FAQ
What is the maximum operating frequency of the XMC4104Q48F128BAXUMA1?
The XMC4104Q48F128BAXUMA1 operates at up to 120 MHz using its internal PLL, which accepts input clocks from 1–20 MHz crystals or external oscillators. This frequency is fully supported across the full -40°C to +85°C temperature range with appropriate VDDP supply regulation and PCB layout practices.
Does this MCU support functional safety standards like IEC 61508?
Yes - the XMC4104Q48F128BAXUMA1 includes hardware safety features such as lockstep-capable CPU (via optional dual-core configuration in higher derivatives), memory protection unit (MPU), window watchdog timer (WDT), and ECC on Flash and SRAM - enabling SIL2-compliant designs per IEC 61508 when used with Infineon's safety documentation and certified software libraries.
Can the USB interface operate without an external PHY?
Yes - the XMC4104Q48F128BAXUMA1 integrates a full-speed USB 2.0 device PHY, requiring only passive termination (1.5 kΩ pull-up on D+ and series resistors) and no external transceiver. This simplifies board design and reduces bill-of-materials for firmware update, debugging, and host-side diagnostics interfaces.
How many independent PWM channels does it support for motor control?
The device supports four independent High-Resolution PWM (HRPWM) channels with sub-nanosecond timing resolution, plus two CCU4 units (each with 4 capture/compare channels) and one CCU8 unit (with 8 channels). This enables full six-step commutation for BLDC motors or three-phase sinusoidal drive with dead-time control and fault shutdown response under 100 ns.
