Cortex-M0 at 48 MHz — what the core speed means for your loop
The 48 MHz clock is the practical ceiling for single-cycle multiply and tight loop execution on this core; budget your timing closure around it.
The 105°C ceiling is the junction limit at full load — derate the I/O drive current above 85°C if you are sinking more than 10 mA per pin.
Data converters: 13-channel 12-bit ADC, dual 12-bit DAC
The 13-channel 12-bit ADC and two 12-bit DAC channels let this MCU handle analog feedback loops — current sensing on a BLDC motor phase, or setting a reference voltage for an external comparator — without a separate analog front-end. The ADC samples at up to 1 Msps; pair it with the DMA to capture a burst of readings without CPU intervention.
