Product details
Overview
TC264D40F200NBCLXUMA1 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 program flash, 96 KB data flash for EEPROM emulation, and lockstep safety architecture. It targets automotive powertrain and chassis control systems requiring ASIL-D compliance.
For engineers reviewing the TC264D40F200NBCLXUMA1 datasheet, TC264D40F200NBCLXUMA1 pinout, TC264D40F200NBCLXUMA1 application, or TC264D40F200NBCLXUMA1 equivalent, this device delivers deterministic real-time execution, integrated safety mechanisms (SMU, lockstep, ECC), and multi-channel communication interfaces including Ethernet, E-Ray, and ASC/DSADC - critical for functional safety validation in ISO 26262-compliant designs.
Technical Context
The TC264D40F200NBCLXUMA1 implements a dual-CPU safety architecture: the primary TC1.6P core executes time-critical tasks with 2 MAC/cycle DSP capability and 120 KB DSPR, while the TC1.6E shadow core runs in lockstep for fault detection. Both cores operate across full industrial temperature range (–40°C to +125°C) at up to 200 MHz.
Its on-chip memory subsystem includes 2.5 MB PFLASH with ECC, 96 KB DFLASH supporting EEPROM emulation, and scratchpad RAMs (DSPR/PSPR) with configurable retention. The SRI 64-bit crossbar enables concurrent access to peripherals including ETH, E-Ray, and 48-channel DMA - essential for high-integrity automotive domain controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC265D40F200NACXUMA1 | LQFP-176 package; adds 2x additional ASC channels and 1x extra DSADC module vs. TC264 | Required when higher peripheral count needed for complex chassis modules with >6 sensor inputs | Select if board layout accommodates larger footprint and additional serial/ADC resources are mandatory |
| TC267D40F200NACXUMA1 | BGA-292 package; integrates 2x Ethernet MACs and enhanced E-Ray bandwidth vs. TC264's single ETH | Targeted at zonal gateways requiring dual Ethernet ports and higher inter-domain throughput | Choose only when BGA assembly capability exists and dual-MAC Ethernet is architecturally required |
Compared with TC264D40F200NBCLXUMA1, the TC265 offers more I/O and peripherals in LQFP form, while the TC267 provides higher integration density and dual Ethernet - but both require different PCB layouts and lack drop-in compatibility due to pinout and package mismatch.
