETH/ERAY clocks, and configurable 5 V / 3.3 V I/O pads with programmable pull-up/down reset behavior. The device includes dedicated safety peripherals - DSADC (2× 16-bit sigma-delta ADCs), HSCT (high-speed capture timers), and ERAY controller - all accessible under SMU supervision.

FAQ
What is the maximum operating frequency of each CPU core in the TC267D40F200NBCLXUMA1?
The TC267D40F200NBCLXUMA1 features two independent TriCore CPUs: the TC1.6P super-scalar core runs at up to 200 MHz across the full –40 °C to +125 °C temperature range, and the TC1.6E scalar core also operates at up to 200 MHz with binary compatibility. Both cores maintain full performance without derating under automotive thermal conditions.
Does TC267D40F200NBCLXUMA1 support Ethernet communication, and what PHY interface modes are available?
Yes, TC267D40F200NBCLXUMA1 integrates a full IEEE 802.3-compliant Ethernet MAC with MII and RMII interface support. It supports 10/100 Mbps operation, includes dedicated ETH_MDC/ETH_MDIO for PHY register access, and provides reference clock outputs for external PHY synchronization - enabling time-sensitive networking in automotive domain controllers.
How is functional safety implemented in TC267D40F200NBCLXUMA1 beyond lockstep execution?
Beyond lockstep CPU cores, TC267D40F200NBCLXUMA1 implements safety via the Safety Management Unit (SMU), which monitors voltage, temperature, clock stability, and memory errors. It enforces ECC on all memories, provides safe DMA with channel-level protection, and supports configurable fault reactions (reset, interrupt, or safe state assertion) - all certified to ISO 26262 ASIL-D requirements.
What flash memory types and capacities are integrated, and how is EEPROM emulation handled?
The device integrates 2.5 MB of ECC-protected Program Flash (PFlash) and 96 KB of Data Flash (DFLASH). DFLASH is specifically architected for EEPROM emulation: it supports byte-wise write/erase with wear leveling managed by the built-in Flash API (FEE), enabling reliable parameter storage with >100k erase cycles and data retention >20 years at 125 °C.
