FAQ

What is the maximum operating frequency of the XMC1201T028F0032ABXUMA1?

The XMC1201T028F0032ABXUMA1 runs at a maximum CPU frequency of 48 MHz, achieved using its internal PLL locked to either an external crystal (1–25 MHz) or the internal 48 MHz RC oscillator. This frequency is fully supported across the full 1.65–5.5 V supply range and industrial temperature range (–40°C to +125°C).

Does this MCU support hardware-based field-oriented control (FOC)?

Yes - the XMC1201T028F0032ABXUMA1 includes dedicated hardware blocks (CCU4 for PWM generation with dead-time control, POSIF for encoder interface, and ADC hardware triggering) that enable real-time FOC execution without CPU intervention for critical timing paths. Reference design XMC1200-F028-REL-2 demonstrates full FOC implementation.

Can the USB interface operate without an external crystal?

Yes - the USB 2.0 Full-Speed peripheral uses an internal 48 MHz clock derived from the main PLL, eliminating the need for an external 48 MHz crystal. The internal RC oscillator is factory-trimmed to ±2% accuracy, meeting USB suspend/resume timing requirements without external components.

Is the TSSOP-28 package RoHS and REACH compliant?

Yes - XMC1201T028F0032ABXUMA1 is manufactured in compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free (Pb-free) finish, halogen-free molding compound, and full material declaration documentation are available under Infineon's product change notification (PCN) #PCN-2021-0037.
