3.3V DC Electrical Characteristics
Notes:
1. VDD = 4.5 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.
4. Wait 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 wait IDD.
5. The 8kHz clock is from a 32kHz external square wave clock input at OSC1, for the driving the RTC. Due to loading effects,
the IDD values will be larger when a 32kHz crystal circuit is connected.
6. LCD driver configured for low current mode.
7. Maximum is highest voltage that POR is guaranteed.
8. If minimum VDD is not reached before the internal POR reset is released, RST must be driven low externally until minimum
VDD is reached.
9. RPU1 and RPU2 are measured at VDD = 5.0V
