Product details
Overview
TC265D40F200NBCKXUMA1 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 lockstep safety architecture. It targets automotive ASIL-D safety-critical applications including engine control units and battery management systems.
For engineers reviewing the TC265D40F200NBCKXUMA1 datasheet, TC265D40F200NBCKXUMA1 pinout, TC265D40F200NBCKXUMA1 application, or TC265D40F200NBCKXUMA1 equivalent, key selection criteria include dual-core lockstep operation, 200 MHz real-time performance, integrated SMU, ECC-protected memory hierarchy, and support for AUTOSAR-compliant safety mechanisms.
Technical Context
The TC265D40F200NBCKXUMA1 implements a heterogeneous dual-core architecture: the primary TC1.6P core delivers deterministic real-time execution with 2 MAC/cycle capability and 16 KB ICACHE/8 KB DCACHE, while the secondary TC1.6E core provides binary-compatible background processing with 8 KB ICACHE and 0.125 KB DRB. Both cores operate up to 200 MHz across full industrial temperature range (–40 °C to +125 °C).
On-chip safety infrastructure includes a dedicated Safety Management Unit (SMU), ECC protection on all embedded SRAM and Flash, lockstepped shadow execution for the TC1.6P core, and a 48-channel DMA controller with safe data transfer monitoring. The device supports ASCLIN, QSPI, ETH (MII/RMII), E-Ray, and DSADC peripherals with hardware safety checking.
