Notes:
1. VDD = 5.0 Vdc ± 10%, VSS = 0 Vdc, TA = –40°C to +125°C, unless otherwise noted.
2. Typical values reflect average measurements at midpoint of voltage range, 25
°C only.
3. Functionality of the MCU is guaranteed during injection of dc. current up to the maximum specified level. The maximum
specified level is the total current for each port and is allowed on a single pin or a combination of pins. Some
disturbance of the ADC accuracy is possible during any injection event and is dependant on board layout and power
supply decoupling.
4. Run (Operating) IDD measured using external square wave clock source (fOP = 8.4 MHz). 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.
5. Wait IDD measured using external square wave clock source (fOP = 8.0 MHz). All inputs 0.2 Vdc 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. Measured with all modules enabled.
6. Stop IDD measured with OSC1 = VSS.
