NOTES:
1. VDD = 4.0 to 5.5 Vdc, VSS = 0 Vdc, TA = TL to TH, unless otherwise noted.
2. Typical values reflect average measurements at midpoint of voltage range, 25
°C only.
3. Run (operating) IDD measured using external square wave clock source. 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 (fCGMXCLK = 6 MHz); all inputs 0.2 V from rail; no dc loads; less than 100
pF on all outputs. CL = 20 pF on OSC2; USB in suspend mode, 15 K ± 5% termination resistors on D+ and D– pins; all ports con-
figured as inputs; OSC2 capacitance linearly affects wait IDD.
5. STOP IDD measured with USB in suspend mode, OSC1 grounded, 1.425 K ± 1% pull-up resistor on D+ pin and 15 K ± 1% pull-
down resistors on D+ and D– pins, no port pins sourcing current.
6. Maximum is highest voltage that POR is guaranteed.
7. If minimum VDD is not reached before the internal POR reset is released, RST must be driven low externally until minimum VDD is
reached.
8. RPU is measured at VDD = 5.0V.
