1. V_DD = 5.0 Vdc ±10%, V_SS = 0 Vdc, T_A = T_L to T_H, unless otherwise noted
2. Typical values reflect average measurements at midpoint of voltage range, 25°C only.
3. Run (operating) I_DD measured using external square wave clock source (f_OSC = 8.2 MHz); all inputs 0.2 V from rail; no dc
loads; less than 100 pF on all outputs; C_L = 20 pF on OSC2; all ports configured as inputs; OSC2 capacitance linearly
affects run I_DD; measured with all modules enabled
4. Wait I_DD measured using external square wave clock source (f_OSC = 8.2 MHz); all inputs 0.2 V from rail; no dc loads; less
than 100 pF on all outputs; C_L = 20 pF on OSC2; all ports configured as inputs; OSC2 capacitance linearly affects wait I_DD;
measured with PLL and LVI enabled
5. Quiescent I_DD measured with PLL and LVI disengaged; OCS1 grounded; no port pins sourcing current. It is measured
through combination of V_DD and V_DDA.
6. Maximum is highest guaranteed voltage for POR.
7. Maximum is the highest possible voltage for POR. If minimum V_DD is not reached before the internal POR reset is released,
RST must be driven low externally until minimum V_DD is reached.
