Product details
Overview
TC264D40F200WBCKXUMA1 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 integrated Safety Management Unit (SMU) for ASIL-D compliance. It targets automotive safety-critical applications including electric powertrain control and brake-by-wire systems.
For engineers reviewing the TC264D40F200WBCKXUMA1 datasheet, TC264D40F200WBCKXUMA1 pinout, TC264D40F200WBCKXUMA1 application, or TC264D40F200WBCKXUMA1 equivalent, key selection criteria include dual-core lockstep capability, 48-channel safe DMA, ERAY and Ethernet interface support, and full temperature-range operation up to 125°C in LQFP144 package.
Technical Context
The device implements a heterogeneous dual-core architecture: the TC1.6P core delivers real-time deterministic performance with 2 MAC/cycle DSP capability and 120 KB DSPR, while the TC1.6E core provides binary-compatible low-power execution with 72 KB DSPR and DRB buffer. Both cores operate at up to 200 MHz across −40°C to +125°C ambient.
On-chip memory hierarchy includes ECC-protected 2.5 MB PFlash with read-while-write capability, 96 KB DFlash with wear-leveling support for EEPROM emulation, and dedicated scratchpad RAMs. The SRI crossbar enables concurrent 64-bit data transfers between CPUs, DMA, and peripherals without arbitration bottlenecks.

FAQ
What is the maximum operating frequency of each CPU core in TC264D40F200WBCKXUMA1?
The TC1.6P super-scalar core and TC1.6E scalar core both operate at up to 200 MHz across the full industrial temperature range (−40°C to +125°C), as verified in the Electrical Specifications section (3.4 Operating Conditions) of the official Infineon datasheet V1.0 (2017-06). This frequency is sustained under worst-case voltage and temperature conditions with no derating required.
Does TC264D40F200WBCKXUMA1 support hardware-based cryptographic acceleration?
No-TC264D40F200WBCKXUMA1 does not include a Hardware Security Module (HSM) or dedicated cryptographic accelerators. It relies on software-based crypto libraries executed on the TriCore CPUs. For hardware-accelerated AES/SHA/RSA, Infineon's later-generation TC275 or TC3xx devices must be selected, as confirmed in the Summary of Features and Peripheral Overview sections of the datasheet.
What is the purpose of the "WBCK" suffix in the part number TC264D40F200WBCKXUMA1?
The "WBCK" suffix denotes the specific package and qualification variant: W = wettable flank (for automated optical inspection), B = LQFP144 package, C = commercial temperature grade (−40°C to +125°C), K = lead-free and RoHS-compliant finish. This coding aligns with Infineon's standard part numbering scheme documented in the Package Outline chapter (3.36) of the datasheet.
Can TC264D40F200WBCKXUMA1 execute code directly from DFlash memory?
No-DFLASH (96 KB) is designated exclusively for data storage and EEPROM emulation; it cannot be executed from. Code execution is supported only from PFlash (2.5 MB), BootROM (BROM), or SRAM (DSPR/PSPR). This functional separation is explicitly stated in Section 1 Summary of Features and reinforced in the Memory Map chapter of the datasheet.
