3. Run (operating) IDD measured using external square wave clock source (fXCLK = 6 MHz). All inputs 0.2 V from rail. No dc loads.
Less than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly affects run
IDD. Measured with all modules enabled.
4. Wait IDD measured using external square wave clock source (fXCLK = 6 MHz); all inputs 0.2 V from rail; no dc loads; less than
100 pF on all outputs. CL = 20 pF on OSC2; 15 k± 5% termination resistors on D+ and D– pins; all ports configured as inputs;
OSC2 capacitance linearly affects wait IDD
5. STOP IDD measured with USB in suspend mode; OSC1 grounded; REGOUT, D+, and D– not connected; no port pins sourcing
current.
