39.8.8 PTC Characteristics at 125°C
The values in the Power Consumption table below are measured values of power consumption under the
following conditions:
Operating Conditions
VDD = 3.3V
Clocks
OSC8M used as main clock source, running undivided at 8MHz
CPU is running on flash with 0 wait states, at 8MHz
PTC is running at 4MHz
PTC Configuration
Mutual-capacitance mode
One touch channel
System Configuration
Standby sleep mode enabled
RTC running on OSCULP32K: used to define the PTC scan rate, through the event system
Drift Calibration disabled: no interrupts, PTC scans are performed in standby mode
Drift Calibration enabled: RTC interrupts (wakeup) the CPU to perform PTC scans. PTC drift calibration is
performed every 1.5 sec.
SAM D21 Family
