1. V_DD = 3.3 to 2.7 Vdc, V_SS = 0 Vdc, T_A = –40°C to +85°C, unless otherwise noted
2. Typical values reflect average measurements at midpoint of voltage range, 25°C only.
3. Run (operating) I_DD measured using internal oscillator at its 16-MHz rate. V_DD = 3.3 Vdc. All inputs 0.2 V from rail. No dc
loads. Less than 100 pF on all outputs. All ports configured as inputs. Measured with all modules enabled.
4. All measurements taken with LVI enabled.
5. Wait I_DD measured using internal oscillator at its 1 MHz rate. All inputs 0.2 V from rail; no dc loads; less than 100 pF on all
outputs. All ports configured as inputs.
6. Stop I_DD is measured with no port pins sourcing current; all modules are disabled.
7. Pullups and pulldowns are disabled.
8. Maximum is highest voltage that POR is guaranteed.
9. Maximum is highest voltage that POR is possible.
