FAQ

What is the maximum operating frequency of the ARM Cortex-M0 core in this device?

The XMC1402Q048X0128AAXUMA1 operates its ARM Cortex-M0 core at a maximum frequency of 48 MHz, delivering 0.84 DMIPS/MHz (40.3 DMIPS total) as measured by Dhrystone 2.1 benchmark. This frequency is fully supported across the –40°C to +105°C ambient temperature range with 1.8–5.5 V supply.

Does this microcontroller support hardware-accelerated field-oriented control (FOC)?

Yes - the integrated MATH coprocessor provides hardware CORDIC for 24-bit sine/cosine/tangent and 32-bit integer division, accelerating FOC inner-loop calculations. Combined with dual CCU8 timers for precise PWM generation and VADC with synchronized sampling, it enables sub-microsecond current loop execution without software overhead.

What debug interfaces are available, and do they require dedicated pins?

The device supports Serial Wire Debug (SWD) using only SWDIO and SWCLK pins - no dedicated reset or trace pins required. It also includes a single-pin bootloader interface via UART0 RX, allowing firmware updates without debugger connection. Both interfaces operate across the full voltage and temperature range.

Can the VADC measure signals beyond the supply rail, such as 0–5.5 V inputs with a 3.3 V VDDA?

Yes - the VADC supports an absolute input range of 0 V to 5.5 V regardless of VDDA setting, enabled by internal scaling circuitry. When VDDA = 3.3 V, the ADC uses an internal reference divider to maintain full-scale accuracy across the extended range, validated per datasheet Section 3.2.2.
