1. Parameters are design targets at VDD = 1.8 V to 3.3 V, VSS = 0 Vdc, TA = –40oC to +85oC, unless otherwise noted
2. Typical values reflect average measurements at midpoint of voltage range, 25°C only.
3. Run (operating) IDD measured using internal clock generator module (fop= 2.0 MHz). VDD = 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. CL = 20 pF. OSC2 capacitance linearly
affects run IDD. Measured with all modules enabled.
4. Wait IDD measured using internal clock generator module, fop = 2.0 MHz. All inputs 0.2 V from rail; no dc loads; less than
100 pF on all outputs. CL = 20 pF. OSC2 capacitance linearly affects wait IDD. All ports configured as inputs.
5. Stop IDD measured with no port pins sourcing current, all modules disabled except as noted.
6. Pullups and pulldowns are disabled.
7. Maximum is highest voltage that POR is guaranteed.
8. Maximum is highest voltage that POR is possible.
9. If minimum VDD is not reached before the internal POR reset is released, RST must be driven low externally until minimum
VDD is reached.
