FAQ

What is the maximum operating frequency of the XMC1402Q040X0200AAXUMA1?

The XMC1402Q040X0200AAXUMA1 runs its ARM Cortex-M0+ core at up to 48 MHz, with all peripherals-including ADC, DAC, and CCU timers-fully operational at this frequency. Flash wait states are automatically managed via the embedded prefetch buffer, ensuring zero-wait-state execution from internal flash at rated speed.

Does this MCU support hardware-based motor control algorithms like FOC?

Yes. The XMC1402Q040X0200AAXUMA1 includes dedicated hardware accelerators for field-oriented control: CCU8 timers provide synchronized PWM generation with dead-time control and fault protection, while dual ADCs support simultaneous current sampling triggered by timer events-enabling real-time FOC loop execution within 1–2 µs latency.

Is the VQFN package thermally enhanced for continuous motor drive operation?

Yes. The 40-pin VQFN package features an exposed thermal pad (EP) that must be soldered to a PCB copper pour connected to ground. Thermal resistance θ_JA is 42 °C/W under standard JEDEC 2-layer board conditions, enabling sustained 48 MHz operation at ambient temperatures up to 85 °C with proper layout.

Can the integrated USB interface be used for both firmware updates and debug tracing?

Yes. The full-speed USB 2.0 device interface supports CDC ACM class for firmware updates via virtual COM port and also enables real-time debug tracing using Infineon's DAVE™ IDE with SWD-over-USB bridge functionality-no external debugger required for basic trace and variable inspection during development.
